REGMEX computes local indices for each operational geomagnetic station (GMS) named K_gms and ΔH_gms. These indices are used to computes the Mexican K-index (Kmex) and the regional (Mexican) counterpart of planetary Dst-index (ΔHmex).

We publish two versions of our indices, the first one is an early (nowcast) version available in near real-time. Few weeks latter, we deliver a final (definitive) version of our indices.

Our data is available in monthly-file format on the links beside.
