Unique categories of geomagnetic activity 2010–2017

<p>This is the dataset generated as described in Coxon et al. (2023): "Extreme Birkeland currents are more likely during geomagnetic storms on the dayside of the Earth".</p> <p>Please cite the following papers when using this data:</p> <ul> <li>Forsyth et al. (2015): https://doi.org/10.1002/2015JA021343</li> <li>Walach & Grocott (2019): https://doi.org/10.1029/2019JA026816</li> <li>Coxon et al. (2023):  https://doi.org/10.1029/2023JA031946</li> </ul> <p>This dataset is a list of timestamps at 1-minute cadence from 00:00 UT on 2010-01-01 to 23:59 UT on 2017-12-31. Each timestamp is assigned an integer category where the integer is defined as follows:</p> <ul> <li>0. The timestamp is during quiet times</li> <li>1. The timestamp is during storm times</li> <li>2. The timestamp is during a quiet-time substorm</li> <li>3. The timestamp is during a storm-time substorm</li> </ul>
