Questions about the input and output of 2005_emissions

[steven H]

Hi everyone,

Thanks for sharing the documentation about Inmap on GitHub. I'm pretty new to using geographic modeling software and don't have much knowledge about chemical or environmental studies. After studying for a few days, I ran the code for 2005 emissions and got the results, but I still have a few questions I'd like to ask.

1. I'm a bit confused about the role of "InMAPData_v1.3.0.gob" and "InMAPData_v1.2.0.ncf". From what I understand, InMAP takes the input of different gas emissions in 2005 and calculates the concentration/content of different gas components (such as PM2.5) and mortality rate through various conversions. The "Readme.txt" mentions that the '.ncf' file is the output of the chemical model WRF, in my understanding, maybe the file provides some parameters for Inmap from input to output equations. I've also read the original paper of Inmap, but my knowledge in this field is limited. Can you explain the role of WRF output (.ncf) and ".gob" files in simpler terms?

2. In the "nei2005Config.toml" , "census2013blckgrp.shp" and "mortalityRates2013.shp" are also included, which contain the population data and mortality rate in 2013. Can I assume that in order to simulate the impact of PM2.5 on people's health in 2005, the population in 2013 is used as the population data in 2005, and the mortality rate in 2013 is used as the baseline mortality rate to establish the functional relationship between PM2.5 and the increase in mortality rate for calculating the mortality rate in 2005?

3. Since I'm a novice, if I want to create a dataset myself (for example, studying the impact of LA gas emissions on people's health in 2023) for simulation, can you recommend some tutorials on how to construct such data?

Thanks a lot for your help!
