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_pm1_ambient_aerosol_particles |
| description | od550 due to particles with wet diameter less than 1 um (ambient here means wetted). When models do not include explicit size information, it can be assumed that all anthropogenic aerosols and natural secondary aerosols have diameter less than 1 um. |
