wera2netcdf 0.0.4

A utility to convert WERA total ASCII files into CF NetCDF files.

# wera2netcdf [](https://travis-ci.org/axiom-data-science/wera2netcdf)

Converting WERA Total ASCII files (the final total current speed and direction
of the combined radial data) into CF NetCDF files.

## Installation

```
# pip
$ pip install wera2netcdf

# conda
$ conda install -c ioos wera2netcdf
```

## Usage

```python
In [1]: from wera2netcdf import WeraAsciiTotals
In [2]: w = WeraAsciiTotals('totals.txt')
In [3]: w.is_valid()
Out[3]: True

# Pandas dataframe of the data
In [4]: w.data.head()
Out[4]:
