UPDATE (15 Oct 2020):

Early in 2020 the test products described below (i.e. charts) became operational, and the charts were then replicated on the ECMWF forecasts web page.
On 7th October 2020 ECMWF opened up all of its forecast web charts for free access, worldwide, with the aforementioned products now being accessible at the following links:
Early warning for cold spells over Europe (Extended Range) / Trajectories (Medium Range)
Stratospheric sudden warning
Weather regimes extended range forecast
The previous links, highlighted below, are now being discontinued. So please update your bookmarks to use instead the links listed above.

From time to time ECMWF develops new forecast products to help users interpret the ECMWF model outputs. As part of the development process, potential products may be made available in test mode. This allows users to provide feedback on the usefulness of the product and helps to ensure that the final product meets the users’ needs.

Please note that test products provided here are for a limited time, and are not operationally supported, although ECMWF makes best efforts to ensure they are routinely available. These products should not be relied on for operational use. Note that in general the test products are available only in graphical form and do not follow the official release time schedule of forecast data.

ECMWF welcomes feedback on these test products – please provide your feedback in the comment panel at the bottom of the relevant product page.

POINT RAINFALL

The point-rainfall is a test product, developed at ECMWF. It is not part of ECMWF's operational suite. It is released on daily basis at 13 UTC but please note that it could be delayed in certain cases. In those cases, a note will appear in the section "NEWS" to let the users know about any delay or problem with the release of this test product. Apologises for the inconveniences that this may cause.

Point Rainfall Description

(work in progress)

This test product consists in a statistical post-processing of ECMWF's ensemble (Control Run + 50 Perturbed Forecasts) in order to define probabilities for point-rainfall.

3 month-verification (June, September and December 2016) has already been computed and has been shown the benefits of this method at global scale.

The project aims to compute the 6 and the 12 hourly accumulations for the post-processed rainfall. At the moment just the 12 hourly accumulations are available. In 2017 the 6 hourly accumulations will be computed as well.

Due to the fact that Europe has the biggest dataset of observations for future verification, in order to better take into account the diurnal and nocturnal cycle, the 12 hourly accumulations between 6-18 UTC and 18-6 UTC are considered (since those times define day and night time in Europe).

After this testing period, we aim to proceed with the computations until day 5 for the following intervals:
