Minimize SMOS data processors

Level 1 Processors (L1OP - NRTP)

The L1 processors are applications that process SMOS Level 0 Products and generate Level 1A, 1B and 1C products.

There are two types of L1 processor:

  • the L1OP which is the operational L1 Processor integrated in the Data Processing Ground Segment (DPGS) and used to generate SMOS data in Earth Explorer format for scientific users
  • the NRTP which is the operational Near Real Time Processor integrated in the NRT Processing Infrastructure and used to generate SMOS data in BUFR format for operational users

For further information about the processing algorithms see the Data Processing Model documents.

Level 2 Soil Moisture Processor (L2SM)

The L2SM processor is designed to retrieve soil moisture, vegetation optical thickness, and other geophysical parameters of interest from L1c data.

For further details about the processing algorithm see the Algorithm Theoretical Basis Document.

Level 2 Sea Surface Salinity Processor (L2OS)

The L2OS processor ingests L1C ocean products, together with ECMWF forecast geophysical data and other auxiliary files, and generates L2 sea surface salinity user data products. The L2OS processor uses three different surface emission models to predict brightness temperature measurements and derives three L2 sea surface salinity fields through an iterative convergence scheme.

For further details about the processing algorithm see the Algorithm Theoretical Baseline Document.
