Presentation by Dr. Einfalt at the ICUD in Melbourne

Our task in the EU H2020 project WaterSENSE is to provide high quality precipitation data for various applications.
The goal is to provide the best possible precipitation data for each location worldwide. Depending on availability, this can be radar data calibrated with rain gauges or satellite-based precipitation data. As an example for the Namoi catchment (New South Wales, Australia), Dr. Einfalt presented our approach at the ICUD (25. – 28. 10. 2021 in Melbourne).

Thai Radar Composite – Completion of Project HII Phase III

On behalf of the Thai Hydro Informatics Institute (HII), hydro & meteo GmbH has built up a real-time system that processes precipitation data processed for Thailand and calculated nowcasts.

The real-time system is based on the SCOUT (hydro & meteo) software. It is updated every 6 minutes with new radar measurements and includes the steps:

  • Import of radar measurement data from 9 radars
  • Correction of the radar measurement data
  • Composition on a common 1km x 1km grid
  • Import of current rain gauge measurements from over 500 stations
  • Calibration of the radar measurements with rain gauge measurement data
  • Calculation of nowcasts
  • Sending email warnings when rain tresholds are exceeded

The calibrated radar measurements and nowcasts are shown on the Thai website.

As part of the 3rd project phase, the existing composite of 5 radars was expanded to a composite of 9 radars, which covers all of Thailand. The Rongkwang, Banphue, Rasisalai and Pathio radars have been added. Takhli replaces the Inburi radar.

Hail detection based on dual polarization measurement data is used as a new functionality.

The new system, which is used among other things for heavy rain warnings, has been operational since the end of August 2021.

Flood disaster in NRW and RLP

On July 14, 2021, there was long lasting heavy rainfall in the federal states of North Rhine-Westphalia and Rhineland-Palatinate with precipitation amounts of up to 200 mm.

A main task of hydro & meteo is the analysis and processing of precipitation from heavy rain events on the basis of radar measured data. With this we support affected communities and associations in their endeavour to improve prevention measures.

Evaluations were carried out for several municipalities, water associations and the state of North Rhine-Westphalia for this event and partly also for the event on June 4, 2021.

Climate outlook from the Climate Service Center Germany

Scientists at the Helmholtz Center in Geesthacht have calculated climate changes more specifically. The Lübecker Nachrichten reported on July 14th how Lübecks climate is also changing. Even if the model calculations are burdened with uncertainties: the summers will be hotter, the winters wetter, and an increase in heavy rain events must be expected.
hydro & meteo have developed the comprehensive information portal i-square on heavy rain together with the climate control center of the city of Lübeck:
Use our checklists to find out about the individual risks and dangers of the location and property.
And get specific remedial measures against the various effects of heavy rain.

3rd Bochum Hydrometry Colloquium on February 24th, 2021

The team from the Department of Civil and Environmental Engineering at Bochum University invites you to the digital conference on current topics in hydrometry on February 24th.

Dr. Thomas Einfalt from hydro & meteo GmbH presents in his lecture “When can you call a trend a trend? Considerations on trends in time series” current findings on the assessment of measured values from two different research and development projects in North Rhine-Westphalia (“ExUS – extreme value statistical analysis of heavy rain precipitation in NRW” and “UnIWa – Investigations into the use of transient design approaches in water management practice”).

In these two different projects long time series of precipitation measurements have been investigated for instationarities (trends and change points). The presented results are focused around the question when an increase of precipitation can be considered a trend in the data. It is demonstrated that change points may occur in the statistics of short durations which cannot be attributed to a modification of the measurement procedures.

The lecture emerged from a collaboration between Dr. Thomas Einfalt and Benedikt Rothe and Tobias Gehrmann, employees of Hydrotec, Vera Schmimetzek, State Office for Nature, Environment and Consumer Protection (NRW), Prof. Dr. Ing. Markus Quirmbach, Ruhr West University and Fabian Netzel, Bochum University, hydraulic engineering and hydromechanics emerged.

The Bochum Hydrometry Colloquium 2021 will be carried out in coordination and with the support of the Federal Institute for Hydrology (BfG), the State Office for Nature, Environment and Consumer Protection North Rhine-Westphalia (LANUV) and the Expert Group on Hydrological Sciences in the DWA (FgHW).

We have provided you with the link to register for the conference (possible until February 5th) and the program flyer (in german language) here.

