The MODIS/Terra Atmosphere Aeronet Subsetting Product (MODARNSS) consists of MODIS Atmosphere and Ancillary Products subsets that are generated over a number of Aerosol Robotic Network (AERONET) sites. These sites comprise of sites of automatic tracking Sun photometers/sky radiometers located all over the world. The process of generating cutouts involves locating and identifying a subset of sites taken from a global AERONET that are within the spatial coverage of a 5 minute Level 2 MODIS granule and extracting 0.5 x 0.5 degree cutouts. The MODARNSS data set consists of subsets for around 180 AERONET sites around the globe. There is one file per site with 55 Science Data Sets (SDS) such as at-aperture radiances for 36 discrete MODIS bands, Cloud Mask, and Water Vapor, etc.
