Hello, When I try to download the CERRA sub-daily regional reanalysis data for Europe at height levels from 1984 fom Copernicus [https://cds.climate.copernicus.eu/datasets/reanalysis-cerra-height-levels?tab=download](https://cds.climate.copernicus.eu/datasets/reanalysis-cerra-height-levels?tab=download) to the present using the API and your script, my requests are Accepted but do not progress to ‘Running’. They simply remain at ‘Accepted’. However, if I make the request by manually selecting the fields on your website, it works. Here is the API request I use:

import cdsapi

client = cdsapi.Client(debug=True, quiet=False, timeout=600)

dataset = “reanalysis-cerra-height-levels”  
request = {  
“variable”: [“turbulent\_kinetic\_energy”],  
“height\_level”: [“500\_m”],  
“data\_type”: [“reanalysis”],  
“product\_type”: [“forecast”],  
“year”: [“2017”],  
“month”: [“01”],  
“day”: [“01”],  
“time”: [“00:00”],  
“leadtime\_hour”: [“1”],  
“data\_format”: “netcdf”  
}

result = client.retrieve(dataset, request)  
result.download(“[test.nc](http://test.nc/)”)

What should I do?

Thanks , Regards
