Description:

  • summary: This dataset represents the output of the automated soil moisture mapping system for the state of Oklahoma, USA, as described in Ochsner et al. (2019; doi:10.1029/2018WR024535) and displayed at http://soilmoisture.okstate.edu/.
  • comment: The maps of soil volumetric water content (VWC) are generated using (1) in-situ soil moisture data from the Oklahoma Mesonet used in a regression kriging routine that incorporates (2) soil texture (percent sand) estimates from USDA-NRCS SSURGO and (3) an antecedent precipitation index computed from NOAA NWS Arkansas Red Basin River Forecast Center multisensor precipitation estimates. Each pixel is 800 by 800 meters, which is approximately the same area as one quarter section. The maps are valid at midnight local standard time (0600 UTC).
