I’m trying to update my scripts (running on a linux jupyterhub server) to the new API, and I’m running into some issues.
Firstly, when I follow the instructions to set the contents of my .cdsapirc file (Climate Data Store) I get:
AssertionError: The cdsapi key provided is not the correct format, please ensure it conforms to:
<UID>:<APIKEY>
If I change my .cdsapirc file to include my user ID as instructed, then the error disappears. However, I’m unable to download anything, and always get a 404 client error. I’ve attached an example below. Any thoughts as to what is going wrong?
dataset = "reanalysis-era5-pressure-levels"
request = {
"product_type": ["reanalysis"],
"variable": ["temperature"],
"year": ["2018"],
"month": ["10"],
"day": ["11"],
"time": [
"08:00"
],
"pressure_level": ["1000"],
"data_format": "grib",
"download_format": "unarchived"
}
client = cdsapi.Client()
client.retrieve(dataset, request).download()
