Wind-speed data based on ocean surface using GNSS-R

December 6, 2016By

The National Oceanography Centre (NOC) has developed global wind speed products based on reflected GPS signals, using data from the UK TechDemoSat-1 satellite, reports Hydro International. The achievement demonstrates the potential of GNSS reflectometry (GNSS-R) to improve sampling of ocean surface winds, as well as improve weather monitoring and forecasting by complementing existing satellite measurements from scatterometers and radiometers. The... read more
