TREx Spectrograph

The Meridian Imaging Spectrographs obtain a full auroral spectrum along a magnetic meridian, from which keograms (and other data products) of individual auroral emissions (e.g., 630 nm) can be obtained. As well, one can calculate ratios between different emissions, and identify the presence of the continuum emission.

Dataset Detailed Descriptions

TREX_SPECT_PROCESSED_V1

The primary dataset used by the analysis support software, and the dataset that most users utilize. These files are 1-hour HDF5 files containing calibrated and de-smiled data.
