←--#1:: . For A, B, C: We are not interested in non-bus-derived emissions. --Jouni 23:11, 18 February 2008 (EET) (type: truth; paradigms: science: defence) |
We need to take account of that the emissions variable is per year and the concenctration variable is in 2020

←--#(number):: . The emissions variable contains all years, but the concentration variable contains the values for 2020. Also, the scenarios are in 2020. So we must extract the 2020 values of the emissions variable. --Alexandra Kuhn 09:59, 21 February 2008 (EET) (type: truth; paradigms: science: defence)

Bus technology variable is "current" and the assessment has its scenarios in 2020.

←--#(number):: . It is good to have the "current" technology because we assume that the technolgoy and the bus fleet do not change from 1997 to 2020. --Alexandra Kuhn 10:02, 21 February 2008 (EET) (type: truth; paradigms: science: defence) ⇤--#(number):: . The version "current" changes all the time. How to know to which time to refer to? --Alexandra Kuhn 10:02, 21 February 2008 (EET) (type: truth; paradigms: science: attack) |
Add "total concentration" as supplementary data to the diagram. ("constant node" in Analytica)

| Argumentation:
←--#(number):: . The total primary PM 2.5 concentration is not only related to the bus emissions so it is not a variable, but the measured data are used to calculate the contribution of the busses (source apportionment) so they are important to know. --Alexandra Kuhn 13:29, 21 February 2008 (EET) (type: truth; paradigms: science: defence)
