This Python package provides a set of tools for quality control (QC) of marine meteorological reports. Marine meteorological reports typically comprise latitude, longitude, time, and date as well as one or more marine meteorological variables often including, but not limited to sea-surface temperature, air temperature, dew point temperature, sea level pressure, wind speed and wind direction. Quality control is the process of identifying and flagging reports and variables within reports that are likely to be in gross error. It is important to note that QC checks do not (and cannot) identify all incorrect reports and they can also identify good reports as being erroneous.

You can install the package directly from pip:

pip install marine_qc

If you want to contribute, we recommend cloning the repository and installing the package in development mode, e.g.

git clone https://github.com/glamod/marine_qc
cd marine_qc
pip install -e .

This will install the package but you can still edit it and you don't need the package in your PYTHONPATH

You can install the package using uv package manager, this will add the library to your active environment:

uv add marine_qc

To develop the package using uv, the following will create a virtual environment, uv defaults to .venv:

git clone https://github.com/glamod/marine_qc
cd marine_qc
uv venv --python 3.12      # Create an environment with the recommended python version
source .venv/bin/activate  # Load the virtual environment (for bash or zsh)
uv sync
