Data-Driven Drought Prediction Project Model Inputs for Select U.S. Geological Survey Streamgage Basins: Monthly Climate Metrics from North American Multi-Model Ensemble (NMME) Phase 2, 1982 - 2023 (ver. 2.0, July 2025)

These tabular data sets represent monthly meteorological metrics processed from North American Multi-Model Ensemble (NMME) for the hindcast (1982-2011) and forecast (2011-2023) periods of record and compiled for the spatial component of select United States Geological Survey stream gage basins (Staub and others, 2023). Flowline reach catchment information characterizes data at the local scale using the python tool set called gdptools (McDonald, 2021). The following monthly meteorological metrics were processed: reference temperature (degree Celsius), and total precipitation (millimeters) for forecast periods of 15, 45, 75, and 105 days (0.5 to 3.5 months).
