# terndata.flux

This is a Python package to work with TERN eddy covariance flux data. It provides API methods to explore and access flux datasets from the TERN Ecosystem processes Flux tower, The library will enable users to access all Flux data from THREDDS/DAP server (i.e. dap.tern.org.au).

### Build
Buid the package wheel locally (docker required):
    
    make build

Build the API documentation (set a Github personal token in envvars first):

    make doc

To run unittests:

    make test

    OR
    
    Run the script below in Python virtual environment:
        ./ci-scripts/run-tests.sh

### Installation
Install from pypi:

    pip install terndata.flux


### API Methods
See the [API documentation](https://terndata-flux.readthedocs.io) generated from the code (see above).

### Getting started
The following examples are provided to help you get started, with sample output (as indicated by >>>) where appropriate:

```python
    import terndata.flux as flux 
    # Get sites where flux data is available
    flux.get_sites()
    >>> site           longitude   latitude  ...                start                  end                     geometry
