Download SMOS data from the SMOS Online Dissemination Service. An EO Sign In account is required to access the service.
SMOS data is freely and openly available to everyone.
SMOS data quality information covering monitoring of science and calibration products, providing monthly overviews of the health of the MIRAS instrument and product quality, and any MIRAS instrument anomalies that may affect the quality of data acquired.
A number of tools are available for visualising, processing and analysing SMOS data.
The SMOS Toolbox provides visualisation of Level-1C and Level-2 products in the Sentinel Application Platform (SNAP).
The SMOS Data Viewer (SDV) provides a quick and easy way to view SMOS products and the auxiliary files used for generating Level-1 and Level-2 products.
The SMOS Global Mapping Tool (GMT) is useful for plotting SMOS data into a single global geographical map. The GMT is also able to visualise additional quantities derived from SMOS data.
SMOS NetCDF Conversion Tool
The SMOS NetCDF Conversion Tool is a self contained command line executable to be used for batch processing of large amounts of files.
RWAPI can be used to extract information from Level-1 or Level-2 data files in Matlab, as it reads all products related to the retrieval of soil moisture as well as some auxiliary data used as input for the Level-2 processor.
The SMOS Comparison Tool (SCoT) can be used to compare Level-1 SMOS products of the same type generated with the same schema version for the Data Blocks.
The Earth Observation Swath and Orbit Visualisation tool (ESOV) can be used to view and select SMOS orbits, but it does not read any data products.
The SMOS Artificial Scene Library (ASL) function allows users to directly use the L1B product version 7 by mimicking an image reconstruction correction algorithm used in the operational processor.
Calibration and validation activities support the quality measures for SMOS data, by ensuring that the MIRAS instrument is performing well and to established baselines. Ongoing activities are conducted to support this process and reports are available that cover the status and any anomalies that may have occurred throughout the mission lifetime.
