Miscellaneous Climate Models
Model |
Offline Contrail Modelling and Analysis tool (COMA) |
Description / Purpose |
Calculate contrail coverage from aircraft movements. |
Data source / Input |
ECMWF/NCEP met. data, aircraft movements, propulsion efficiency, satellite observations of contrail coverage. |
Output |
Natural cirrus clouds, potential contrail coverage and contrail coverage. |
Spatial dimension |
Country, regional, global. |
Temporal dimension |
6-hourly, monthly, seasonal and annual. |
Sample applications |
Contrails coverage trends, impact of fuel efficiency on contrails coverage. |
Model |
Edward-Slingo radiative transfer model |
Description / Purpose |
Implementation of a radiative transfer code from the UK Met Office. Based upon an implementation and testing of the E-S model for cirrus clouds with the Met Office’s global climate model (GCM). |
Data source / Input |
Atmospheric composition, land cover, cloud fields, albedo, meteorology. |
Output |
Radiative transfer over ‘columns’ of the atmosphere. |
Spatial dimension |
Country, regional, global. |
Temporal dimension |
Monthly, annual. |
Sample applications |
Many applications: used at MMU for aircraft applications of contrails, cirrus (main developer) ozone changes from chemical perturbations. |
