ERA5 data download - 500 Internal Server Error

[Sven Borgstrom]

Hi Yunjun,

first of all thank you for the advice about the missing "geometry*.h5" file: it was a problem related to a wrong path in the (old) template I used in the "mintpy" dir.

Now I run MintPy and the problem arise trying to download the ERA5 data from ECMWF.

I've regularly installed (and working) "pyaps3" and I also set in the template the rows

##--------tropospheric delay correction:
mintpy.troposphericDelay.method = pyaps
mintpy.troposphericDelay.weatherModel = ERA5
mintpy.troposphericDelay.weatherDir      = ~/WEATHER

With the weatherDir regularly set.

In the attached file the output of the terminal: as far as I can understand the download issue is from the ECMWF side (500 Internal Server Error).

Are you able to download ERA5 data? I also opened a ticket on the ECMWF Help Page but still waiting for an aswer.

Cheers,

Sven.

No, unfortunately I'm still unable to download ERA5 data.

I received also the answer for the ticket I've opened on ECMWF; thier answer for short:

...

I can confirm that there were no changes made to the ERA5 archive access since the Back extension data (1950-1978) was released

...

Could I suggest that you try downloading the hourly ERA5 on pressure level data for 13/12/2014 for your selected area using the web interface at https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-pressure-levels?tab=form

...

If this is successful, try the same request using the CDS API. Let me know if this is still not working.

...

With regard to the CDS API use see

https://confluence.ecmwf.int/display/CKB/How+to+download+ERA5

B.t.w. suggestions from the ECMWF Help Desk are impractical in our case, as we usually deal with a lot of images, as we should download and rename each single file.

Yunjun, could you please give us some advice?

Cheers,

Sven.

ERA5 downloading works for me. 

I can not tell where exactly went wrong, would recommend:

1. Try the pyaps3/examples/TestECMWF.ipynb notebook to get it work first, as described on the installation page: https://github.com/insarlab/MintPy/blob/main/docs/installation.md#notes-on-pyaps

2. Try the suggestions from ECMWF Help Desk: they look good to me.
