Aerosol Optical Depth/Thickness Datasets
MODIS
Moderate Resolution Imaging Spectroradiometer (MODIS) instruments are aboard NASA’s Terra and Aqua platforms and provide estimates about aerosol optical depth. Terra's orbit is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon.
GIBS will be expanding the data range and palette of the MODIS Aerosol Optical Depth products.
NASA Worldview added four layers from the Aerosol Robotic Network (AERONET) program to provide ground-based measurements of aerosol optical depth (AOD) and Angstrom parameter.
Scientists develop routine service for wildfire detection in the continental United States with a latency of less than 60 seconds.
