This dataset consists of the unprocessed radiance measurements downloaded directly from the unmanned aerial system imaging platform used to image the ice sheet surface near UPE_U in the north-west of the Greenland Ice Sheet, along with captures of reflectance panels and sensor calibration parameters which enable these imagery to be transformed to reflectance measurements. Funding was provided by the NERC standard grant NE/M021025/1. : Flights occurred on: 2018-07-23 2018-07-24, am 2018-07-24, pm 2018-07-26 Precise flight times are encoded in TIFF headers.
