Report on the NIST workshop of December 10, 2009: calibration strategies for bridging possible climate data gaps

A one day workshop was held on December 10, 2009 at the National Institute of Standards and Technology to address the issue of data gaps in the time series of satellite measurements. Such gaps can occur due to launch delay or failure, or inconsistencies or data jumps in radiometric scales between satellites, and limit the use of measurements to effectively detect climate change. Leading experts in the Earth Observation community from NASA, NOAA, USGS, and academia attended the meeting to prioritize the calibration strategies for bridging and mitigating satellite data gaps for climate change detection. These strategies include establishing SI traceability for all satellite calibrations and measurements; continued improvements in prelaunch, onboard, and vicarious calibrations and transfer standards; establishing celestial standards and procedures for intercomparisons; establishing SI traceability for alternative measurement strategies, such as in-situ networks and air borne sensor campaigns; and leveraging international satellite assets. This paper summarizes the workshop and recommendations.
