How to match up IDW pollution levels to new geocoded address.

[GillianGoobie]

Using inverse distance weighting (IDW) of air pollution levels to estimate the air pollution experienced at someone's house. I have created a map with all the air quality monitoring stations in the Northeastern U.S. as location points, and a layer of the average PM2.5 level measured at each of those stations from 1999-2019. I have individual geocoded addresses that I want to document an estimated number for cumulative PM2.5 exposure, based on my previous IDW interpolation, but I am not sure how to match up a PM2.5 value with each individual geocoded address. I have added in the individual geocoded address data as another layer, but I am not sure where to go from here. Please help!