Expansion of the Hamburg inland flood warning system

hydro & meteo GmbH is currently working on the expansion of the Hamburg inland flood warning system. The extensions will be integrated into the inland flood warning system ( within the coming months.

There will be several innovations in the public area of the website, including:

  • Current radar measurements and radar nowcasts
  • Maximum precipitation forecast for Hamburg
  • A three-level symbol to indicate the current warning status. This enables a quick overview of warnings due to high water levels, precipitation and precipitation forecasts.

In the internal area, a lot of additional information is made available to the employees of the LSBG, including a short-term precipitation forecast generated by hydro & meteo. This is a combination (‘blending’) of radar nowcasts and the numerical weather forecast COSMO-D2-EPS of the DWD.

The extensions were made as part of the BMBF project StucK developed and tested. The client is the State Office for Roads, Bridges and Waters (LSBG).

hydro & meteo participates in the “Unter 1000 mach ich’s nicht” campaign

Commitment to refrain from (short-haul) business flights to destinations of less than 1,000 km distance or than 12 hours travel time

hydro & meteo participates in the “Unter 1000 mach ich’s nicht” campaign which scientists4future joined, too. Even if air traffic accounts for only approx. 3% of CO2 emissions worldwide, the so-called height effect was not included in this calculation, nor was the fact that, when kerosene is burnt the released aerosols and nitrogen oxides make a significant contribution to climate impact. The negative effects of flying are therefore estimated to be two to five times as high (see atmosfair and the assessment of the Federal Environment Agency based thereon).

Since the number of flights within Germany continues to increase year by year and the railroad network of the German railway company is to be significantly expanded by 2030 and already offers a mobile substitute for short distance air travel, a contribution toward climate neutrality can be made by dispensing with domestic flights within Germany.

Let us reflect and modify our everyday mobility decisions towards more mobility on foot, by bike, bus and train: we already did!

article on heavy rain in the regional daily newspaper “Lübecker Nachrichten”


The newspaper “Lübecker Nachrichten” again reports on the dangers and risks of increasing heavy rainfall events as a result of climate change. Even if Lübeck has so far been affected by extreme weather events less frequently than other regions, “(…) the rise in temperature in Schleswig-Holstein (…) is more pronounced than the global average” (The LN quots  Dr. Thomas Einfalt from hydro & meteo GmbH).

hydro & meteo GmbH has already been working in various projects with the Hanseatic City of Lübeck on municipal climate adaptation. The RainAhead project (“Rain in Sight”) has created planning and warning tools for heavy rain in the urban areas. The follow-up project i-quadrat, funded by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety as a”municipal lighthouse project for adaptation to climate change” for the years 2018-2020, focuses primarily on the issue of precautionary measures with regard to heavy rainfall events. Further goals are the development of local and regional cooperation as well as the intensification of communication with citizens and other target groups.

Newspaper articles, workshops and brochures on the dangers of heavy rain and how to protect oneself against them are increasingly raising awareness of this topic among the population.

ExUS 2020 – Flyer on heavy precipitation in North Rhine-Westphalia now published


Extreme precipitation events have become more prevalent in recent decades, according to the results of the study “Extreme Value Analysis of Heavy Rainfall in North Rhine-Westphalia (ExUS) 2010”.

As a continuation of the ExUS 2010 project, hydro & meteo GmbH is once again working on the ExUS2020 study in a cooperation agreement with the State Office for Nature, Environment and Consumer Protection of North Rhine-Westphalia (LANUV), dr. papadakis GmbH, aqua_plan GmbH and Dr. med. Markus Quirmbach (Head of the Department of Hydrology, Urban Water Management and Hydraulic Engineering at the Ruhr West University of Applied Sciences (HRW), in which measurement data taken during ten additional years will be examined and used for evaluation.

Questions arising from the consequences of climate change have become more and more complex. In particular, the development of shorter duration heavy rainfall, changes in air temperature and dry periods as well as findings from spatially high-resolution radar precipitation data have not only rendered a new edition necessary, but also an expansion of the scope of research of the new ExUS 2020 study.

