The effect of EROD's value on EDUST.

Post by Zhanghaopeng » Mon Apr 25, 2022 1:56 pm

Hello,everyone.
I want to know the effect of EROD's value on wrfout'EDUST. I tried simply adding some EROD where the EROD value was zero, but the change in the EDUST in the result was negligible.According to my knowledge, I think modification of EROD will have an impact on EDUST, but the change in the result is not great. Does anyone know why? I hope someone can help me. Thank you.Here are my namelist.input.

Hi

Dust emissions are linearly related to EROD values, however, emissions are nonlinearly related to wind speeds and so if there are very small emissions to begin with, the changes will likely also be small. Please see the code:

/chem/emissions_driver.F
and
/chem/module_gocart_dust.F

to help understand how EROD is used to calculate the emisisons.
