List of geomagnetic disturbances 2010-2022

List of geomagnetic disturbances (GMDs) using SuperMAG 1 second data stations between 2010 and 2022

Each line had the format of station ID, year, month, day, UT, GMD value (nT/10sec), GMD Field direction, Algorithm Flag, Wave frequency (Hz), Error on wave frequency (Hz), Y if Gaussian fit worked N otherwise.

Algorithm flag is: B:Bad, D:Doubtful, W:Wave related, G:Good/Non wave related.

This is the GMD list created with a threshold of 50 nT/10 sec generated using the method outlined in:
