The HN community knows a lot, but not about Earth science. (Although there are some astrophysicists here.) I have a PhD in a statistical field, and I work with PhD statisticians analyzing Earth science data. When things about interpreting results, or choosing appropriate data, come up...we talk to a domain scientist. So I’d suggest thinking about a way to do that, if you care about the validity of your conclusions. And, as I suggested earlier, a literature review, starting with the overview reports.
