PyAPS

Hi Yunjun,

I get this error for pyaps tropospheric correction, do have any idea what could be the reason:

Hi @mirzaees, the error shows that num_date is 0, a.k.a., no grib file found, you may want to check from there.

I've run into something similar (in my case grib files found but couldn't download) and non of the previous issues were relevant or resolved the problem. Looking into the related scripts I found the tropo_pyaps3.py script us try and except at line 591-610. If the Copernicus licence conditions not accepted (I thought I did...) then it fails to download the products although products found. Except trying 3 times there were no useful information. By removing the ERA5 download from the try and except the problem was clearly raised in the error message:
" Exception: Client has not agreed to the required terms and conditions.. To access this resource, you first need to accept the termsof 'Licence to use Copernicus Products' at https://cds.climate.copernicus.eu/cdsapp/#!/terms/licence-to-use-copernicus-products "

Maybe worth to add a warning for this scenario?!

I agree! There are some discussions here also (#226). Contributions are welcomed.
