RainGain is a project within the Framework of the COP21 Preparation and stands for



The EU INTERREG NWE IVB RainGain project has focused on recent remote sensing technologies to achieve a finer urban water management and to build up resilience to weather extremes and climate change. The RainGain conference will address all the issues related to high-resolution rainfall measurement, nowcasting and hydrological modelling, as well as their advanced applications to urban water management and stakeholder’s capacity building.

The poster that was presented was titled: ” Dual-Polarimetric X-Band Weather Radar: Accurate Rainfall Estimation and Storm Observations ” and can be found here.

On Wednesday 29th October 2014 was the official kick-off meeting of Waterlab which took place in the Science Center of TU Delft (link1, link2). Almost 300 pupils from primary schools of Delft had a first hint about science and rain measurements.

Currently, four primary schools in Delft area are involved in the project. The teachers and pupils measure local precipitations with handmade raingauges and compile all measurements to a dedicated website called MijnWaterlab. Besides these observations, rainfall intensities are also measured continuously since September 2014 with weather stations located in each of these schools (see picture on the right) in order to have a better idea about the variability of precipitation at the scale of a city. Easy comparisons can be made between each dataset.
On the other hand, in the upcoming weeks, students from secondary schools from Delft will integrate the project and the roof of these lyceums will be equipped with a station for measuring rainfalls. The students there will have to deal with scientific projects in relation with the analysis of these observations.


Since today, another weather station is also located in the Science Center to continue with the densification of the network of stations in Delft. The particularity of this station is that the data are collected automatically via wired internet connection with the use of a RaspberryPi-based system (see picture on the right) that was under development during the last months.
A quasi-similar configuration (using 3G wireless internet connection) will be applied very soon to the stations installed in schools (currently a visit to each school is needed to manually collect the data).

On March 27th started the WaterLab Delft project.


This project is a collaboration between different organizations:
Gemeente Delft and Gemeente Rotterdam,
HH van Delfland and HH van Schieland en de Krimpenerwaard,
Unie van Waterschappen,
Hogeschool Rotterdam,
UNESCO-Institute for Water Education,
TNO, Deltares and TU Delft.

It consists in a better understanding of the water cycle in urban areas. It involves specialists of the water cycle and of the atmosphere and also students/pupils. It implies education and improvement of knowledge.

Edouard Martins from our group is currently working with three TU Delft students (David Kester, Ingo Schilken, Tim Gebraad). Their current work is to deal with the calibration of sensors mounted on several weather stations for a better accuracy of meteorological parameters (temperature, pressure, humidity, rain, wind, radiation) and for a better assessment of the impact of urban features (buildings, trees) in the measurement of these quantities.

The next step is to deploy several calibrated weather stations in high schools located in Rotterdam and Delft to have a better representation of the variability of these meteorological parameters in the urban areas of South Holland.

You can find more information in the official webpage of the project (in dutch).

More updates and pictures will come soon.

One of the goal of the RAINGAIN PROJECT is to obtain high resolution weather and improve urban hydrology models to better manage flash flood events over urbanized cities. Four populated cities, London, Leuven, Paris, and Rotterdam were chosen to conduct initial planning and research.  In Rotterdam, a Doppler X-band radar with polarimetric capabilities will be installed in January 2014 on top of the Nationale Nederlanden office building at the Delftse Poort twin-tower skyscraper complex.

The 1st RAINGAIN conference paper from TUDelft was submitted for the 36th AMS Radar Meteorology Conference held in Colorado, USA:
