About the CTM input data

[Krishnendu Barman]

Hey Everyone,

I have a doubt and something to clarify,

Clarification:

1. The input in the InMap from a CTM (like WRF-Chem), they are used for the "Annual-Average reaction-rate" for different pollutants.

Doubt:

1. Should we use year specific CTM output depending upon our emission inventories, and required InMap simulation,

------ In my understanding there could be three scenarios, for example consider, we want to know the annual change of PM2.5 for 2018, and 2020, and we have an emission inventory created in 2018

-------------a) We can use a CTM output for 2018, for both 2018 and 2020, considering the reaction rates would be similar and the annual meteo trends are similar.

--------------b) We can use CTM output from 2018, but for 2020 we need a have a CTM output from 2018-2020,

---------------c) We need to have the separate one-year simulations for 2018 and 2020, not depending on the time of creation of emission inventory?

Thank you for your help.

Regards,
