message_ix_models.tools.iea.web.transform_C

message_ix_models.tools.iea.web.transform_C(qty: TQuantity) → TQuantity[source]

Compute data for some additional “flow” codes related to transport.

In the source data, values for flow="AVBUNK" are negative. Populate data for flow="_1" and flow="_2" such that:

\begin{array}{r} X_{_1} = X_{D O M E S A I R} - X_{A V B U N K} \\ X_{_2} = X_{T O T T R A N S} - X_{A V B U N K} \end{array}

The resulting values for, for instance, $X_{_1}$ are larger in magnitude than the values for $X_{D O M E S A I R}$ , because a negative number is subtracted.
