SMOS Pilot-Mission Exploitation Platform

Pi-MEP data source

The Pi-MEP downloads, regularly updates, archives and processes an ensemble of required input datasets that are used by the platform to perform satellite SSS remote sensing analyses. There are several types of data:

  • Satellite SSS Core datasets (L2/L3/L4)
  • In situ Core datasets
  • Auxiliary geophysical datasets
  • Numerical Weather Prediction (NWP) and Numerical Ocean Prediction (NOP) datasets
  • Process study dedicated datasets

These datasets are described in detail in the tables here below:
