ESA ERS-1 and ERS-2 Scatterometer Ocean Surface Winds

There are several products available in this dataset. * Wind direction and speed derived by JPL from the scatterometer instrument aboard the ERS-1 and ERS-2 satellites. These along swath orbit data are online at NCAR. However, due to restrictions place on the data usage, by the European Space Agency (ESA), data users must first receive permission to use this dataset. Questions concerning permission should be directed to: * The above ERS products were archived in the 1990s and are quite old versions. Better versions are available through European KNMI/ESA sources. [https://scatterometer.knmi.nl/archived_prod/] * 1-degree by 1-degree, 80S to 80N, monthly mean grids for ERS1 (1991.01-1996.05) and ERS2 (1996.04-1999.12). These data were obtained directly from CERSAT, IFREMER, France. [http://cersat.ifremer.fr/] Extant variables include wind speed, u- and v- wind components, stresses, divergence and curl.

本数据集包含多款科研产品。
* 由美国喷气推进实验室（JPL）基于欧洲遥感卫星1号（ERS-1）与欧洲遥感卫星2号（ERS-2）搭载的散射计（scatterometer）仪器反演得到的风向与风速数据。此类沿轨条带轨道数据可在国家大气研究中心（NCAR）获取。但由于欧洲空间局（ESA）对数据使用施加了相关限制，数据使用者需先获得本数据集的使用许可。有关使用许可的相关咨询，请联系：
* 上述ERS系列产品于1990年代完成归档，属于较为老旧的版本。更优质的同类数据可通过荷兰皇家气象研究所（KNMI）与欧洲空间局（ESA）的官方渠道获取。[https://scatterometer.knmi.nl/archived_prod/]
* 分辨率为1度×1度、覆盖范围为南纬80°至北纬80°的逐月平均格点数据，对应欧洲遥感卫星1号（1991.01-1996.05）与欧洲遥感卫星2号（1996.04-1999.12）的观测时段。此类数据直接从法国海洋开发研究院卫星海洋学中心（CERSAT, IFREMER）获取。[http://cersat.ifremer.fr/] 数据集包含的现存变量包括风速、u分量与v分量风场、风应力、散度与涡度。
