Minimal Complete Verifiable Example

```python import xarray as xr import cartopy.crs as ccrs from cartopy import feature as cf import matplotlib.pyplot as plt import numpy as np

Opening and reading data

data=xr.open_dataset("heavyrain3.nc") print(data)

lon=data.lon[:] lat=data.lat[:]

lev_2=data.lev_2[:]

rainnc=data.rainnc[17-9]

time=data.time[0]

ax = plt.axes(projection=ccrs.PlateCarree())

rainnc.isel(time=16, lev_2=0).plot.pcolormesh(cmap='Purples',add_colorbar=False);

ax.set_extent([west, east, south, north])

ax.coastlines() ax.add_feature(cf.BORDERS)

plt.savefig("rain31.jpg") plt.show() ```

Relevant log output

python raise ValueError( ValueError: Dimensions {'time'} do not exist. Expected one or more of ('lev_2', 'lat', 'lon')

Anything else we need to know?
