I downloaded swe, 2mt, sd, tp and soil moisture for a swath of Canada from 1950 to 2022. Even though the documentation for ERA5-Land says that they are all instantaneous variables, except for tp which is accumulating, the “instantaneous” variables of 2mt and sd both do NOT start at 1950-01-01 00 UTC but at 01 UTC instead. Meanwhile, swe starts at 00 UTC, which is what I would have expected for all the instantaneous variables. This results in the there being 8759 timesteps for some of the instantaneous variables and 8760 for others.
Has any one else noticed this? Is there a reason for this, or is this an error?
