Each Physical Parameter record defines a MIP variable name, associated with a CF Standard Name. Formerly known as MIP Variables in CMIP6
| Attribute | Value |
|---|---|
| cf_standard_name | atmosphere_optical_thickness_due_to_ambient_aerosol_particles_assuming_clear_sky |
| description | AOD from the ambient aerosols in clear skies if od550aer is for all-sky (i.e., includes aerosol water). Does not include AOD from stratospheric aerosols if these are prescribed but includes other possible background aerosol types. Needs a comment attribute "wavelength: 550nm" |
| flag_change_since_cmip6 | True |
| name | od550csaer |
| processing_comment | NOTE - change in CF standard name since CMIP6. New standard name was proposed late, so may not be accepted in time for the v1.2.2 release. Data providers to check. |
