2. Configuration | |
|---|---|
Earth system components included in the analysis system (e.g., ocean, sea-ice, land, etc.) | |
Horizontal resolution of the model, with indication of grid spacing in km (for the different Earth system component included in the model) | TL639, 31 km atmosphere 0.36o ocean waves |
Number of levels in the different Earth system components (for the different Earth system component included in the model) | 137 levels in the atmosphere |
| Frequency of the outputs | 1-hourly |
| Analysis fields (such as MSLP and 2m temperature) | 00, 01 ... 23 UTC Daily means for analysis fields are computed from instantaneous values at 00, 01 ... 23 UTC. |
| Two-dimensional average diagnostic fields (such as total precipitation) | Average accumulations within a particular day=date are the average from the following forecasts:
|
| Top of the atmospheric model | 1 Pa |
| Number of analysis cycle per day | 2 |
| Earliest start date | 1 January 1940 |
| Integration time step | The model time step is 12 minutes for the HRES and 20 minutes for the EDA, though occasionally these numbers are adjusted to cope with instabilities |
| Length and frequency of the longest forecast | 18 hour forecasts initialised twice daily from analyses at 06 and 18 UTC |
| Dataset latency | ERA5T 5 days behind real time (preliminary product) ERA5 2–3 months (final product) |
