ERA5-Land hourly data from 1950 to present are formed by 30 days in each month, which contradicts the calendar. (data from 2011 to 2015) for the territory of the selected region of Ukraine.

Hi Tatiana,

can you give more details please? (e.g. screenshots)

Thanks,

Kevin

For the north-south (51.8 and 50.2 degrees) and west-east (26 - 31.04 degrees) areas for dates from April to October 2011, the choice of parameters: temperature at 2 m, total precipitation and total evaporation amounts is formed only from the 1st to the 30th for all months, which does not correspond to the calendar with 31 days (May, July, August, October). I checked the dates from 2011 to 2015, the same error.

Hi Tatiana,

as a test i did a request for 31 May 2011 data for the region you specified. This returned 72 grib records (3 variables for 24 hours):

I also plotted the data for 31 May 2011 in Panoply, and they look ok.

Hi Kevin!

Thanks. I found a mistake in the request. I made a choice for any month â€śselect all daysâ€ť and in some month I made a mistake 30 or 31 days. I also look through the data in Panoply. It is very convenient! I am processing the data by MatLab and I found a mistake there. Thanks for your help!

No problem at all, Tatiana, glad to help!
