UV radiation

[cathryn_meyer@yale_edu]

Is there a way to change incoming UV radiation, without changing other wavelengths as well?

Thanks,
Cathy

My friend Ultraviolet radiation is a specific part of the sun's entire spectrum of wavelengths UV radiation can be further sub-divided into three parts. UV-C is characterized by wavelengths less than 280 nm. Although highly dangerous to plants and animals, this part of the UV spectrum is completely absorbed by stratospheric ozone and does not reach the earth's surface. UV-B ranges in wavelengths between 280 and 320 nm.

Hi Cathy,

You can change the spectral distribution of solar radiation fairly
easily by altering the first nine elements of the frcsol array
in radsw.F90.
This is the fraction of solar radiation within a spectral band.
The wavmin and wavmax variables contain the spectral
boundaries (in microns) to guide your re-allocation.
Bands 1-7 are UV and 8 and 9 are visible.
You can reapportion energy among these bands as you wish so long as the net change is zero.

Good luck,
Charlie
