Description
DSCOVR_EPIC_L2_MAIAC_01 is the DSCOVR EPIC L2 Multi-Angle Implementation of Atmospheric Correction (MAIAC) Atmospheric Correction Version 1 data product. Data collection for this product is ongoing. Level 2 Multi-Angle Implementation of Atmospheric Correction (MAIAC) product contains atmospherically corrected spectral bidirectional reflectance factors (BRF, or surface reflectance) and bidirectional reflectance distribution function (BRDF) represented by 3 parameters of the Ross-Thick Li-Sparse model. It also provides several atmospheric quantities including cloud mask and aerosol optical depth (AOD) required for atmospheric correction. The parameters are distributed at 10 km sinusoidal grid and 1 to 2-hour temporal frequency. The atmospherically corrected surface reflectance and BRDF are fundamental quantities for climate modeling and vegetation studies. They are also important input to the Deep Space Climate Observatory (DSCOVR) Earth Polychromatic Imaging Camera (EPIC) Vegetation Earth System Data Record (VESDR) product. Due to high temporal and full disk global coverage, MAIAC EPIC AOD is a useful complementary dataset to MODIS and VIIRS global aerosol products.
