For Geophysical Institute's Poker Flat Digital Meridian Spectrometer, which uses NetCDF

![example of PF-DMSP data](src/dmsp/tests/demo.png)

This library is also usable from Matlab, as seen in `dmsp.m`.

## Data sources

* 2011-present: ftp://optics.gi.alaska.edu/PKR/DMSP/NCDF/

* 1983-2010 (NetCDF 3 .PF files): http://optics.gi.alaska.edu/realtime/data/msp/pkr   This link was good for years and we used this data, but in late 2018 it stopped working.

* [other dates](http://optics.gi.alaska.edu/realtime/data/archive/PKR_MSP_X/)

* FTP: ftp://optics.gi.alaska.edu/PKR/DMSP

Install:

```sh

python -m pip install -e .

```

[LoadMSPdata.py](./LoadMSPdata.py) creates many plots.

Use as a Python module:

```python

import dmsp

dat = dmsp.load('~/data/myfile.PF')

```

which returns [xarray.Dataset](https://docs.xarray.dev/en/stable/generated/xarray.Dataset.html)
