unsure of purpose of Tsfc,emisAtmValue,lIn,lOut #1

Open ericwmartin opened 7 years ago

ericwmartin commented 7 years ago

I am adapting your fTg4 function to another program, and I'm wondering what the purpose of the following inputs are: Tsfc,emisAtmValue,lIn,lOut

The Excel VBA code that I'm also referring to has this same function (globe temperature calculation) but it does not have these last four input variables.

Tsfc is surface temperature? Can this be assumed to equal Ta?

What do the variables lIn and lOut represent?

Any help with these 4 variables is greatly appreciated. Thanks!

This code and equations are documented in my thesis (see section 4.2.4 for the Tmrt/UTCI stuff) https://www.researchgate.net/publication/307522405_Development_validation_and_demonstration_of_the_VTUF-3D_v10_urban_micro-climate_model_to_support_assessments_of_urban_vegetation_influences_on_human_thermal_comfort?ev=prf_pub

Tsfc and Ta are likely going to be different, so that assumption might not give accurate results. I probably adapted much of this from the same VBA code. I also have a Python and R version of this UTCI class, if you want to contact me privately.
