Hi

We have a production system that downloading the ERA-5 hourly data at daily basis.
For some reason, the following request did not return 24 hours of data and only contains 2-3 hour data.
Any thoughts? Thanks

import cdsapi

dataset = “reanalysis-era5-land”
request = {
“variable”: [“snow_depth_water_equivalent”],
“year”: “2025”,
“month”: “02”,
“day”: [“14”],
“time”: [
“00:00”, “01:00”, “02:00”,

}

client = cdsapi.Client()
client.retrieve(dataset, request).download()

I suppose it is linked to the general issue with timestamp data. Try to load 12-15 Feb instead of 14 only. Perhaps this would help. But I do not know what is the real time. My experiments show that they have 23 hour shift in timestamp, but maybe it is a wrong suggestion.
