Extended UWP for exotic atmospheres

[JBHemlock]

I'm in the process of developing a chlorine-breathing race that I'm placing out in the Far Frontiers sector (in the Federation of Alsas, which I've never found any information on). From the Imperium's point of view, their homeworld would have an atmosphere of A, but it would be convenient to have a chlorine-centric UWP for the chlorine-breathers to use (i.e.: they've colonized and terraformed world X, but it's still tainted, so they'd call it an atmosphere of 7-Cl or something).

Has anyone worked out something like this? I'm probably just going to make notes of the atmospheres of their planets and go from there, but I'm curious if anyone else has already solved this problem.

If you don't need it to be absolutely a single digit (e.g. for computer data-entry purposes), what I do is put a subscript on the A, B, or C atmosphere type that is the "equivalent" atmosphere density.

e.g. A Dense CO₂ atmosphere would be A₈.

Or, if you wanted to expand it a little more, create a code-letter for a standard N₂/O₂ atmosphere (and other code-letters for other typical atmosphere compositions/mixes), and then do the same type of subscripting (so that all atmosphere codes are a letter with a subscript - including density and/or taint code).

EDIT: Or you could reverse the above, and use the number code for the atmosphere (density/taint), and add a subscript defining the atmosphere composition.

I agree with above, it depends a lot on how much you need to make it fit into standard UWP format, within which these are all simply variations of Atmo type A.

If you really want it from the POV of the other breathers, they would probably call it a 6 (standard) or 7 (standard tainted).

Beyond that, I haven't gotten much into standardizing variant atmospheres. If it is important enough for me to have determined exactly what kind of A-B-C Atmo is present, then I have a set of world notes with that info included.

I think the more standard way to handle extended attributes like this is un a UWP or SEC file format would be to follow the example of the population multiplier digit. A similar digit that indicates atmospheric pressure would be really handy

However a subscript is a useful way to visually represent the data, e.g. on a map and could also be used to indicate population multipliers.
