The workshop focused on plans for calibration and validation (Cal/Val) of SMAP science data products. The workshop provided a forum for scientists from around the world to participate in implementing the SMAP Cal/Val plan, exchanging expert information and resolving key issues.

The SMAP Cal/Val Plan addresses pre- and post-launch Cal/Val activities undertaken to ensure the generation of high quality products and definitive validation of the products. At previous Cal/Val workshops, 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 and applying the diverse in situ resources available for validation.

At the 4th Cal/Val Workshop, results to date were reviewed and plans developed to focus on the post-launch phase of Cal/Val (including product levels L1-L4). A specific objective of the workshop was a review of Cal/Val Rehearsal Phase-I that took place in June-August 2013. (Cal/Val Rehearsal Phase-II is planned for May/June 2014.) The rehearsals are designed to exercise the acquisition, integration, and application of all Cal/Val elements in order to identify and ameliorate issues prior to the actual post-launch Cal/Val. Continued participation in SMAP Cal/Val activities by the broad science community is of importance to the SMAP mission.
