hi, i am trying to find what fraction of the solar intensity is at
633nm with a 1 nm bandwidth.  there has got to be tables somewhere,
but i have looked all over with no success.  i need the actual data
for inner atmosphere, and not the blackbody spectrum.  Question:  what
is the solar intensity from 632.5-633.5nm at sea level?

thanks

ok,
I am not certain of the answer but go have a look there for
explanations http://rredc.nrel.gov/solar/spectra/am1.5/
and there for the table you might be looking for
http://rredc.nrel.gov/solar/spectra/am1.5/ASTMG173/ASTMG173.html

for the conversions and final calculation, you're more likely to do it
right than me.

that was exactly what i was looking for!  you are awesome.  thank you
so much.  it's like really intelligent people are waiting for dumb
people like me to post questions.  i cant believe how fast i get
responses, and correct ones at that!  i'm new to this google answers
thing, please excuse my excitement.
