MODIS/Terra+Aqua Land Surface BRF Daily L2G Global 500m and 1km SIN Grid NRT
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/modis/mcd19a1n.nrt.061
The MODIS Near Real Time (NRT) Combined Terra and Aqua Multi-Angle Implementation of Atmospheric Correction (MAIAC) Land Surface Bidirectional Reflectance Factor (BRF) gridded Level 2 product (MCD19A1N) produced daily at 500 meter (m) and 1 kilometer (km) pixel resolutions.
Description
The MCD19A1N product is corrected for atmospheric gases and aerosols using a new MAIAC algorithm that is based on a time series analysis and a combination of pixel- and image-based processing.
The MODIS MAIAC Land Surface BRF products provide an estimate of the surface spectral reflectance as it would be measured at ground-level in the absence of atmospheric scattering or absorption. The Version 6.1 Level-1B (L1B) products have been improved by undergoing various calibration changes that include: changes to the response-versus-scan angle (RVS) approach that affects reflectance bands for Aqua and Terra MODIS, corrections to adjust for the optical crosstalk in Terra MODIS infrared (IR) bands, and corrections to the Terra MODIS forward look-up table (LUT) update for the period 2012 - 2017.

A polarization correction has been applied to the L1B Reflective Solar Bands (RSB).
