The NG-IDF: Crop datasets cover more than 200,000 sites at approximately 6 km resolution in the years 1951–2013 across the CONUS for the Crop land use land cover (LULC). These [daily time series + annual maximum] datasets provide information on extreme hydrological events and their associated hydrometeorological drivers at a continental scale. They include 1) daily time series of precipitation (P), throughfall (TF), water available for runoff (W), and snow water equivalent (SWE); 2) annual maximum time series of P, W, TF, snowmelt, rain-on-snow (ROS); and 3) NG-IDF curves and their uncertainties. See the "Crop_readmefirst.txt" file for details.
