With much of Europe recently subjected to a prolonged heatwave and lack of rain, brown was certainly the trending colour this summer. This Copernicus Sentinel-2 image was taken on 24 July 2018 and shows brown fields around Chippenham in Wiltshire, UK.
The two Copernicus Sentinel-2 satellites carry high-resolution multispectral optical imagers to monitor changes in vegetation. The mission offers measurements of leaf area index, leaf chlorophyll and leaf water content, which allow for a detailed assessment of plant health.
