Earth Sciences Applications Directorate - The Applied Sciences Directorate is part of NASA's Earth Science Enterprise (ESE). Earth is a dynamic planet; the continents, atmosphere, oceans, ice, and life ever changing, ever interacting in myriad ways. These complex and interconnected processes comprise the Earth system, which forms the basis of the scientific research and space observation that we refer to as Earth system science. The ESE is dedicated to understanding the total Earth system and the effects of natural and human-induced changes on the global environment. Within the Enterprise, the Applied Sciences Directorate is tasked to provide societal benefits through application of ESE research and technology.

WorldWinds: Satellite Derived Global Weather and Wave Forecasting for Commercial and Scientific Applications - WorldWinds provides accurate, high-resolution weather forecasts customized for specific applications. WorldWinds innovative global weather and wave maps are generated by assimilating information acquired from multiple satellite data sources including the TOPEX altimeter, QuikScat scatterometer, and the SSM/I microwave radiometers into customized versions of the COAMPS and MM5 numerical weather models.
The WorldWinds’ product was developed through research and development agreements from NASA and the US Navy. Real-time satellite data is pulled from data taps at the Stennis Space Center’s CNMOC office (Commander, Naval Oceanographic and Meteorology Command) and the NOAA NESDIS facility in Suitland, MD. WorldWinds collects all wind, wave, and weather observations acquired by the satellites and combines them with National Weather Service observations for assimilation into the COAMPS and MM5 models. These models, in combination with NOAA’s WaveWatch model, provide superior forecasts for wind, wave, and weather variables in forecast increments of 1 hour up to 5 days. Data is gridded on a sliding scale from 120 km down to sub-km resolution. Measurements are available over most of the world within 5 degrees of each pole, from the surface to 300mb.
WorldWinds’ data is commercially distributed over the XM satellite radio constellation through a product dubbed "Weather-at-Sea". The WorldWinds product was developed for commercial and scientific users; science applications include global long-term prediction and climate change, land-cover/ land-use change, and natural hazard issues.
