Hi Tim,
I tried your dataset and got the same error in QGIS. Then when I tried to
download the netcdf version (which sometimes works better with mesh in
QGIS):
#!/usr/local/bin/python
import cdsapi
c = cdsapi.Client()
c.retrieve(
"reanalysis-era5-complete",
{
"class": "ea",
"dataset": "era5",
"date": "2018-08-01",
"domain": "g",
"expver": "1",
"number": "0/1/2/3/4/5/6/7/8/9",
"param": "238.140",
"step": "0",
"stream": "ewda",
"time": "06:00:00/18:00:00",
"type": "fc",
"format": "netcdf",
"target": "output.nc",
}, "global-waves-2018-08-01-0600-1800.nc")
I got he following error:
First GRIB is not on a regular lat/lon grid or on a regular Gaussian grid.
Exiting
For your example, you can use probably one of these datasets (I have tried
aerosols and they seem to open fine in QGIS):
https://atmosphere.copernicus.eu/catalogue#/
Let me know if you have any problems.
Cheers
Saber
