The table below shows the percentage of Metop-B (GRAS) observations from May 2015 that would meet the early and late cutoffs at several NWP centres, given receipt times at the Met Office (data from GTS via DMI). The cutoff information for each centre was obtained from this page. Note that if a range of cutoff values were given, the pessimistic limit has been selected for this table. Also, it is assumed that the assimilation windows are centred at 00Z etc, but this is not always true (e.g. for ECMWF), but this probably will not affect the results greatly for assimilation windows larger than 6 hours.
19216 Metop-B (GRAS) observations were received by the Met Office for this period.
| Centre | Early run | Late run |
| Met Office | 80.32% | 100.00% |
| NCEP | 63.21% | 100.00% |
| NRL | 92.89% | 100.00% |
| JMA | 75.04% | 100.00% |
| ECMWF | 99.83% | 100.00% |
| Environment Canada | 77.87% | 100.00% |
| Meteo-France | 66.81% | 100.00% |
| DWD | 95.24% | 100.00% |
| CMA | 94.36% | 100.00% |
For comparison, this is the equivalent table for COSMIC-1 (data from UCAR via the GTS for same period). 12875 observations were received by the Met Office.
