A problem about 'geopotential' when download Complete ERA5 global atmospheric reanalysis dataset

Datasets and Usage C3S - Datasets and Usage

Dear all,

I used the following request to download ‘geopotential’ data in Complete ERA5 global atmospheric reanalysis, specifying all levels from 1 to 137, but the downloaded data only contains the level 1.

request = {
        "date": date.strftime("%Y-%m-%d"),
        "time": date.strftime("%H:%M"),
        "format": "netcdf",
        "levelist": [
            str(l) for l in full_137_levels
        ],  # full_137_levels
        "levtype": "ml", 
        "param": "129",
        "stream": "oper",  
        "type": "an", 
        "area": [36, 120, 36, 120], 
        "grid": [1.0, 1.0], 
    }

And when I specified the data for the level 2 to download, an error occurred:

MARS returned no data, please check your selection.Request submitted to the MARS server:
[{‘area’: [36, 120, 36, 120], ‘date’: ‘2021-01-06’, ‘grid’: [1.0, 1.0], ‘levelist’: ‘2’, ‘levtype’: ‘ml’, ‘param’: [‘129’], ‘stream’: ‘oper’, ‘time’: ‘12:00’, ‘type’: ‘an’, ‘class’: [‘ea’], ‘expect’: [‘any’], ‘expver’: [‘1’], ‘number’: [‘all’], ‘database’: ‘fdbmarser’}]

The job failed with: MarsNoDataError

There is the request ID of the failed request above

Request ID: 9ad554e7-117f-495a-b137-2a06997928a3
Trace ID of the error: 38acae8c-df44-4dfd-9881-680c801af48c

Why is this? Is there something I overlooked? Looking forward to any reply!

Kind regards,

Toby Flenderson

Is anyone here? :smiling_face_with_tear: this problem is still unsolved.

Hi,
please see the note in table 12 for ERA5 complete parameters: ERA5: data documentation - Copernicus Knowledge Base - ECMWF Confluence Wiki
