Download CDS data to run Pangu Weather model

[sudhir2016]

I was trying to run the Pangu Weather model in Google Colab using ai-models --file .

Model help showed me I need this data

Grid: [0.25, 0.25]
Area: [90, 0, -90, 360]
Pressure levels:
Levels: [1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 50]
Params: ['z', 'q', 't', 'u', 'v']
Single levels:
Params: ['msl', '10u', '10v', '2t']

I tried to downloaded data with this command

c = cdsapi.Client()
c.retrieve(
'reanalysis-era5-single-levels', # Dataset name
{'date': 20230110,
'time': 0,
'param': ['msl', '10u', '10v', '2t'],
'level': ['1000', '925', '850', '700', '600', '500', '400', '300', '250','200', '150', '100', '50'],
'param': ['z', 'q', 't', 'u', 'v'],
'grid': [0.25, 0.25],
'area': [90, 0, -90, 360],
'product_type': 'reanalysis'
}, 'Output.grib')

But I got a job failed error.

I am able to download if I comment out this line
#'param': ['z', 'q', 't', 'u', 'v'],

But then I get this error when I run the model
ValueError: cannot reshape array of size 0 into shape (5,13,721,1440)

Please help.

I realized the mistake in my cdsapi call and I changed to
c = cdsapi.Client()
c.retrieve(
'reanalysis-era5-single-levels', # Dataset name
{'date': 20230110,
'time': 0,
'level': ['1000', '925', '850', '700', '600', '500', '400', '300', '250','200', '150', '100', '50'],
'param': ['z', 'q', 't', 'u', 'v'],
'variable': ['msl', '10u', '10v', '2t'],
'grid': [0.25, 0.25],
'area': [90, 0, -90, 360],
'product_type': 'reanalysis'
}, 'Output.grib')
With this I was able to download the data but I still get this error when I run the model
ValueError: cannot reshape array of size 0 into shape (5,13,721,1440)
