AORC atmospheric forcing data across CAMELS US basins, 1980 - 2024

These data are atmospheric forcings from NOAA's Analysis of Record for Calibration (AORC 2024) summarized over the CAMELS catchments (Addor et al. 2017), however, the delineations over those CAMELS basins were updated by Andy Wood (2024) using the basin boundaries produced for the USGS GagesII effort (Falcone 2011).

Data collected using this repository code: https://github.com/jmframe/CIROH_DL_NextGen/tree/main/forcing_prep, which should be somewhat derivative of this: https://github.com/CIROH-UA/ngen-datastream/tree/main/forcingprocessor.

There are eight variables representing the meteorological conditions:
Total Precipitaion (APCP_surface) - Hourly total precipitation (kgm-2 or mm) for Calibration (AORC) dataset
Air Temperature (TMP_2maboveground) - Temperature (at 2 m above-ground-level (AGL)) (K)
Specific Humidity (SPFH_2maboveground) - Specific humidity (at 2 m AGL) (g g-1)
Downward Long-Wave Radiation Flux (DLWRF_surface) - longwave (infrared) radiation flux (at the surface) (W m-2)
Downward Short-Wave Radiation Flux (DSWRF_surface) - Downward shortwave (solar) radiation flux (at the surface) (W m-2)
Pressure (PRES_surface) - Air pressure (at the surface) (Pa)
U-Component of Wind (UGRD_10maboveground) - (west-east) - components of the wind (at 10 m AGL) (m s-1)
V-Component of Wind (VGRD_10maboveground) - (south-north) - components of the wind (at 10 m AGL) (m s-1)

The data include a timestamp from Coordinated Universal Time (UTC; AORC 2021).
