Each Output variable record corresponds to a physical parameter specification.
| Attribute | Value |
|---|---|
| cell_measures | area: areacella |
| cell_methods | amnsia-twm (Weighted Time Mean on Sea-Ice (Atmospheric Grid)) |
| cmip6_frequency | mon |
| cmip6_tables_identifier | SImon (Monthly sea-ice data) |
| cmip7_frequency | mon |
| description | Downwelling longwave flux from the atmosphere to the sea-ice surface (energy flow per sea ice area). Always positive or zero. |
| dimensions | longitude, latitude, time |
| modelling_realm | Sea Ice |
| name | SImon.sifllwdtop |
| physical_parameter | sifllwdtop (Downwelling Longwave Flux over Sea Ice) |
| positive_direction | down |
| processing_note | Note that SIMIP requests the area-weighted average for all intensive variables (i.e., variables that are not proportional to area fraction such as albedo, temperature, or heat flux). Hence, all time samples with non-zero sea-ice fraction are first multiplied by area fraction, then summed, and then divided by the sum of the area fractions. See Appendix C of Notz et al. (2016) for more detail. |
