Nighttime lights map of the contiguous US. 🔴: 2012, 🟢:2016, 🔵: 2020. Note the (blue-dominant) color in North Dakota and Texas, due to increased gas flaring over the 8 year period shown.
Note: These two fillings have only partially filled the GERD reservoir. The reservoir is so massive, it would require entirely damming the Blue Nile (containing 80% of Nile’s total flow) for approximately 1.5 years to fill to capacity.
How much water is stored to run a hydropower plant 3x the size of the Hoover Dam? Check out the first and second fillings of the Grand Ethiopian Renaissance Dam reservoir.
The images shown are Sentinel-1 GRD mosaics, collected via the @DescartesLabs platform. vh polarization is displayed in the red and green bands, and vv polarization is displayed in the blue band.
#NDVI and #EVI have always been essential tools for assessing the health of vegetation. But plants don’t stop growing when it’s cloudy, so @DescartesLabs science intern @terrymconlon shows us how VI's can be derived using cloud-penetrating radar.
