Climate Data Center.

Climate Data Center (CDC) Logo

Since 2000 ‘ask’ has been providing IT consultancy and software solutions for the Climate Data Center (CDC) of the German Weather Service (DWD). In particular, we have been supporting their climate and environment activities and research.

In times of global climate change, climate monitoring is vital. Its documentation, and the prediction of the impacts of climate variations, have become essential to the general understanding of the climate. The outcome of this work forms the basis for political and commercial decision-making. It also helps improve preparedness for weather-related catastrophes and provides sustainable support for disaster control.

  • Climate monitoring for the Global Surface Network Monitoring Centre (GSNMC)
  • Climate consulting with WEather data and Statistics Express (WESTE)
