资源简介：
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 a 3 day composite.)

NOAA CoastWatch分发科学级别的Ekman流（包括经向、纬向和模量数据集）及Ekman上升流数据。该数据集的起始点为EUMETSAT Metop-A卫星上ASCAT仪器测量的风速数据。ASCAT是一种微波散射计，旨在测量全球海洋表面的风速。NOAA CoastWatch对风速数据进行处理，转换为风应力及其旋度，最终得到Ekman流和Ekman上升流数据。（此为3日合成数据。）
