AI Thread Summary
A reliable tabulation of the Earth's atmospheric opacity as a function of wavelength from 100nm to 1 micron is sought, with a preference for models like the US Standard Atmosphere. Resources such as LOWTRAN, MODTRAN, and HITRAN are suggested as potential references. Specific links to these models and related figures are provided for further exploration. However, there is a noted lack of clarity regarding the column representations in the LOWTRAN data, indicating a need for additional information on interpreting these results.

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,

Natski

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/software/lowtran/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?

Thread '(Unprecedented?) Cluster of earthquakes in Greek islands'

These last days, there is a seemingly endless cluster of rather powerful earthquakes close to the islands of Santorini, Amorgos, Anafi, and Ios. Remember, this is a highly volcanically active region, Santorini especially being famous for the supervolcanic eruption which is conjectured to have led to the decline of the Minoan civilization: https://en.m.wikipedia.org/wiki/Minoan_eruption To grasp the scale of what is happening, between the 26th of January and the 9th of February, 12000...
