Update of ECMWF forecast system. A new version of ECMWF model (IFS cycle 41r2) was introduced at ECMWF. Click here for full details. The main consequences for ECMWF-TIGGE data are: - Introduction of a new form of the reduced Gaussian grid, the octahedral grid, for HRES, ENS and ENS Extended;
- Horizontal resolution of the HRES increased from TL1279 / N640 to TCO1279 / O1280, where subscript C stands for cubic and O for octahedral;
- Horizontal resolution of the ENS increased from TL639 / N320 to TCO639 / O640 for ENS (Days 0 - 15) and from TL319 / N160 to TCO319 / O320 for ENS Extended (Days 16 - 46);
- For the medium-range ENS there will no longer be a decrease of resolution at day 10: the ENS Days 11 - 15 will be run at the same TCO639 / O640 resolution as ENS Days 0 - 10;
