Summary

Description
English: Due to a prolonged period of dry weather, according to local authorities, the Czech Republic is facing its worst drought in 500 years and the areas most affected by the phenomenon are those around Prague and Brno. This image allows us to compare, for an area east of Prague, the Normalised Difference Moisture Index (NDMI) derived from data acquired by one of the Copernicus Sentinel-2 satellites on 3 June 2019 and on 18 May 2020. The NDMI is provides values sensitive to the amount of water available in the soil and in the vegetation, and here shows, in red, that the water deficit areas in 2020 are much greater than those of 2019. In addition to the use of data derived from the satellites of the Copernicus Sentinel-2 mission, drought monitoring can be carried out with data obtained from the Copernicus Sentinel-1 mission. The RADAR data, independent of cloud cover, obtained by the Sentinel-1 mission are particularly suitable for describing dynamics between dry and wet seasons.
