Hi all,

Does anyone know of a reliable tabulation of the opacity of the Earth's atmosphere (for example at zenith distance zero) as a function of wavelength from 100nm to 1 micron? Obviously the opacity varies with different conditions but something like a US Standard Atmosphere model would suffice for my needs.

Thanks in advance,

Have you looked at LOWTRAN/MODTRAN/HITRAN?

Or is something like this good enough:

Ah yes this looks very useful, thanks. Looking at http://www1.ncdc.noaa.gov/pub/softwa...an/lowtran7.16 as an example, there does not seem to be a key as to what the columns actually mean. Do you know what each column represents here?
