The GLASS photosynthetically active radiation absorption ratio (FAPAR) product is consistent with the LAI V6 product, and is obtained by using satellite data and existing FAPAR and LAI products to invert the GLASS-FAPAR product. The spatial range of the GLASS-FAPAR product is the global land surface, with a spatial resolution of 250m and a temporal resolution of 8 days. The output format of GLASS-FAPAR product is HDF-EOS standard format, which includes two datasets: photosynthetically active radiation absorption ratio and quality identification label.
This dataset collected data from three bands, H25v04, H25v05, and H26v05, in Gansu Province from 2000 to 2021.

GLASS FAPAR is approximately equal to subtracting the transmittance of PAR throughout the entire tree crown, which can be calculated from GLASS LAI products and other information. This algorithm can effectively estimate the FAPAR value that is physically consistent with the product of LAI. The GLASS FAPAR product from MODIS data is an instantaneous value at 10:30 am local time, which is very close to the daily average PAPAR.
Good data quality
