NCAR/ACD TUV: Tropospheric Ultraviolet & Visible Radiation Model
Entry ID: UCAR_TUV
Abstract: The Tropospheric Ultraviolet-Visible Model (TUV) model is used over
the wavelength range 121 - 750 nm, for calculating the spectral
irradiance, the spectral actinic flux, photodissociation coefficients
(J-values), and biologically effective irradiance (dose rates, doses).
The code has a number of features including
- separate direct and diffuse contributions,
- easy loading of weighting ... functions,
- variable wavelength and altitude grids, surface
- temperature and pressure dependence for selected J-values,
- absorption by oxygen ozone, and sulfur dioxide,
- scattering by air, clouds, and aerosols (Rayleigh and Mie),
- interchangeability of radiative transfer schemes,
- improved treatment of twilight (pseudo-spherical approximation)
- flexible looping through specified conditions,
- extensive in-code documentation.
This manuscript describes in some detail the driver program that is
likely of greatest interest to first-time users of the model. Some
example calculations are also given, as is some code documentation.
The code is written in standard FORTRAN 77 operating within a UNIX
environment. Conversion to other operating systems has been achieved
(e.g., McIntosh, Windows 95/98/NT), though some convenience may be
lost (e.g., the use of Makefiles). The code may be obtained from the
web site and is packed as a single tape archive (tar) file.
Suggestions for improvements and notification of possible code errors
are welcomed, and should be sent to email@example.com. Updates in input
data (e.g., extraterrestrial flux, cross sections and quantum yields,
action spectra, etc.) will be incorporated in future versions, as will
new features deemed to be generally useful.
