**Herbie** is a python package that downloads recent and archived numerical weather prediction (NWP) model output from different cloud archive sources. **Its most popular capability is to download HRRR model data.** NWP data in GRIB2 format can be read with xarray+cfgrib. Much of this data is made available through the [NOAA Open Data Dissemination](https://www.noaa.gov/information-technology/open-data-dissemination) (NODD) Program (formerly the Big Data Program) which has made weather data more accessible than ever before.

Herbie helps you discover, download, and read data from:
- [High Resolution Rapid Refresh (HRRR)](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/hrrr.html) | [HRRR-Alaska](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/hrrrak.html)
- [Rapid Refresh (RAP)](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/rap.html)
- [Global Forecast System (GFS)](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/gfs.html)
- [Global Ensemble Forecast System (GEFS)](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/gefs.html)
- [ECMWF Open Data Forecast Products](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/ecmwf.html)
- [North American Mesoscale Model (NAM)](https://github.com/blaylockbk/Herbie/blob/main/docs/user_guide/_model_notebooks/nam.ipynb)
- [National Blend of Models (NBM)](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/nbm.html)
- [Rapid Refresh Forecast System - Prototype (RRFS)](https://herbie.readthedocs.io/en/latest/user_guide/_model_notebooks/rrfs.html)

# 📓 [Herbie Documentation](https://herbie.readthedocs.io/)

## Installation

The easiest way to instal Herbie and its dependencies is with [Conda](https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html) from conda-forge.

```bash
conda install -c conda-forge herbie-data
```


You may also create the provided Conda environment, **[`environment.yml`](https://github.com/blaylockbk/Herbie/blob/main/environment.yml)**.

```bash
# Download environment file
wget https://github.com/blaylockbk/Herbie/raw/main/environment.yml

# Modify that file if you wish.

# Create the environment
conda env create -f environment.yml

# Activate the environment
conda activate herbie
```

Alternatively, Herbie is published on PyPI and you can install it with pip, _but_ it requires some dependencies that you will have to install yourself:

- Python 3.8 to 3.11
- cURL
- [Cartopy](https://scitools.org.uk/cartopy/docs/latest/installing.html), which requires GEOS and Proj.
- [cfgrib](https://github.com/ecmwf/cfgrib), which requires eccodes.
- _Optional:_ wgrib2
- _Optional:_ [Carpenter Workshop](https://github.com/blaylockbk/Carpenter_Workshop)

When those are installed within your environment, _then_ you can install Herbie with pip.

```bash
# Latest published version
pip install herbie-data

# ~~ or ~~

# Most recent changes
pip install git+https://github.com/blaylockbk/Herbie.git
```

## Capabilities

- Search for model output from different data sources.
- Download full GRIB2 files.
- Download subset GRIB2 files (by grib field).
- Read data with xarray.
- Read index file with Pandas.
- Plot data with Cartopy (very early development).

```

```python
from herbie import Herbie

# Herbie object for the HRRR model 6-hr surface forecast product
H = Herbie(
  '2021-01-01 12:00',
  model='hrrr',
  product='sfc',
  fxx=6
)

# Look at file contents
H.inventory()

# Download the full GRIB2 file
H.download()

# Download a subset, like all fields at 500 mb
H.download(":500 mb")

# Read subset with xarray, like 2-m temperature.
H.xarray("TMP:2 m")
```

## Data Sources

Herbie downloads model data from the following sources, but can be extended to include others:

- [NOMADS](https://nomads.ncep.noaa.gov/)
- [NOAA Open Data Dissemination Program (NODD)](https://www.noaa.gov/information-technology/open-data-dissemination) partners (i.e., AWS, Google, Azure).
- [ECMWF Open Data}(https://www.ecmwf.int/en/forecasts/datasets/open-data)Azure storage
- University of Utah CHPC Pando archive
- Local file system

## History

During my PhD at the University of Utah, I created, at the time, the [only publicly-accessible archive of HRRR data](http://hrrr.chpc.utah.edu/). Over 1,000 research scientists and professionals used that archive.

<blockquote><cite>
<p style="padding-left: 22px ; text-indent: -22px ;"> Blaylock B., J. Horel and S. Liston, 2017: Cloud Archiving and Data Mining of High Resolution Rapid Refresh Model Output. Computers and Geosciences. 109, 43-50. <a href="https://doi.org/10.1016/j.cageo.2017.08.005">https://doi.org/10.1016/j.cageo.2017.08.005</a></p>
</cite></blockquote>

In the later half of 2020, the HRRR dataset from 2014 to present was made available through the [NODD Program](https://www.noaa.gov/information-technology/open-data-dissemination) (formerly NOAA's Big Data Program). Herbie organizes and expands my original download scripts into a more coherent package with the extended ability to download data for other models from many different archive sources.

I originally released this package under the name “HRRR-B” because it only worked with the HRRR dataset; the “B” was for my first-name initial. Since then, I have added the ability to download RAP, GFS, ECMWF, GEFS, RRFS, and others with potentially more models in the future. Thus, this package was renamed **_Herbie_**, named after one of my favorite childhood movie characters.

The University of Utah MesoWest group now manages a [HRRR archive in Zarr format](http://hrrr.chpc.utah.edu/). Maybe someday, Herbie will be able to take advantage of that archive.
