Overview

True color images are derived from the Moderate Resolution Imaging Spectroradiometer
(MODIS) instrument, which files onboard NASA’sTerra and Aqua satellites. MODIS has 36
distinct spectral bands, with wavelengths ranging from 0.405 to 14.385 µm. True color images
look like photographs, but they are actually created using MODIS’s red, green, and blue bands...

ECHO indexes two versions of "MODIS True Color" (AKA MOD02QKM or MODIS/Terra Calibrated Radiances 5-Min L1B Swath 250m V005): one archived science quality product and one near-real-time (NRT) product. ECHO has imagery links for data in the science archive from 2000 to 2010.
