RapidScat L2 25 km winds data record, release 1

Released Climate product

The RapidScat scatterometer onboard the International Space Station (ISS) provided observations from 3 October 2014 - 19 August 2016. Reprocessed RapidScat L2 25 km and 50 km winds Data Records have been created, using the Pencil Beam Wind Processor (PenWP) with RapidScat level 1b data from the NASA JPL PO.DAAC and ERA5 re-analysis outputs from ECMWF.
