Hi

I have tried several methods to extract climate data for a given coordinate, but I only seem to get run time errors. My code is working fine without me trying to specify coordinates.

I have tried also putting the  ct.geo.extract_point(data, lat, lon) at the end without any luck.

Anyone have any idea on how I can modify my code to get data only for my desired location?

Would really appreciate any tips!

import cdstoolbox as ct

variables = {
'Near-Surface Air Temperature': '2m_temperature',
'Eastward Near-Surface Wind 10': '10m_u_component_of_wind',
'Northward Near-Surface Wind': '10m_v_component_of_wind',
'Sea Level Pressure': 'mean_sea_level_pressure',
'Sea Surface Temperature': 'sea_surface_temperature',
'Sea Surface Temperature': 'sea_surface_temperature',
'Eastward Near-Surface Wind 100': '100m_u_component_of_wind',
'Northward Near-Surface Wind 100': '100m_v_component_of_wind',
'Mean wave direction': 'mean_wave_direction',
'Mean wave period': 'mean_wave_period',
'Sea surface temperature': 'sea_surface_temperature',
'Significant height of combined wind waves and swell': 'significant_height_of_combined_wind_waves_and_swell'



}

@ct.input.dropdown('variable', label='Variable', values=variables.keys())
@ct.application(title='ERA5 dataset')
@ct.output.download()
def application(variable):

data = ct.catalogue.retrieve(
'reanalysis-era5-single-levels',
