This workshop will focus on the calibration and validation (Cal/Val) of SMAP science data products. The workshop provides a forum for scientists from around the world to participate in implementing the SMAP Cal/Val plan, assessing performance to date, exchanging expert information and resolving key issues.

The SMAP Cal/Val Plan addresses Cal/Val activities undertaken to ensure the generation of high quality products and definitive validation of the products after launch. These activities include instrument calibration and a suite of validation methodologies that include core validations sites, sparse observing networks, inter-comparisons with other satellite missions providing similar products, model-based inter-comparisons, and field campaigns.

All products will be assessed and plans for further evaluation and improvement will be discussed. Results of recent field campaigns will be reviewed. A specific focus of the workshop is to finalize the planning for the 2019 field experiment to support algorithm enhancements for forest biomes. The SMAP mission regards highly the continued participation of the broad science community in the SMAP Cal/Val activities.

The workshop will be followed by the 5th Satellite Soil Moisture Validation and Applications Workshop held at the same location. More information is provided here.
