I downloaded a weather file for Belgium - Brussels area from energyplus website to look for the data of snow depth.

However, the information i have there are all 0 throughout the year. Also, the column on the right side of the snow depth (days from the last snow) is showing 88 for all hour in a year.

The data does not seem correct. Can you help me understand it?

Thanks in advance.

So. Using the file at this link, I do see fluctuation in the value for snow depth (scroll down to January 2nd). The values seem to vary from 0-4. Unsure if these numbers are actually meaningful.

The days from last snow field seems to be garbage as I have 88 all the way through my New York City weather file as well. description

Thanks for the answer. However i mistook my question. Actually the file you sent me is the one i downloaded before. It does not show 0 snow depth but shows snow depth for every month even in summer time

I added an image to my original answer. The following link explains that 88 is a placeholder value, so it seems like most (or no) EPW's are currently populated with meaningful "days since last snow" values.

The actual value for cm of snow depth is a mystery to me, I also observed that the values were highest in summer which, even without knowing anything about Belgium's climate, seemed suspicious :P
