Hello,
I see in the announcement of CAMS version 49r1 the following statement:
“new aerosol optical properties to account for hydrophilic and aspherical dust”.
Could you please provide us with the actual values of the optical properties affected by this change (ie. refractive index, modal radius, mass extinction coefficient, etc…) ?
Thanks a lot !
Dear Jerome,
You can find more information on the optical properties used in cycle 49R1 in the documentation, available at IFS Documentation CY49R1 - Part VIII: Atmospheric Composition | ECMWF, in Chapter 5.
Also, specifics can be found here: Aerosol-radiation interactions in the IFS - ECMWF Radiation Scheme - ECMWF Confluence Wiki (the columns “prognostic CAMS from 49R1”).
Kind regards,
Samuel Remy
