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

These Sea Surface Height Anomalies (SSHA) are derived from the Jason-1 Geophysical Data Record (GDR) Geodetic Mission. 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_geodetic/ . 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 .

本数据集所述的海面高度异常（SSHA）源自于Jason-1地球物理数据记录（GDR）测地任务。Jason-1是一项测高任务，其仪器对以下参数进行直接观测：测高仪距离、显著波高、海洋雷达回波散射截面（风速的测量指标）、电离层电子含量（通过简单公式计算得出）、对流层水含量以及与GPS卫星星座的相对位置。利用这些参数，可计算出SSHA，并在此数据集中提供。数据格式为NetCDF。请注意，此数据集非项目官方数据集，因此未经审查。若需审查过的产品，您需从GDR产品中计算SSHA，该产品可从PO.DAAC驱动器中获取，网址为https://podaac-tools.jpl.nasa.gov/drive/files/allData/jason1/L2/gdr_c_geodetic/。计算SSHA的文档同样可在PO.DAAC驱动器中找到，网址为https://podaac-tools.jpl.nasa.gov/drive/files/allData/jason1/L2/gdr_c/docs/Handbook_Jason_v4-1.pdf。
