This list describes the status of some feedback and requests put forward by users during the User Voice Corner feedback session at the ECMWF UEF meeting held in June 2019 (this update on actions was delayed by COVID). Items are included here mainly to provide useful clarification and/or an update where significant progress has already been made. Many more items are being worked on or considered for future action. References are made below to cycle 47r1; this new IFS model version went live on June 30th 2020. ECMWF is also working on feedback provided at UEF 2020, the intention is to provide a web page describing progress on those items early in 2021.

• Rationalise computation of CAPE and other convective indices in various ways

For cycle 48r1 (late 2022?) preparations have been made to introduce several new CAPE-type diagnostics, following a collaboration with ESSL (the European Severe Storms Laboratory). In Cycle 47r1 (June 2020) the method of computation of convective inhibition (CIN) was markedly improved, and it was also made consistent with the CAPE computation level (for more details see here).

• 2m temperature biases, of different types, noted by many users

Following a cross-departmental project at ECMWF - USURF - biases in near surface parameters are now much better understood, and various initiatives are underway to reduce these (see e.g. here). ECMWF is also exploring, in an EU-funded project, how ecPoint post-processing can help with error-source identification and correction. Introduction of urban tiles (for heat island effects) is also part of ECMWF future plans.

• Requests for better visualisation of extended range and long range (=monthly & seasonal) output

Although this will not satisfy all requests, ECWMF has recently introduced a web-product-based CDF-intercomparison tool for weekly mean 2m temperature and weekly total precipitation, to see how handling by successive extended range forecasts compares, for a user-selected (clickable) site. We have also revised the extended range charts, adding more geographical areas and now providing forecasts out to 6 weeks ahead rather than 4.

• Can we have more cluster-style products?

ECMWF has now moved from experimental to operational status a number of regime-related products, for both medium and extended ranges. These effectively cluster output according to standard regimes (such ad NAO+) and display the output in new and innovative ways.

• ecCharts is still slow!

ECMWF released a major new version of ecCharts, focused on this particular problem, and whilst performance is still not perfect it seems that the number of users complaining has diminished as a result.
