Using real-world weather - what to do for Horiz Infrared Rad (Comfort Workflow)

Hi Guys,

I am trying to run the LB thermal comfort workflow with real-world weather that I am downloading from open-meteo api ( 🏛️ Historical Weather API | Open-Meteo.com ) to run the workflow with real world weather rather than the EPW weather.

For the workflow I need the following inputs from an EPW that I am substituting with the real-data, and I have done this with no issue:

air temp, RH, wind speed, wind direction

My problem is when it comes to radiation, these are the rad variables I can get from openmeteo:

Diffuse and Direct are straightforward, but this does not include Horizontal Infrared Radiation. If you plot the two you can see there is nothing that appears to be this:

From the EPW:

My work-around has been to just find a day in the EPW around the same time frame, and approx same weather, and use the radiation from the EPW and then the open-meteo data for the other variables. However I would like to stop doing that if possible.

Does anybody have a solution or a source to get this horiz_infrared data?

thanks!

hey, try using DF Horizontal Infrared component that uses Cloud cover and DB and WB temperatures as inputs to calculate the Horizontal Infrared radiation.

I feel so dumb for not finding this! thank you Dmitry.
