Operational Geophysical Data Record (netCDF) - SARAL

The Operational Geophysical Data Record (OGDR) is a near real-time operational product delivered to users within 3 - 5 hours from instrument sensing. The main geophysical parameters in the OGDR product, derived from the AltiKa Ka-band altimeter on-board the SARAL satellite, are significant wave height and ocean surface wind speed. Additionally, all necessary magnitudes contributing to the estimation of the sea surface height are provided as well, such altimeter ranges, orbit data (altitude), water vapour correction, geophysical corrections and geophysical references. Finally, other important parameters, intended to help with the interpretation and use of the data for different applications, are provided as well, such as for example backscatter coefficients and a range of instrument and processing quality flags. Both 1Hz and 20Hz sampling data are included. This product is mainly targeting operational weather and ocean forecasting applications. This data set is generated by EUMETSAT.
