A new SAR Water Index derived from Sentinel-1 shows nice correlations with optical NDWI from Sentinel-2.

The SWI is useful for drought monitoring of cropland.

On ESA web-site a new article was published about flood detection in Argentina.

We used ESVI in different variations to show the extent and evolution of a flood event, which took place on Feb 14, 2020 in Santiago Estero Province.

In rainy seasons we often have no access to optical images. Sentinel-1 SAR data is the perfect alternative to create map products from time-series data.

Many thanks again for the editorial support to Mali Cecere.

ESA published an article on their web-site concerning the detection of wildfires in Australia with Sentinel-1 data.

(Fire Information for Resource Management Systems) from Nasa with Sentinel-1 SAR data.

Clouds and smoke influence the optical signal. Sentinel-1 SAR can measure the changes independently.

Many thanks for the editorial support to Mali Cecere.
