title28-04-2014 Correction of NCEP energy flux data

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

title17-08-2011 CMC - model upgrade

The CMC global ensemble prediction system was upgraded to version 2.0.2 on 17 August 2011.
The main changes included in this upgrade are:
• The number of members in the ensemble Kalman filter is doubled from 96 to 192.
• The resolution of the medium-range forecasts is changed from 100 to 66 km.
• The model top is raised from 10 hPa to 2 hPa.
• A new dynamical model, with a Charney-Phillips vertical grid, is used.

Further documentation of the operational upgrade can be found at:
