Jason-1 Geophysical Data Record (GDR) Sea Surface Height Anomaly (SSHA) NetCDF

These Sea Surface Height Anomalies (SSHA) are derived from the Jason-1 Geophysical Data Record (GDR). Jason-1 is an altimetric mission whose instruments make direct observations of the following quantities: altimeter range, significant wave height, ocean radar backscatter cross-section (a measure of wind speed), ionospheric electron content (derived by a simple formula), tropospheric water content, and position relative to the GPS satellite constellation. Using the various parameter the SSHA can be calculated and are provided in this dataset. The data are in NetCDF format. This is not the official dataset from the project and therefore not vetted. If you require a vetted product you will need to calculate SSHA from the GDR product which can be found in PO.DAAC Drive at https://podaac-tools.jpl.nasa.gov/drive/files/allData/jason1/L2/gdr_c/. The documentation has the calculation for SSHA and can be found in PO.DAAC Drive at https://podaac-tools.jpl.nasa.gov/drive/files/allData/jason1/L2/gdr_c/docs/Handbook_Jason_v4-1.pdf.

本数据集所呈现的海面高度异常（SSHA）源自于 Jason-1 地球物理数据记录（GDR）。Jason-1 是一项高度计任务，其搭载的仪器对以下量进行直接观测：高度计距离、显著波高、海洋雷达后向散射截面（风速的衡量指标）、电离层电子含量（通过简单公式计算得出）、对流层水含量以及相对于 GPS 卫星星座的位置。通过这些参数，可以计算出 SSHA，并在此数据集中提供。数据格式为 NetCDF。请注意，此数据集并非项目官方数据集，因此未经审查。如需审查过的产品，您需要从 GDR 产品中计算 SSHA，该产品可于 PO.DAAC 驱动器中找到，网址为 https://podaac-tools.jpl.nasa.gov/drive/files/allData/jason1/L2/gdr_c/。有关 SSHA 的计算方法及相关文档可于 PO.DAAC 驱动器中的 https://podaac-tools.jpl.nasa.gov/drive/files/allData/jason1/L2/gdr_c/docs/Handbook_Jason_v4-1.pdf 获取。
