Raw ECMWF operational data (OD) are available every day with every forecast, but an archive of pre-processed-for-TM5 fields is not officially maintained.
However, data subsets have been processed and made available by some groups. This page describes them.
Pre-rocessing by TM5
At the global 1x1 resolution with 60 or 91 native layers, depending on the IFS atmospheric model version at the time of production. Data is also available coarsened to global 6x4 and to selected zoom regions.

The older processing of meteo data by TMPP is now deprecated. It processed:
- fields with T159/N80 ECMWF resolutions, and
- time resoultion : 6 hourly for model level fields, 3 hourly for surface fields
For 1999 nov - 2006 jan
From ECMWF IFS model running on 60 layers, were produced:
base set global 3x2 on ml60 levels stored in: ec:/nlh/TM/meteo/od/fc/ coarse global 6x4, and zoom regions on 3x2 and 1x1 on ml25 levels: stored in: ec:/jrd/TM/meteo/od/fc/
2005 oct - 2011 may
From ECMWF IFS model running on 91 layers, were produced:
global 3x2 on ml91 was updated daily by Michiel van Weele (nlh) stored in: ec:/nlh/TM/meteo/od/fc/ (not to meteo-ml91!)
coarse 6x4 and zoom 3x2 and 1x1 on tropo34 levels: adhoc production by Andy Jacobson (ru9) or Arjo Segers (nl5) stored in: ec:/nlh/TM/meteo-ml91/od/fc/ regions: afr asi aus eur nam sam note that region 'anz' (Australia/New-Zealand) replaces 'aus' from 2009 onwards.
Fields pre-processed on c1a at ECMWF, with openMP, and with a version of TM5 older than revision #4378 (2012-04-20), have been corrupted. This is essentially all met fields reported here. The conclusion:
As far as convection fields are concerned, the differences are not large enough to consider reprocessing the meteo.
