On 23 November 2022 KNMI joined the NL-RIA knowledge network. Contact person is Ad Stoffelen. Together with colleagues he performs scientific research on the use and performance of spaceborne radar instruments, including windscatterometers and altimeters. KNMI’s membership brings in expertise in this field, which strengthens the user side of NL-RIA. Recently a proposal was submitted to ESA in cooperation with TU Delft, in response to a tender for the Retrieval of Ocean Motion Vectors from Scatterometers.