HydroNET SCOUT event database

With radar climatology of the German Weather Service (DWD)

hydro & meteo GmbH has created the concept for an event database in order to simplify the evaluation of extensive radar data sets. This was implemented by HydroLogic B.V. for four water boards in North Rhine Westphalia (NRW) based on the HydroNET portal. In the area of ​​NRW, the database includes high quality data from 2001 to 2016 with a resolution of 1km x 1km and a time step of 5 minutes for the complete area of NRW. The data set consists of carefully semi-automatic radiated data checked and corrected with SCOUT (database: DX product of the German Weather Service), which was adjusted with the help of quality-controlled rain gauge data from more than 900 stations in NRW.

The event database offers innovative solutions in the areas of risk management, extreme values ​​and easy data access. A special search algorithm was developed, which searches the dataset for spatially and temporally independent precipitation events. This allows to search for events of different duration intervals above selectable rainfall levels and for different area sizes in different search areas. The access to the event database is direct via the web portal HydroNET.

Since the end of 2018, the radar climatology of the German Weather Service is available via Open Data and since the beginning of this year this dataset can also be accessed in the event database. This data set contains post-processed and adjusted Radolan radar data with a resolution of 1 km2 and 5 minutes across Germany from 2001 to presently January 2018.

Day of Geodata Infrastructure Schleswig-Holstein 2019

The day of Geodata Infrastructure Schleswig-Holstein 2019 (GDI-SH) took place on of february in the Audimax of the Christian-Albrechts-University in Kiel. hydro & meteo took part of it and presented in the context of its project i-quadrat a stand on the topic “heavy rain – damage minimization with the help of INSPIRE compliant data”. The project i-quadrat is funded by the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety for the years 2018-2020. It deals primarily with the topic of prevention for heavy rain events and takes up the results of the project RainAhead (2013 – 2016) in order to communicate with citizens and other target groups.

The event, titled “GDI-SH – A Sea of ​​Data”, focused on the importance of geodata for the work of state and local government, as well as for business, science and the public, and their benefits in dealing with social challenges.

Closing event of the joint project “StucK” on 22. 08. 2018

On August 22, 2018, the closing event of the joint project StucK(“Ensuring the drainage of coastal, urban areas considering the climate change”) took place in the conference center at the Department of Environment and Energy in Hamburg.

At the event, the most important project results and their possible applications were presented and discussed with the participants. In our work package we have produced combined ensemble predictions from radar nowcasts and numerical weather forecasts (COSMO-D2-EPS). Furthermore, we have created an operational test warning platform as an extension of the existing warning system “Binnenhochwasser Hamburg” ( In addition to the water level measurements, the measured water levels of the respective catchment areas and the improved precipitation forecasts now also flow into the warning status of the individual water levels. Also we have integrated additional radar products into the system to analyze the current precipitation event. The high-resolution precipitation forecasts are passed on to the Technical University of Hamburg for modeling, which calculates effluent ensembles.

In order to continue the successful work, the funding of the StucK project has been extended for another year until 30.09.2019.

The extension phase is about putting the results of the project into practice. In particular, an action plan and management plan for the implementation of dry and temporarily wet flood retention basins shall be developed. These have proven to be beneficial in the StucK project, both in terms of their contribution to flood protection and from an ecological point of view.

The 2nd HydroNET LIVE Event took place in Amersfoort, Netherlands

On September 13th, the second edition of the HydroNET LIVE event took place in Amersfoort, the Netherlands. The topic of this biennial event was called “Smart water management without borders”. During the event many interesting smart water management case studies were presented and it was an excellent opportunity to meet other water managers from the HydroNET community.

Two masterclasses where specially organised for the international HydroNET community: Showcases of Dutch and international HydroNET implementations to support smart water management. Over 3000 water professionals in 12 countries use HydroNET as decision support tool for the analysis and sustainable management of water resources. In this masterclass more than twelve users and partners from the Netherlands, Australia, South Africa and Germany demonstrated why and how they use HydroNET in their daily practice. They explained how HydroNET helps them to make well-informed and transparent smart water management decisions and why and how they share information with internal and external stakeholders and which boundaries are broken.

Thomas Einfalt and Alexander Strehz from hydro & meteo presented two applications from German HydroNET users. Thomas demonstrated solutions for the quality assurance of precipitation data developed for the State Office for Agriculture, Environment and Rural Areas Schleswig-Holstein (LLUR). In addition, at an information desk Alexander informed about the application “Event Database”. This combines a large high quality data pool in high spatial and temporal resolution with easy access to the data via HydroNET. It hus enables, among other things, the simple use of the data for the dimensioning of water management structures.
