radiation

What version of the code are you using? Relevant for all CAM versions, to the best of my knowledge (checked the CAM6 code based on the Github repository). Describe your problem or question: This question is related to cloud sampling in the radiation transfer module as part of the...

Hello！ I was recently studying the surface energy balance, and while using CESM1 Last Millennium Ensemble data, I had questions about the direction of LWCF, SWCF. I know that FLUS = FLNS + FLDS, but the Pearson's correlation coefficient between FLUS calculated by this formula and TS is 1. I...

Hello everyone I added a new aerosol with dust components in CESM, but I don’t want this new aerosol to have radiation effects. I just want it to be transported and settled along with the dust aerosol. I tried setting the parameters in the '&rad_cnst_nl' corresponding radiation file to 0 or a...

When running simulations with volcanic forcing in a fixed sea-surface temperature condition to get an estimate of the forcing, what output variables are the appropriate ones to use? From what I understand, the standard way to do this is to calculate it as the sum of the shortwave + longwave...

I am confused why the clearsky upwelling longwave flux at the surface (FLNSC - FLDSC) is not equal to the total sky upwelling longwave flux the the surface (FLNS - FLDS). There are regions where the total sky upwelling flux is over 100 W/m2 and/or 1.5+ times more than the clear sky. I looked...

Dear CESM community, My colleague and I are trying to perform some simulations using CESM1.2.2 that modify SW and LW at different layers. For example, we want to modify the model to reflect more SW upward or reduce the outgoing longwave at the atmospheric layer near the tropopause. I checked...

Hi, I am looking at the radiation calculation in CAM, and notice this in the CAM3 documentation: I wonder if this is still true in CAM5 or CAM6, and if there is any more detailed documentation on how the properties of this layer are chosen? Thanks!

Hello, I was looking at this site that shows a variety of things, including the equilibrium surface temperature given a series of specified parameters. It gives an option to swap between the CCSM3 and the Chou Model, of which I think more can be found about here. The models output different...

 In CAM 3, it was possible to add a scaling factor for aerosol mass using SCL_RF options. I was wondering if there is any way to do this in CAM 6. I was also wondering if it is possible to scale aerosol optical depth instead of the mass. Ideally, I would want to do this with radiation...
