The data record spans from 1981 to 2013 using data from eight NOAA polar orbiting satellites: NOAA-7, -9, -11, -14, -16, -17, -18 and -19. The data are projected on a 0.05 degree x 0.05 degree global grid. This dataset is one of the Land Surface CDR Version 5 products produced by the NASA Goddard Space Flight Center (GSFC) and the University of Maryland (UMD). Improvements for Version 5 include using the improved surface reflectance data, correcting the data for known errors in time, latitude, and longitude variables, as well as improvements in the global and variable attribute definitions. The dataset is in the netCDF-4 file format following ACDD and CF Conventions. The dataset is accompanied by algorithm documentation, data flow diagram and source code for the NOAA CDR Program. This dataset provides scientific researchers a high quality Climate Data Record (CDR) of Leaf Area Index (LAI) and the Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) for detecting drought-stressed regions, forecasting agricultural yields, and forestry and crop management. LAI and FAPAR, two biophysical variables, characterize the canopy and photosynthetic activity of plants. The one-sided green leaf area per unit ground surface area describes the LAI data set. The fraction of the incoming solar radiation in the Photosynthetically Active Radiation spectral region that is absorbed by the plants defines the FAPAR data set. The LAI/FAPAR CDR produces a daily product on a 0.05 degree by 0.05 degree grid from 1981 to present derived from Advanced Very High Resolution Radiometer (AVHRR) sensors.
