This page gives some examples of simulated imagery generated using the RTTOV fast radiative transfer code.
| Met Office UKV NWP system |
The Met Office UKV is a regional NWP system with fixed 1.5km resolution over the UK, stretching to 4km resolution over surrounding areas. The Unified Model is used, with 744(622 @ 1.5 km) × 928(810 @ 1.5 km) grid points. There are 70 levels extending to ∼40km altitude, and the model runs with a 50s (or 30s) timestep. There are currently 4 runs/day, generally to T+36. Lateral boundary conditions come from the 12 km NAE model every half hour, with the initial state currently updated using 3DVAR and latent-heat nudging. Further details of the UKV model can be found here.
| Simulated imagery from RTTOV |
Shown below are simulated 8.7μm images generated from UKV model analysis fields using RTTOV v7 (upper panel) alongside real images from the SEVIRI instrument obtained within a few minutes of the analysis time (lower panel). The images are 3-hourly and date from the 16th and 17th of February 2010. Further information on the generation of simulated SEVIRI imagery can be found here.
