A help Tutorial: Estimating health impacts of the Volkswagen emissions scandal

[Yahui Bian]

This blog post contains a step-by-step example of how to create an emissions scenario and use the InMAP model to estimate the resulting health impacts. I think it is very kind for a beginner. 

However, there is outdata for the web (See the figure), so I can not do next step. Thus, can you  update the web, or put a another case for health impacts based on InMAP model?

Thank you very much. Looking forward to your reply.

Hi Yahui,

I am actually having the same question. Does anyone know where we can find the data file so we can try replicating the tutorial?

Thanks,

Anil G.

Still looking for the data :(

Here you can download the 2019 on-road emissions shapefiles. It includes NOx, NH₃, and primary PM₂.₅. The units are in μg/s:

It looks like the pcloud link has expired. And the author of the post may be out of the country by now (based on his LinkedIn page). Someone with access to the shapefile in the tutorial may be able to provide a new link! 

In the meantime, if you are willing to convert the data yourself from the original NEI data as a workaround for the missing shapefile, I can take a stab at some general instructions. Happy to get corrections/edits. Note that this will require a moderate amount of spatial data manipulation and the use of python to convert NEI CSV files to shapefiles. 

The write-up was getting lengthy, so I put it in a google doc here:

You can use the 2019 emissions data for the tutorial. Here is the link for the 2019 On-road emissions shapefiles:

It includes NOx, NH₃, and primary PM₂.₅. The units are in μg/s.

Sorry, I meant to respond to the previous message, not your message -- I meant that the pcloud link in the original tutorial has expired. The data you are sharing may be a viable way to start.

I was trying to help any reader that wanted to get as close as possible to the emissions data that was used in the tutorial so they might be able to compare their result to tutorial result. Because the distribution of on-road emissions changes from year to year, I think it makes most sense to use on-road emissions from within the study period (2008-2015). 

That being said, the tutorial uses only one on-road emissions shapefile for all eight years, so it's probably meant to be more of a proof-of-concept exercise, not a robust result. Using your emissions file also seems like a good way to get the tutorial example working :)

I see, thank you for pointing that out. We may consider modifying the tutorial in the future to work with the new emissions data.

Thanks, all. Just to clarify, we don't have / can't find the original data, but the data Hamid posted should work as a replacement (let us know if it doesn't). I've updated the link in the source code for the website, but because compiling and updating the live version of the website is a lengthy process which is not as automated as it should be, we haven't done that yet.
