Hello. I tried to get the reanalysis-era5-single-levels dataset via the API, but I got a message that the url cannot be found. The url and key in .cdsapirc seem correct… I could use some your help. I would like to know reasons strongly. ---

After updating the .cdsapirc the API gave about five http 500 errors, but then actually started to download. But as I was looking at the webpage at the same time, I think while API was getting 500’s, the job itself was actually triggered and in progress, as seen in “your requests” section. So something is still off, but at least the data can be accessed programmatically now. ---

Hi everyone, I’m trying to retrieve ERA5 reanalysis data using the `cdsapi` Python library. Here is my example code: > import cdsapi > > client = cdsapi.Client() > > dataset = ‘reanalysis-era5-pressure-levels’ > request = { > ‘product\_type’: [‘reanalysis’], > ‘variable’: [‘geopotential’], > ‘year’: [‘2024’], > ‘month’: [‘03’], > ‘day’: [‘01’], > ‘time’: [‘13:00’], > ‘pressure\_level’: [‘1000’], > ‘data\_format’: ‘grib’, > } > target = ‘download.grib’ > > client.retrieve(dataset, request, target) I have properly configured my `cdsapirc` file, but I keep getting the following error: > `Recovering from connection error [HTTPSConnectionPool(host='ads.climate.copernicus.eu', port=443): Max retries exceeded with url: /api/catalogue/v1/messages (Caused by NameResolutionError(": Failed to resolve 'ads.climate.copernicus.eu' ([Errno -2] Name or service not known)"))], attempts 1 of 500...` Any suggestions on how to fix this? Thanks in advance! ---

The URL in your cdsapirc is wrong. It should be cds.climate.copernicus.eu. ---

> [@Luke\_Jones](#): > > cds.climate.copernicus.eu Great! Now it works. But if I want to download the dataset **“CAMS-Europe-Air-Quality-Reanalyses,”** which server should I use?.. I am following the tutorial from [CAMS European air quality index](https://github.com/stewartchrisecmwf/training/blob/main/CAMS_European-air-quality-index.ipynb) to download the dataset **“CAMS-Europe-Air-Quality-Reanalyses”** , but I encountered the following error: ```auto HTTPError: 404 Client Error: Not Found for url: https://ads.atmosphere.copernicus.eu/api/v2/retrieve/v1/processes/cams-europe-air-quality-forecasts ``` Could you please confirm which server I should use to correctly access this dataset? Thank you in advance for your help! ---

To access ADS datasets you need to use the ADS URL: [https://ads.atmosphere.copernicus.eu](https://ads.atmosphere.copernicus.eu). Note that it’s not just the “ads” part that’s different. If you want to be able to easily switch between ADS and CDS you can give the URL directly to the cdsapi.Client in Python, e.g. client = cdsapi.Client(url=“[https://ads.atmosphere.copernicus.eu/api](https://ads.atmosphere.copernicus.eu/api)”, key=“XXXXXXX”) Changing the URL here is easier than changing your ~/.cdsapirc. ---

Just wanted to check my issue isn’t relevant to this above issue. On the online system I’m able to download some of the Fire Indices - when I copy and paste the api code and run this locally: import cdsapi dataset = “cems-fire-historical-v1” request = { “product\_type”: “reanalysis”, “variable”: [“fire\_weather\_index”], “dataset\_type”: “consolidated\_dataset”, “system\_version”: [“4\_1”], “year”: [“2024”], “month”: [ “01”, “02”, “03”, “04”, “05”, “06”, “07”, “08”, “09”, “10”, “11” ], “day”: [ “01”, “02”, “03”, “04”, “05”, “06”, “07”, “08”, “09”, “10”, “11”, “12”, “13”, “14”, “15”, “16”, “17”, “18”, “19”, “20”, “21”, “22”, “23”, “24”, “25”, “26”, “27”, “28”, “29”, “30”, “31” ], “grid”: “original\_grid”, “data\_format”: “grib” } client = cdsapi.Client() client.retrieve(dataset, request).download() … I get the following error: * * * —\> 34 client.retrieve(dataset, request).download() HTTPError: 404 Client Error: Not Found for url: [https://cds.climate.copernicus.eu/api/retrieve/v1/processes/cems-fire-historical-v1/execution](https://cds.climate.copernicus.eu/api/retrieve/v1/processes/cems-fire-historical-v1/execution) process not found dataset cems-fire-historical-v1 not found * * * I’ve checked my cdsapirc file and it’s pointing to url: [https://cds.climate.copernicus.eu/api](https://cds.climate.copernicus.eu/api) So I don’t think that’s the issue.
