AI-generated Key Takeaways
-
This MODIS dataset (MYD09A1) has been replaced by a newer version (MODIS/061/MYD09A1).
-
It provides an estimate of surface spectral reflectance, corrected for atmospheric effects, at a 500-meter resolution.
-
Data is collected globally, in an 8-day gridded format, from 2002-07-04 to 2017-03-22.
-
Each pixel represents the best observation during an 8-day period based on criteria like coverage, view angle, and cloud presence.
-
The dataset includes reflectance values for bands 1-7, quality assessment, day of the year, and solar/view/zenith angles.

Description
The MODIS Surface Reflectance 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. Low-level data are corrected for atmospheric gases and aerosols, yielding a level-2 basis for several higher-order gridded level-2 (L2G) and level-3 products.
MYD09A1 provides Bands 1-7 at 500-meter resolution in an 8-day gridded level-3 product in the Sinusoidal projection. Each MYD09A1 pixel contains the best possible L2G observation during an 8-day period as selected on the basis of high observation coverage, low view angle, the absence of clouds or cloud shadow, and aerosol loading. Science Data Sets provided for this product include reflectance values for Bands 1-7, quality assessment, and the day of the year for the pixel along with solar, view, and zenith angles.
