NEWS Water and Energy Cycle Climatology

NASA’s Energy and Water Cycle Study (NEWS) program supported an assessment of the state of the global water and energy cycles at the start of the millennium, based on data from the most advanced space and ground based measurement systems and output from observation-integrating models (Rodell et al., 2015; L’Ecuyer et al., 2015).  This was a critical step towards the NEWS objective of evaluating water and energy cycle consequences of climate change.  The study team, which included 24 scientists from 14 institutions, used modern observation-integrating products and associated error-analyses to develop a climatology of water and energy fluxes for each continental/oceanic region and the global scale.  The assessment serves as a baseline for studies of climate related water and energy cycle changes and as a benchmark for evaluating climate prediction models.
