[QGIS-Developer] Problems opening .grib data in QGIS 3.4

[Tim Sutton]

Hi All./ Martin


I’m trying to get some mesh data for a presentation to a bunch of climate geeks later today. I tried grabbing a sample dataset from ECMWF/Copernicus like this:

#!/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": "0/1/2/3/4/5/6/7/8/9/10/11/12/13/14/15/16/17/18",
    "stream": "ewda",
    "time": "06:00:00/18:00:00",
    "type": "fc",
    "target": "output",
}, "global-waves-2018-08-01-0600-1800.grib")                                                                          
~                                                                                                                     


When trying to add it as a mesh in Data Source Manager it gives a ‘file not supported’ error. So two questions:

1) anything obvious I am doing wrong?
2) where is the best place to get some demo .grib or NetCDF data that I can use to show off the cool new mesh stuff in 3.4 (with vector arrows etc).

Regards

Tim
