Fig. 2 - S2 (22.11.2020 18:47) - Sentinel-2 was launched in 2015 & 2017, both with a 10-day cycle. Each has 4 10m VNIR, 6 20m IR & 3 60m absorption bands.
Fig. 3 - L7 (23.11.2020) - Landsat-7 was launched in 1999, its sensor has 6 30m optical bands, a 15m panchromatic & a 60m thermal IR. It has a 16-day cycle.
Fig. 4 - L8 & S2 (22.11.2020) + L7 (23.11.2020) - Using similar bands, these 3 sensors complement each other by increasing acquisition frequency & archive period.
