National Land Data Assimilation Product V2 - Water Year 1985

The NLDAS2 forcing dataset at 1km resolution and a 1 hour time step. This dataset was used to force the conus1_baseline_85 simulation (https://hf-hydrodata.readthedocs.io/en/latest/gen_conus1_baseline_85.html). This dataset is bilinearly interpolated to the ParFlow-CONUS1 grid. The original NLDAS2 dataset can be found here (https://ldas.gsfc.nasa.gov/nldas).

accessRights Users must create a HydroFrame API account and register their PIN before using the hf_hydrodata package. If it's your first time using this package you will need to sign up for a HydroFrame account on the HydroFrame Signup Page (https://hydrogen.princeton.edu/signup; note: this only needs to be done once). Visit our HydroFrame PIN Page (https://hydrogen.princeton.edu/pin) to create a 4-digit PIN. After creating your PIN, you must register that PIN on the machine that you intend to use.
