hi,

I try to download with a python script a bunch of variables from the beggining of the year. No issue except with august month, where i can’t have radiative variables.

My variables are :  
2m temperature, Surface solar radiation downwards, Surface pressure, 10m u-component of wind, 10m v-component of wind, Total cloud cover, 2m dewpoint temperature, specific\_humidity, Surface thermal radiation downwards.

The two radiatives variables are missing. Can’t figure out why.  
Is it something related to ERA5T transition ?

In my python file a put :  
if ‘expver’ in ds.dims:  
ds = ds.mean(‘expver’)

But it doesn’t change anything, even in the raw dataset just downloaded from ERA5 (so before my python routine) i don’t have ssrd and strd variables.

Thanks all if you have any tips !
