How well can we map NPV across temperate forest heterogeneity? Can we use NPV time series to reveal tree dieback? And how does dieback vary between species in Germany?

Observations from 3 #Sentinel2 satellites! Increased revisit frequency. Terrific news!
“This configuration will enhance the availability of Sentinel-2 data, with additional Sentinel-2 observations on the same relative orbit, occurring 2 days apart from Sentinel-2B and 1 day apart from Sentinel-2C.”
“This configuration will enhance the availability of Sentinel-2 data, with additional Sentinel-2 observations on the same relative orbit, occurring 2 days apart from Sentinel-2B and 1 day apart from Sentinel-2C.”
ESA has granted Sentinel-2A a one-year exceptional and temporary extension, delaying its retirement and increasing Sentinel-2 revisit times.
