The Met Office TIGGE data now includes data from the higher resolution, 7-day MOGREPS-G global ensemble (rather than MOGREPS-15, as used up to 00Z 15th July). The new data are being provided in near-real time from 00Z 6th November, and it is planned to back-fill the gap in due course. The new ensemble data includes 12 members run four times a day, with a reduced number of parameters. See attachment below for more details. |

From Tuesday 15th July, the 15-day MOGREPS-15 EPS data will no longer be sent to TIGGE. It will be replaced by higher resolution MOGREPS-G data, with a 7-day range. There will be a gap in the data provision, but it is planned to back-fill the missing data within a few weeks. The number of TIGGE parameters available from the new MOGREPS-G feed will be significantly reduced. See attached file for more details |

A recent review of the NCEP TIGGE data has shown that there were errors in the five time-integrated energy flux fields: outgoing long wave radiation, surface latent heat flux, surface net thermal radiation, top net solar radiation and surface sensible heat flux. The data have been corrected from 9th April 2014, but unfortunately it is not feasible to correct past data. Thanks to NCDC, who post-process twelve of the NCEP TIGGE parameters, for indentifying and correcting the problem. For furthe ... more |
