How often does MODIS acquire data and what are the characteristics of the data?
Each MODIS sensor has a wide field of view (2,330 kilometers) that allows the sensor to image the Earth on a daily basis at latitudes greater than 30 degrees and every 1 to 2 days at latitudes less than 30 degrees. MODIS image data are acquired in 36 co-registered spectral bands at moderate spatial resolutions (250, 500, and 1,000 meters). Thermal information is collected at 1,000-meter spatial resolution and is collected twice daily by each sensor (one daytime and one nighttime observation) in the mid to high latitudes.
