deterministic forecasts
Control and perturbed forecasts are identified in section 1 and 4. The following tables explains how to code them in GRIB2:
| Section 1 | ||||
|---|---|---|---|---|
| ensemble forecast | deterministic forecast | |||
| Octets | Example perturbed (pf) | Example controlcontrol (cf) | forecast * (fc) | |
| 21 | type of processed data | 4 | 3 | 2 |
(*) high-resolution forecast interpolated to ensemble resolution (new request from 2020 for TIGGE, phase III)
| Ensemble (section 4, template 4.61) | |||||
|---|---|---|---|---|---|
| ensemble forecast | deterministic forecast | ||||
| Octets | Example perturbed (pf) | Example controlcontrol (cf) | forecast * (fc) | ||
| 8-9 | product definition template number | 1/11* | 1/11* | 0/8* | |
| 35 | type of ensemble forecast | 255 (missing) | 3 | 1255 (missing) | |
