Re: ERA5 dataset

Hi all,
Has anyone managed to get era52arl working when downloading from "new" (circa 2018) Copernicus system? I had successfully converted ERA5 data to HYSPLIT when I downloaded ERA5 from the old MARS system circa 2017. The error I get is the same "latitudeOfFirstGridPointInDegrees" error that is discussed in this thread. Looking in the grib files, it appears that the variable exists in the files. I've included the python code I used to retrieve one of the files below:
#!/MYPATH/anaconda3/bin/python
import cdsapi
c = cdsapi.Client()
c.retrieve('reanalysis-era5-complete', {
'class': 'ea',
'date':'2013-09-05',
'expver': '1',
'levelist': '10/20/30/50/70/100/125/150/175/200/225/250/300/350/400/450/500/550/600/650/700/750/775/800/825/850/875/900/925/950/975/1000',
'levtype': 'pl',
'param': '60.128/75.128/76.128/129.128/130.128/131/132/133.128/135.128/138.128/155.128/157.128/203.128/246.128/247.128/248.128',
'stream': 'oper',
'time': '00:00:00',
'type': 'an',
'area': [50, -105, 0, -10],
'format':'grib'
}, 'era5_atlantic_201309050000')
In theory, I suppose I could go back to using the MARS system, but it seems like the Copernicus system is the preferred way to retrieve the data, so I'd like to get this working with that data if at all possible.
Thanks in advance,
Chip Helms
