Invalid ZIP file | ERA5 hourly data on pressure levels

[mammadha]

Hi, Thank you for developing such a useful toolbox.

I am trying to use it for downloading "ERA5 hourly data on pressure levels" (here).

It seems that the file is downloaded:

2022-03-11 20:51:06,377 INFO Welcome to the CDS 2022-03-11 20:51:06,379 INFO Sending request to https://cds.climate.copernicus.eu/api/v2/resources/reanalysis-era5-pressure-levels 2022-03-11 20:51:06,499 INFO Request is completed 2022-03-11 20:51:06,501 INFO Downloading https://download-0015.copernicus-climate.eu/cache-compute-0015/cache/data5/adaptor.mars.internal-1647049186.17651-22468-7-e45254a6-156d-4f7b-9c03-7f29418ad10e.grib to C:\Users\moham\AppData\Local\Temp\tp33b706a1_fd39_4a79_9c08_fe94dd461ad0.zip (7K) 2022-03-11 20:51:06,863 INFO Download rate 19.5K/s

But then immediately, I get the following error:

Error using climateDataStoreDownload (line 62) Invalid ZIP file "C:\Users\moham\AppData\Local\Temp\tp33b706a1_fd39_4a79_9c08_fe94dd461ad0.zip".

I took a look at the source code, and it seems that options.format is forced to zip file, which is not available for this specific CDS dataset. I think it is where the problem arises, but I could not solve it.

I appreciate any help.

Sincerely, Mohammad

Hi Mohammad,

Thanks for letting me know about this. I was able to reproduce with the following code:

datasetName ="reanalysis-era5-pressure-levels";
options.product_type = "reanalysis";
options.format = "grib";
options.year = "2020";
options.month = "01";
options.day = "01";
options.pressure_level = "1";
options.variable = "divergence";
options.time = "06:00";
[downloadedFilePaths,citation] = climateDataStoreDownload(datasetName,options);

I'll try to look at this today.

OK, I've finally solved this problem. I did a major rewrite, and I should release a new version tomorrow. Note that many of these requests can take a long time to process. You can check on the status of your request by visiting the CDS request status page.

release 2.0 is done. Let me know how it works for you!
