MODIS instruments (Moderate-Resolution Imaging Spectroradiometer) on-board Terra and Aqua satellites provide a global view of earth on a daily basis since 1999 and 2002. With a resolution up to 250m per pixel and 36 spectral bands, MODIS images can produce stunning view of earth.
Only data produced after May 2012 are available on-line.
Late 2015 (Nov. 25), VIIRS imagery from SUOMI NPP spacecraft was also added to available global and daily dataset.
Data are available 3-4 hours after acquisition. if the map appears black, it means the data are not yet available.
Terra satellite local equatorial crossing time is approximately 10:30 a.m. in a descending orbit.
Aqua satellite local equatorial crossing time is approximately 1:30 p.m. in an ascending orbit.
SUOMI NPP satellite local equatorial crossing time is approximately 1:30 p.m. in an ascending orbit.
