Global ultraviolet (UV) surface reflectivity climatologies are all composed from daylight passive remote sensing observations of reflected UV light, generally integrated over a distribution of attainable reflection directions. We discovered the sensitivity of Aeolus lidar surface returns (LSR) to surface characteristics, providing the first evidence that active remote sensing can be effectively used for retrieving unidirectional UV surface reflectivity on global scales. LSR reproduces surface reflectivity monthly changes in Sahara, which are visible in the Lambertian Equivalent Reflectivity (LER) climatologies from TROPOMI and GOME-2.

Article Synopsis
- Satellite microwave sensors have been measuring near-surface ocean winds for almost 40 years, contributing significantly to weather and climate research through systematic data collection.
- Various wind datasets are being intercalibrated and merged into consistent climate data records (CDRs), with evaluations done in comparison to ocean buoys and other satellite sensors.
- Future data continuity depends on utilizing new satellite missions like OSCAT-2, which will face calibration challenges due to the failure of RapidScat, as there are currently no new radiometer missions planned to measure wind speed.
