pyisd

Reads NOAA Integrated Surface Database (ISD) data.

Installation

pip install isd

Usage

There is a simple command line interface. The isd record command prints a single record in JSON format:

isd record 720538-00164-2021

The Python API allows reading compressed and uncompressed ISD files:

import isd.io

with isd.io.open("isd-file") as records_iterator:
    records = list(records_iterator)

There is currently no parsing of the additional_data section, but all mandatory fields are parsed out into appropriately-typed fields on a Record.

Development

Install the development requirements and the package in editable mode:

pip install -e '.[dev]'

To run the unit tests:

pytest

Release

To cut a new release of pyisd (assuming you have the appropriate permissions):

1. Create a new branch, e.g. release/v0.1.4.
2. Update pre-commit hooks: pre-commit autoupdate
3. Update the CHANGELOG and pyproject.toml.
4. Open a pull request with the changes.
5. Merge the pull request once all required checks pass.
6. Create an annotated tag, e.g. git tag -a v0.1.4.
7. Push the annotated tag to github. This will trigger a new pypi release.
