example_read_file
In this example we will read in files to a TerraModel show how to plot a 1D profile. First we will import all of the necessary python objects.
from terratools.example_data import example_terra_model
from terratools.terra_model import read_netcdf
import os
import matplotlib.pyplot as plt
Now let's download and read in the example mantle convection model netcdf file and print some summary information.
# Read in the netcdf files.
# Download and cache model
path = example_terra_model()
We can now read the example data into a TerraModel object.
model = read_netcdf([path])
Terra output files are currently written out serially, that is one file per process. Some
users may find it convenient to concatenate files from a dump into a single file using
ncecat, a tool which is available through the NetCDF operators package. Terratools also
supports reading concatenated files model = read_netcdf(file,cat=True).
Plot a 1D average profile¶
We can return a 1D profile of the radial average of a field using:
temp_mean = model.mean_radial_profile(field="t")
And we can get the radii using:
radii = model.get_radii()
And now we can plot the 1D profile.
fig, ax = plt.subplots(figsize=(3, 5))
ax.plot(temp_mean, radii)
ax.set_xlabel("Temperature (K)")
ax.set_ylabel("Radius (km)")
ax.set_title("1D average temperature profile")
print(f"Read files and plotted profile")
plt.show()
Read files and plotted profile
