The planned timetable for the implementation of the IFS Cycle 45r1 is as follows:
| Date | Event |
|---|---|
21.03.2018 | Initial Publication |
| April 2018 | Initial announcement, with test data in MARS |
| May 2018 | Availability of test data in dissemination |
| 5 June 2018 | Expected date of implementation |
The timetable represents current expectations and may change in light of actual progress made.
...
The GRIB model identifiers (generating process identification number) for cycle 45r1 will be changed as follows:
| GRIB 1 Section 1 Octets | GRIB 2 Section 4 Octets | grib_api key | Component | Model ID | |
|---|---|---|---|---|---|
| Old | New | ||||
| 6 | 14 | generatingProcessIdentifier | Atmospheric model | 148 | 149 |
| Ocean wave model | 113 | 114 | |||
| HRES stand-alone ocean wave model | 213 | 214 | |||
New model output parameters
Extended output have been added in cycle 45r1, including precipitation rates, CAPE indices and a total lightning flash density.

Member State users of the "Simple time-critical jobs" framework can test that their scripts will work with the IFS Cycle 45r1 test data by using the limited ECaccess 'events' set up for this purpose:
| Event ID | Event name | Description |
|---|---|---|
| 1633 | e_ms090 | At this stage, the e-suite step 090 (HRES-BC) has been generated. |
| 1634 | e_ms144 | At this stage, the e-suite step 144 (ENS-BC) has been generated. |
| 1635 | e_ms240 | At this stage, the e-suite step 240 (HRES) has been generated. |
| 1636 | e_ms360 | At this stage, the e-suite step 360 (ENS) has been generated. |
| 1637 | e_mslaw | At this stage, the e-suite step law (HRES-SAW) has been generated. |
| 1638 | e_ms1104 | At this stage, the e-suite step 1104 (ENS-MOFC) has been generated. |
| 1639 | msrefc | At this stage, the e-suite step refc (REFORECAST) has been updated. |
For these events, MSJ_EXPVER environment variable is set to 0072 and can be used to specify the IFS Cycle 45r1 test data in any MARS retrievals.
