The workshop focused on plans for calibration and validation (Cal/Val) of SMAP science products. The workshop provided a forum for over 90 scientists from around the world to review the Cal/Val plan, exchange expert information, resolve key issues, and develop implementation plans.

The SMAP Cal/Val Plan is a mission requirement. The plan addresses both pre- and post-launch Cal/Val activities undertaken to ensure the generation of high quality products and definitive validation of the products. In the pre-launch phase, the Cal/Val focus is primarily on algorithm development and establishment of infrastructure for the post-launch validation.

At the 1st Cal/Val Workshop, science community involvement and activities were initiated to support SMAP Cal/Val objectives. These activities included plans for field campaigns, development of tower and aircraft-based simulators and methods for integrating the diverse in situ resources available for validation.

At the 2nd Cal/Val Workshop, results to date were reviewed and plans developed for the coming year.

Continued participation in SMAP Cal/Val activities by the broad science community through this and future workshops will be of great importance to the SMAP mission.
