This document addresses the need for systematic assessments of the quality of data sets used in various applications such as climate services and climate science, including their use in the evaluation of climate model performance.
Precipitation Assessment Report – May 2008
Evaluating the reliability of available, global, long-term precipitation data products in depicting the variations of precipitation at larger-than-weather scales with a special emphasis on the GPCP product.
Cloud Assessment Report – Nov. 2012
Assessing the reliability of global, long-term cloud data sets. See also the Cloud Assessment website.
Radiative Flux Assessment – Dec. 2012
Providing a forum for consistent analysis of long-term radiative flux products, primarily top-of-atmosphere and surface fluxes, to establish a foundation for better global radiation budget analysis.
Chair: Paul Stackhouse (2004 – Present)
Assessing the quality and compatibility of global aerosol products with a focus on the Global Aerosol Climatology Project (GACP).
Chairs: Sundar Christopher (2008 – Present) and Jeffrey Reid (2008 – Present)
Quantifying the state of the art in water vapor products being constructed for climate applications.
