abstract: This dataset contains gridded daily surface reflectance and brightness temperatures derived from the Advanced Very High Resolution Radiometer (AVHRR) sensors onboard eight NOAA polar orbiting satellites: NOAA-7, -9, -11, -14, -16, -17, -18 and -19. Surface reflectance from AVHRR channels 1 and 2 (at 640 and 860 nm) are a NOAA Climate Data Record (CDR). The dataset spans from 1981 to 10 days before the present, and was processed from the AVHRR Global Area Coverage (GAC) Level 1b dataset. AVHRR GAC observations are packaged into data arrays with latitude and longitude dimensions of 3600 x 7200 covering the globe at 0.05 degree spatial resolution. 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). Other Land Surface CDR products include the Normalized Difference Vegetation Index (NDVI), Leaf Area Index (LAI) and Fraction of Absorbed Photosynthetically Active Radiation (FAPAR). Scientific improvements for Version 5 include updating to higher resolution ancillary data and more accurate approaches for BRDF correction, calibration, compositing, and QA. Version 5 also corrects the data for known errors in time, latitude, and longitude variables, as well as improves 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.
purpose: This dataset was produced to provide scientific researchers a high quality Climate Data Record (CDR) of land surface reflectance. Surface Reflectance provides a measure of the fraction of incoming solar radiation that is reflected from Earth's surface in two spectral ranges of the Advanced Very High Resolution Radiometer (AVHRR) sensors: red (around 640 nm) and the near infrared (around 860 nm). As a key variable, Surface Reflectance supplies the primary input for essentially all higher-level land surface geophysical parameters. The Surface Reflectance CDR delivers valuable surface information dating back to 1981 as a daily product on a 0.05 degree by 0.05 degree grid.
