Getting ready

For this recipe, we will need to import the NumPy package as np, the Pandas package as pd, the Matplotlib pyplot module as plt, and an instance of the default random number generator from NumPy:

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from numpy.random import default_rng
rng = default_rng(12345)

We also need to import the xarraypackage under the aliasxr. You will also need to install the Dask package, as described in the Technical requirements section, and the NetCDF4 package:

import xarray as xr

We don't need to import either of these packages directly.
