Precipitation issues #23

Closed mvhulten closed 2 years ago

mvhulten commented 2 years ago

From the Quick Start I inderstand that one grid cell is 1 mm. This is good and implies an average expected precipitation of 1 mm/h.

On the top are state variables, one may assume. However, the precipitation unit is mm. I think this should be mm/h.

Often I see no precipitation in the graph for the upcoming hour, but at the top I see "1 mm", while I expected "0 mm/h" or "0". Is maybe precipitation always rounded up?

Hi @mvhulten, I'm not the app developer, but I just did a little bit of digging and I think I can explain the confusion. This is the explanation given on the "Quick Start" page that shows up when you open the app:

Each grid cell is a given amount of precipitation, as indicated in the top bar. Normally, each cell will be 1 mm, or 0.05 inches. This means that a bar which is four cells high equates to four millimetres, or 0.2 inches of precipitation. [...] The number to the right of the relative humidity is the precipitation scaling, as described in the previous paragraph.

So it seems like this number isn't meant to represent real-time data, but instead just provide a reminder of what scaling is used to display humidity. Depending on your settings, it will always be fixed at either 1 mm or 0.05 in.

Cheers

Yes it is like 122800 says.

Right, thank you for the clarification! It is right there in the Quick Start, as indicated in the top bar, which I did not read carefully.

Since the square is an actual integrated precipitation, the unit of mm (or inch) is of course also correct.

Some might complain that this item in the top bar, being not real-time data, is inconsistent with the rest. But I would not know where to better put that rather useful information.
