The MODIS instrument operated on both the Terra and Aqua spacecraft during STAR.  The viewing swath width was 2,330 km and viewed the entire surface of the Earth every one to two days. Its detectors measured 36 spectral bands between 0.405 and 14.385 µm, and it acquired data at three spatial resolutions -- 250m, 500m, and 1,000m.

Along with all the data from other instruments on board the Terra spacecraft and Aqua Spacecraft, MODIS data were transferred to ground stations in White Sands, New Mexico, via the Tracking and Data Relay Satellite System (TDRSS). The data were then sent to the EOS Data and Operations System (EDOS) at the NASA Goddard Space Flight Center. The Level 1A, Level 1B, geolocation and cloud mask products and the Higher-level MODIS land and atmosphere products were produced by the MODIS Adaptive Processing System (MODAPS), and then were parceled out among three DAACs for distribution. MODIS Level 1 and atmosphere products are available through the NASA Low-Altitude Air Defense System (LAADS) web site. For further information see: https://ladsweb.modaps.eosdis.nasa.gov/

The MODIS Level 1B 1km earth-view (EV) product (visible satellite imagery) over southern Baffin Island were downloaded for the 2007 Autumn STAR IOP period.
