incorrect presentation of the past weather

I'd like to report the inaccurate presentation of the past weather on your maps which happens as far as I can see rather occasionally but is quite annoying and actually undermines your credibility. While the future weather predictions (even for the next few hours) may always be incorrect, there is no excuse, in my opinion, for not showing the PAST weather incorrectly.

I'm based in Wrocław (Poland) and your rain map shows clear, although light rain (up to 0.4mm) yesterday (7.09) between 4-5pm, widespread over quite a large area, far exceeding the city borders. I can reassure there was no rain AT ALL in those hours, at least in the east of Wroclaw, so your data is clearly wrong.

And it has happened at least occasionally in the past. I remember one day last winter with quite heavy and widespread snowfall (with well over 1cm thickness, as snow ploughs were out on the streets working) which went on for quite a few hours, while your snow cover maps claimed ZERO snow cover - and never rectified. Curiously, when the snow had mostly melted a couple of days later, you did show some snow cover but only at that point - not when it actually snowed heavily before!

I'm not checking the past weather frequently (only when I need it for some reason, like to see if it rained overnight and how much) so such mistakes may be more frequent actually.

And what is here additionally annoying - some months ago you started to obstruct the access to the weather projection for over 7 days ahead with the message on the screen asking for financial support. How can anyone be convinced to do that if even the past weather isn't always displayed correctly???

You need to look at the radar and its history. It shows actual measurements. Even then, however, it does not represent precipitation exactly at ground level — the radar measures precipitation at an altitude of around 2 km, and in some cases it may evaporate before reaching the ground.

Ventusky is a visualization platform. And the reality is that nobody in the world knows exactly what the weather was at every location on Earth at any given time in the past. What would such information even be based on? Weather station networks are sparse, radar coverage is not available everywhere and does not measure everything, satellites cannot determine precipitation precisely, and so on. You are asking for something that simply cannot be known with that level of accuracy.
