Title: Will Sahara / Atlantic Dust Cloud affect propagation?
Post by: ThaDood on June 23, 2020, 2046 UTC
What is this dust cloud going to do to affect RF on various FREQ's?    https://www.accuweather.com/en/weather-news/abnormally-large-dust-cloud-making-5000-mile-trek-across-atlantic/761708
This does not answer that.

My assumption is that very small frequency -- microwave and millimeter wave, etc. -- propagation could be affected, maybe even severely if the storm/dust were intense enough... but I can't really find anything that suggests serious propagation effects below those frequency ranges. Would be nice to know for certain though.

Well, I'm wondering if it could cause a reflective affect, like Tropo, on VHF and UHF? Hmmmmmmm???
