The Mission of the ESRL Physical Sciences Division (PSD) is to address physical science questions of short- and long-term societal and policy relevance within NOAA's Climate and Weather and Water Goals, while conducting the physical process research necessary so that ESRL can help provide the nation with a seamless suite of information and forecast products ranging from short-term weather forecasts to longer-term climate forecasts and assessments.

PSD's scientific goal is to provide the observation, analysis, and diagnosis of weather and climate physical processes necessary to increase understanding of Earth's physical environment, including the atmosphere, ocean, cryosphere, and land, and to enable improved weather and climate predictions on global-to-local scales.
