GINA offers real-time reception, processing, and delivery of imagery and information products from a variety of polar-orbiting satellites. Currently, GINA receives real-time data from three places: NASA’s EOS Terra and Aqua Moderate Resolution Imaging Spectroradiometer; MODIS since August 2001; and NOAA’s operational satellites carrying the Advanced Very High Resolution Radiometer (AVHRR) since August 1993. Our high-latitude locality affords enhanced reception opportunities for the polar-orbiting satellites tracked by GINA. On average, GINA receives about 20 AVHRR passes and 15 MODIS passes per day.

GINA offers customized image processing, algorithm development, and delivery of data in near-real-time as well as an extensive archive of MODIS and AVHRR images from all over the western Arctic. GINA also houses a growing Landsat archive. In addition, we are currently gathering other collections held by the USGS, University of Alaska, federal agencies, and private sector firms.

The following animation is two days of AVHRR images from late June 2007. These 151 scenes are are a typical 48-hour AVHRR data flow through GINA from the NOAA/NESDIS FCDAS stations in Fairbanks and Barrow, and from GINA's own stations on the UAF campus.
