Digital Meridian Spectrometer

Load and plot UAF Geophysical Institute Digital Meridian Spectrometer data from Poker Flat, with NetCDF3/4 auroral spectral measurements.

Load and plot UAF Geophysical Institute Digital Meridian Spectrometer data from Poker Flat Research Range. The software handles spectral data from a ground-based meridian scanning photometer that measures auroral emissions at multiple wavelengths, including 427.8 nm N2+, 486.1 nm H-beta, 520.0 nm [NI], 557.7 nm [OI], 630.0 nm [OI], and 670.0 nm N2. It supports both historical NetCDF3 format .PF files from 1983-2010 and current NetCDF4 format .NC files from 2011-present. The software provides data loading functions that return xarray.Dataset objects with time-elevation-intensity arrays, along with visualization capabilities including spectrograms and line plots. The library includes both Python and MATLAB interfaces.
