The most recent link I have for reanalysis data will only plot maps up to 2015. Is there an updated link? https://psl.noaa.gov/cgi-bin/data/composites/plot20thc.v2.pl
Would anyone be interested in having a subforum for space weather discussions? I had friends asking me about a recent geomagntic storm and the data out there is sparse. I would love to read some expertise on the topic.
