New Global 1km Resolution Vegetation Index and Green Vegetation Fraction Products at NOAA

For the past several years, global 4km (0.036 degree) and regional (CONUS and environs) 1km (0.009 degree) resolution Vegetation Index (VI) and Green Vegetation Fraction (GVF) data have been produced by the NOAA-NESDIS Data Exploitation (NDE) project from the polar-orbiting Visible Infrared Imaging Radiometer Suite (VIIRS) instrument. The most recent upgrade to the data processing system that produces VIIRS VI and GVF will lead to the operational production of global 1km resolution data. Here we show some examples of 1km resolution VIIRS VI and GVF in parts of the globe separate from the CONUS-surrounding current regional data area, with comparisons to the currently operational 4km global data sets, demonstrating the improvement in the ability to resolve details of the land surface. Regions in South America, Asia, and Africa will be shown. Improvements include better resolution of coastlines and different types of land cover. The 1km global VI will be produced on daily rolling daily, weekly, and biweekly time intervals, and the 1km global GVF will be produced on daily rolling weekly time intervals. We expect the 1km global VI and GVF production to become operational by the end of 2024, with the data to be made available to any interested user through the NOAA CLASS system.
