CDS API request for CARRA data failed

Software and Tools API
1

Hello,

I’ve been requesting CARRA data with this type of scripts for several months:

dataset = “reanalysis-carra-model-levels”
request = {
  (…)
  ‘date’: ‘2025-07-16/2025-07-17’,
  (…)
}

But it’s not working anymore and I’m forced to use:

dataset = “reanalysis-carra-model-levels”
request = {
(…)
“year”: [“2025”],
“month”: [“07”],
“day”: [“16”,“17”],
(…)
}

Is this a recent API change? How can I retrieve a time period spanning different months in a single request? (e.g. ‘date’: ‘2025-07-30/2025-08-04’,)

Thanks for your help

Hi,
we advise users to use the webform to build the API requests and check the syntax. If different keywords are used we cannot guarantee the result.
