Wind Diffusivity Current, Metop-A ASCAT, 0.25°, Global, Near Real Time, 2009-present (8 Day)

NOAA CoastWatch distributes science quality Ekman current (in zonal, meridional, and modulus sets) and Ekman upwelling data. This data begins with wind velocity measurements from the ASCAT instrument onboard EUMETSAT's Metop-A satellite. ASCAT is a microwave scatterometer designed to measure surface winds over the global ocean. NOAA CoastWatch processes wind velocity to wind stress and wind stress curl, and finally to Ekman current and Ekman upwelling. (This is an 8 day composite.)

美国国家海洋和大气管理局（NOAA）海岸监视部门发布了科学级别的埃克曼流（包括纬向、经向和模量集）及埃克曼上升流数据。该数据集的起始数据来源于欧洲中期天气预报中心（EUMETSAT）的Metop-A卫星上搭载的ASCAT仪器所测量的风速。ASCAT是一种微波散射计，旨在测量全球海洋表面的风速。NOAA海岸监视部门将风速数据加工成风应力、风应力旋度和最终形成埃克曼流和埃克曼上升流。该数据集为8天合成数据。
