| Summary: | <!--!introduction!--> Earth’s energy budget drives its climate. Many satellite radiometers have provided top of atmosphere radiation measurements to estimate the energy budget. We present a first look at previously unpublished measurements of Earth-reflected sunlight from broadband pixelated radiometers in the visible and near-visible wavelength range operating on satellites in the Global Positioning System (GPS) constellation since 2011.The radiometers collect synoptic measurements of Earth-reflected sunlight, including polar region coverage, due to the 55° inclination and 20,200 km altitude of the GPS orbits. We present an initial comparison of these radiometers with the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) on the Meteosat-11 geostationary satellite. We also demonstrate the ability of these radiometers to detect changes in reflected sunlight over time. Specifically, measurements ±40 days around the polar summer solstices show (1) reflected sunlight from the Antarctic south of 80°S ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
