Getting StartedΒΆ
This is a simple example of the basic capabilities of aneris.
First, model and history data are read in. The model is then harmonized. Finally, output is analyzed.
In [1]:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt
import aneris
from aneris.tutorial import load_data
%matplotlib inline
The driver is used to execute the harmonization. It will handle the
data formatting needed to execute the harmonizaiton operation and stores
the harmonized results until they are needed.
Some logging output is provided. It can be suppressed with
aneris.logger().setLevel('WARN')
In [2]:
model, hist, driver = load_data()
for scenario in driver.scenarios():
driver.harmonize(scenario)
harmonized, metadata, diagnostics = driver.harmonized_results()

All data of interest is combined in order to easily view it. We will
specifically investigate output for the World in this example. A few
operations are performed in order to get the data into a
plotting-friendly format.
In [3]:
data = pd.concat([hist, model, harmonized])
df = data[data.Region.isin(['World'])]
In [4]:
df = pd.melt(df, id_vars=aneris.iamc_idx, value_vars=aneris.numcols(df),
var_name='Year', value_name='Emissions')
df['Label'] = df['Model'] + ' ' + df['Variable']
In [5]:
df.head()
