Hi Philippe and welcome to the forum.

To get a bit more than surface pressure one needs to select altitude data for 850mb and 500mb.
This adds wind and temp for 850mb and geopotential height for 500mb as shown in the info dialog below.

There is not too much info provided by ECMWF for free but the available data can help in evaluating the medium range forecast

As a long retired professional meteorologist, a sailor and a cynic, I do have to question the real value of the ECMWF forecasts over and above GFS and ICON. I am well aware that ECMWF out-performs the rest, slightly better than the U.K. and a little more so than GFS and ICON. But, when I look at www.weathercast.co.uk/services/ensemble-forecast.html , I see very little consistent differences. Such differences as there are, are well within the natural uncertainty, noise if you like, in the weather. There are limits to predictability and that basic fact is not appreciated by the vast majority of the public, even the more meteorologically aware.

As a sailor, I see no point in using Predictwind to get ECMWF output. You are doing a great job, David.

Hello. My name is Ihor, I`m from Ukraine. I work for kNESS Energy in the electricity market monitoring department. Now I am working on a new project connected with the forecasting of the generation of photovoltaic stations. Where I can get parameters such as: solar radiation, temperature, humidity and wind speed. But with discretion 1 hour or less. Thanks. =)
