These are definitely worth checking out. Can also try VHF-lo TV dxing and for amateur radio operators, 6m.
I recently learned about SNOTEL, which are a bunch of snow monitors by the USDA that use meteor scatter to report their readings. Freqs that I've found (not verified) for them are 40.67, 40.53, and 41.53 MHz. Supposedly BNSF railroad uses (or used?) meteor scatter on VHF-lo band for some stuff (44.58 MHz, allegedly).
And HamSCI has events around these peaks:
