Inverse of air density (alt) from wrf-chem output

Post by sm2020 » Mon Jun 29, 2020 10:32 am

Hi All,
Is there any way to obtain variable alt (inverse of density of air) from output of WRF-Chem v3.9 model using NCAR Command Language (NCL)?
Note: variable 'alt' is used in chemistry modules of WRF-Chem to convert mixing ratio (in kg/kg-air) to concentration (ug/m3).
