In addition to in-house generated products, several MODIS products including cloud top pressure, a cloud mask, lifted index and cloud phase are obtained from the University of Wisconsin and distributed to NWS offices.
Specifically, SPoRT uses single bands from the visible and infrared to provide high resolution imagery to its NWS partner offices and multiple bands to generate products such as color composite imagery, land surface temperature, and a cloud mask.
Additional real-time products have been generated as part of SPoRT's activities with algorithms developed by SPoRT scientists. A few of these algorithms have been adapted for real-time applications as part of the IMAPP software available to Terra/Aqua direct broadcast ground stations, and some of these real-time EOS products are the ones used by SPoRT.
These products are derived at the various NASA DAACs using MODIS science team algorithms. SPoRT obtains this imagery from the University of Wisconsin (UW) and the University of South Florida (USF) direct broadcast stations and provides selected products to NWS Forecast Offices formatted for display in their native AWIPS system.Ī wealth of geophysical parameters describing the Earth's surface (land and ocean) and atmosphere (including clouds) are derived from MODIS imagery by the EOS science team in support of NASA's global climate research projects. Real-time MODIS imagery is available from a number of direct broadcast ground stations throughout the world. The MODIS instrument acquires data in 36 spectral bands at resolutions of 1 km, 500 m, and 250 m, allowing for the retrieval of atmospheric, surface, and cloud properties at high resolutions. Terra's orbit crosses the equator at 10:30 am and pm, while Aqua's passes are at 1:30 am and pm, together providing up to 4 passes per day, with global coverage every 1 -2 days. MODIS (Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard both the Terra and Aqua NASA EOS satellites.
