SpaceWx, a division of Space Environment Technologies, has a strategic vision to provide customers with the world's premier space weather information and forecasting technologies. Our vision is based on combining leading-edge space physics models with aerospace applications to accurately characterize the space environment. We partner with government agencies, university researchers, and industry leaders to provide applied-research solutions to adverse solar-terrestrial effects. SpaceWx core expertise is based upon the accurate specification of solar irradiance variations. Along with our partners, we actively conduct research and develop product opportunities, combining solar irradiances with research-operational models for space weather forecasts and with commercial products for space operations. SpaceWx supports space science and engineering research by providing internet download access to research-grade solar irradiance models including SOLAR2000, an empirical model representing the 1-1,000,000 nm solar spectrum at 1 nm resolution. The SpaceWx web site officially hosts access to the draft ISO solar irradiance standard WD 21348. For access to SpaceWx, please link to http://SpaceWx.com. W.
