a–c show true color imagery from Landsat 8 with the location of transect in red. The lower panels in a–c show same-day albedo (red line) from the MCD43A3 product and fractional water area (blue fill) from ref. 32. a North Greenland on Jul 30, 2019, b Northeast Greenland on Aug 02, 2019, and c Southwest Greenland on Aug 04, 2019.
