xNRL helps you read NRL NWP output into xarray Datasets nested within Pandas DataFrames.

Install

xNRL requires numpy, pandas, and xarray.

Install with pip

pip install xnrl

Clone and install with pip

git clone https://github.com/U-S-NRL-Marine-Meteorology-Division/xnrl.git

pip install -e .

The -e makes the code editable.

You can update the code with

cd xnrl
git pull origin main

Install with Conda

Copy the environment_xnrl.yml file and create the Conda environment.

conda env create -f environment_xnrl.yml

Note: This only installs the current main branch and does not let you edit the code. You can update xnrl (and all packages in the environment) with

conda env update -f environment_xnrl.yml

Examples

import xnrl

# Load COAMPS flatfiles into an xarray Dataset
fp = '<path>/*pre*00120*'
ds = xnrl.open_dataset(fp, model='COAMPS')
