Hi, I am using obs = retrieve_evaluation_data.retrieve_weekly_obs('20250519', variable, password) to download weekly observation data. The password is the given password in the registered email. however, I encountered ftplib.error_perm: 530 Login authentication failed error.
Are there any additional access permissions or approvals required to use the ai_weather_quest FTP account?
Hi Mengxuan,
I have just run the following code and I was able to download all observations for the week commencing 19th May 2025.
from AI_WQ_package import retrieve_evaluation_data
tas = retrieve_evaluation_data.retrieve_weekly_obs('20250519','tas',password)
mslp = retrieve_evaluation_data.retrieve_weekly_obs('20250519','mslp',password)
pr = retrieve_evaluation_data.retrieve_weekly_obs('20250519','pr',password)
Output:
File '/observations/20250519/tas_obs_WEEKLYMEAN_20250519.nc' has been downloaded to successfully.
File '/observations/20250519/mslp_obs_WEEKLYMEAN_20250519.nc' has been downloaded to successfully.
File '/observations/20250519/pr_obs_WEEKLYSUM_20250519.nc' has been downloaded to successfully.
Can you please check you have inputted the correct password (case-sensitive). Please get back to me if you still have issues.
Kind regards,
Josh
Thanks for your reply! I tried using the registered email and the default password provided in the welcome email to download the data, but I consistently encounter the error: ftplib.error_perm: 530 Login authentication failed.
I suspect the issue may not be with the password, as I’m able to log in successfully using the same email and password elsewhere. Are there any potential network-related configurations or restrictions I should check?
Thanks again for your help!
Can I just check, do you get an error if you use exactly the same code as me with the only difference being that password, is the password provided in your registration email.
Josh
Thanks a lot! I mistakenly used the login password instead of the forecast submission password. The issue is now solved 
Brilliant. Sorry not the clearest in the welcome email.
