Cumulative GPP data of rice Arkansas at 500 meters resolution

This collection comprises geospatial and tabular datasets centered on the rice-growing regions of Arkansas. It includes: Rice cropping frequency data based on the USDA NASS Cropland Data Layer (2022). A raster layer (arkansasricecropintensity2020rice) for the years 2008-2020 Shapefiles for Arkansas counties and the state boundary (“ME”) Environmental variables including temperature and photosynthetically active radiation (PAR) from the NCEP reanalysis MODIS-derived 8-day daily composite indices: Enhanced Vegetation Index (EVI) and Land Surface Water Index (LSWI), at 500m resolution Gross Primary Productivity (GPP) modeled using the Vegetation Photosynthesis Model (VPM) Additionally, a rice production region shapefile delineates six distinct ecological zones—North Delta, Middle Delta, South Delta, Grand Prairie, White River, and West of Crowley’s Ridge—based on geographic and hydrological criteria defined in the Arkansas Rice Commodity Reports.
