A suite of tools for working with BUFR
Project description
BUFR Tools
A suite of utilities and scripts to forge a BUFR file, or decode one.
Installation
bufrtools is available in the axiom-data-science channel on anaconda.org.
conda install -c axiom-data-science bufrtools
Development
It is advisable to use conda for development and usage of this project, although it's not strictly necessary. This README assumes the use of conda, however.
To install the environment:
conda env create -f environment.yml
Usage
Encoding Wildlife Computers netCDF Profiles
The wildlife_computers module provides a command-line interface for encoding a Wildlife Computers' netCDF profile dataset as a BUFR message.
Usage:
python bufrtools/encoding/wildlife_computers.py -o <output bufr file> <netCDF path>
The following table contains the expanded sequence of descriptors for temperature salinity profiles and trajectories originating from marine animal tags.
The source of this information is the published Manual on WMO Codes.
