# Tag for ionospheric/propagation conditions?

I asked this question which I tagged 'ionosphere' (which didn't previously exist). User Mike added the tag propagation, which has one other question tagged. As far as HF goes, these tags are probably synonymous, but ionosphere is a more abstract way of describing the concept (so probably less useful).

Is there any reason why an ionosphere (or similar) tag might be needed, separate from propagation?

• It also opens up the possibility for both discussions relating to the ionosphere without being directly related to propagation ("what is the impact of the ionosphere on upper UHF range signals?") as well as non-ionospheric propagation. There isn't one yet, but I think we should anticipate a line-of-sight tag too. – user Oct 23 '13 at 12:58
