QUICK TUV CALCULATOR
This web page runs the 5.3 version of the TUV model. You can run the model for a specified latitude, longitude and time (input option 1), or for a given solar zenith angle (input option 2). In either case, you must also specify the additional parameters in the second column. Also, you may select to print out the photolysis rates and/or the solar actinic flux spectrum at a given altitude above the surface (output option 1), or the erythemal UV and/or solar irradiance at that altitude (output option 2). For any problem, or to send comments, email TUV administrators.
The wavelength parameters are used to specify the operational range of the TUV Calculator. You can use wavelength start and end to focus on a particular chemical species. Set increments to -156 for an auto-generated wavelength grid. For more detailed information, please read the TUV Instructions.
If your usage of the TUV calculator is high-volume (greater than ~100 requests per day), we suggest that you download the TUV FORTRAN code and build an executable to perform the calculations locally on your own computer.
For video instructions on using the TUV Calculator, you may watch this external video Using the Quick TUV Calculator, created by Pedro J. Aphalo at the University of Helsinki.
