Weather observations are typically collected by professional devices siting in open spaces. These weather stations provide very precise measurements, but they also require a regular maintenance and calibration of the sensors, which implies a high cost for national weather services. In general terms, one could say that we are good with the current weather forecast. In the end, the combination of in-situ measurements with numerical weather models and remote sensing data, provides a decent weather forecast for several days in advance.
If you reached here by chance, just be sure of reading the first part of the post first, in which we explain why a Drought Monitor is necessary. In this second part, you can find a longer description of the technical aspects of the development of this prototype.
Technicalities This section does not intend to be an exhaustive description of the processing required to develop the prototype, but to provide a high level description.
The Netherlands is a country in a constant battle with increasing water levels, especially since the 14th century. Canals, dykes, and polders are part of the landscape and intrinsically rooted in the Dutch culture. You would expect that rainfall is ensured in this northern European country, that is why everything is so green and shiny, right? Well, this might (gradually) not be the case anymore, because climate change seems to have altered the regional precipitation patterns that have showered this country for centuries.
