Wind, Metop-B ASCAT, 0.25°, Global, Near Real Time, 2013-present, Divergence and Modulus (3 Day)

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. (This is a 3 day composite.)

美国国家海洋和大气管理局（NOAA）海岸监视部门分发由EUMETSAT Metop-B卫星上的ASCAT仪器测量的近实时风向散度和模量风速数据。ASCAT是一种微波散射计，旨在测量全球海洋表面的风速。风速经过NOAA海岸监视部门处理，转换为风向散度。（此为三天合成数据。）
