Hi everyone,
I am having issues with the precipitation data from ERA5-Land.
I downloaded the hourly data and calculated the monthly accumulations by summing all the 00:00 hourly values for each month.
I compared these results with the ERA5-Land Monthly Average Reanalysis data, and I noticed significant differences for some grid cells (up to 40 mm/month), while for others, the values are quite identical.
Could anyone explain what might be causing this discrepancy ?Is it because I am converting the monthly average to total precipitation by multiplying it by the number of days in the month?
The period analyzed is from 2022 to 2024, and the area is 35.5–36.3°N and 74.5–74.9°E.
Hi,
please have a look here: Issue affecting ERA5-Land monthly averaged reanalysis for the period September 2022 to February 2024
Thanks
