Alisal Fire in California
Images captured on 11 and 12 October 2021, by the MODIS instrument, aboard the Aqua and Terra satellites.
False-color corrected reflectance images (Bands 7-2-1) of the Alisal Fire, west of Santa Barbara in California on 11 and 12 October 2021. These images were acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS), aboard the Terra satellite and the Aqua satellite. These images are a false color Red-Green-Blue (RGB) composite where Red is Band 7, Green is Band 2, and Blue is Band 1. This combination is most useful for distinguishing burn scars from naturally low vegetation or bare soil and enhancing floods. Vegetation appears green, water is black and burn scars are red. The bright red areas represent the actively burning fire front.
