2. Configuration | |
|---|---|
Earth system components included in the analysis system (e.g., ocean, sea-ice, land, etc.) | Atmosphere, land. |
Horizontal resolution of the model, with indication of grid spacing in km (for the different Earth system component included in the model) | TL479 (~40km) for the atmospheric and land models. |
Number of levels in the different Earth system components (for the different Earth system component included in the model) | 100 levels for the atmospheric model. 7 levels for the land model. |
| Frequency of the outputs | Every 6 hours (hourly or daily for some types), monthly statistics. |
| Analysis fields (such as MSLP and 2m temperature) | 00, 06, 12, and 18 UTC Daily means for analysis fields are computed from instantaneous values at 00, 06, 12, and 18 UTC. |
| Two-dimensional average diagnostic fields (such as total precipitation) | Two-dimensional average diagnostic fields are produced 1-hourly for 0-23h. Average accumulations within a particular day=date for two-dimensional average diagnostic fields are the average from the following forecasts:
|
| Top of the atmospheric model | 0.01 hPa. |
| Number of analysis cycle per day | 4 |
| Earliest start date | September 1, 1947 |
| Integration time step | 720 seconds for outer model with TL479 resolution, 600 seconds for inner model with TL319 resolution. |
| Length and frequency of the longest forecast | Not applicable |
| Dataset latency | 3 days |
