Wind, Metop-B ASCAT, 0.25°, Global, Near Real Time, 2013-present, Divergence and Modulus (1 Day)
收藏资源简介：
NOAA CoastWatch distributes near real time divergence and modulus wind data originating with wind velocity measurements from the ASCAT instrument onboard EUMETSAT's Metop-B satellite. ASCAT is a microwave scatterometer designed to measure surface winds over the global ocean. Wind velocity is processed to wind divergence by NOAA CoastWatch.
