This was not possible due to scheduling of other work on our web sites, and I would like to announce that we are now going to make the new charts catalogue the default on 3rd May 2017.
At this time we are not aware of any problems with the new charts catalogue but if you do have any further feedback we are still very happy to receive it via our contact us page.
For details on this change please refer to my previous email (attached below for reference).

A beta version of the new charts catalogue has been released. In this new version we have:
- merged the charts in a single catalogue that can be browsed through facets
- reviewed the medium range charts
- charts are generated from native data resolution
- high resolution charts are made available based on ECMWF dissemination schedule
- their size has been increased and more geographical domains are available
- with a single click you can now access the meteograms at any point (where applicable).
We very much welcome your feedback

ECMWF new model cycle (IFS cycle 43r3) will contain a number of meteorological changes (provisional implementation date 20th June 2017):
Assimilation
- Improved humidity background error variances directly from the EDA like for all other variables.
- Revised wavelet filtering of background error variances and revised quality control of drop-sonde wind observations in 4DVAR to improve tropical cyclone structures.
Observations
- Increased use of microwave humidity sounding data by adding new sensors (SAPHIR, GMI 183 GHz channels).
- Activation of 118 GHz channels over land from MWHS-2 instrument on-board FY-3C.
- Harmonised data usage over land and sea-ice for microwave sounders (adding MHS channel 4 over snow, adding some ATMS channels, lower observation errors for MHS data over land).
- Improved screening of infrared observations for anomalously high atmospheric concentrations of hydrogen cyanide (HCN) from wildfires.
- Improved quality control for radio occultation observations and radiosonde data.
Model
- New, more efficient radiation scheme with reduced noise and more accurate longwave radiation transfer calculation.
- New aerosol climatology based on ‘tuned’ CAMS aerosol re-analysis including dependence on relative humidity.
- Increased super-cooled liquid water at colder temperatures (down to -38C) from the convection scheme.
- Visibility calculation changed to use ‘tuned’ CAMS aerosol climatology.
