Inputs for Baseline ParFlow-CONUS2 Simulations

The ParFlow-CONUS2 model is the second generation national ParFlow model. The ParFlow-CONUS2 domain covers the entire contiguous US and areas draining to it. The domain extent and projection are based off of the National Water Model Grid. Manual corrections were made along the coastline to get rid of cells that were water and to prune any orphan cells (i.e. cells attached to the domain only by a corner). You can learn more about the domain and the model on the HydroFrame website. The conus2_domain dataset contains all of the input fields for the model as well as additional pre and post processing files that can be useful for data analysis.

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.
