The land aerosol optical depth dataset in Southwest China (Sichuan, Chongqing, Yunnan, Guizhou) is a grid level 2 product MCD19A2 based on the Multi-angle Implementation of Atmospheric Correction (MAIAC) of MODIS Terra and Aqua. The spatial resolution is 1km, and the temporal resolution is 1 day; The time range is from February 28, 2000, to September 6, 2022. The data is in TIF format. The first seven digits of its name are "SW.AOD." followed by a date identifier of year+day. For example, "2022.001" means the first day of 2022, and so on. The coordinate system of data is GCS_ Unknown_ datum_ based_ upon_ the_ custom_ spheroid。
Data naming format:
The naming rule is "SW.AOD.YYYY.DDD.tif", where YYYY represents the year and DDD represents a particular day of the year.
Data reading mode:
This dataset is in the format of a standard geospatial TIF file, which can be read by common ArcGIS, ENVI, PCI, and other professional software.
