I am new to ArcGIS. I have a list of cities and their longitude/latitude (as a .csv). I have another .tiff file which contains a map of the world records values on a 5' x 5' grid cell (this is the data: https://ozak.github.io/Caloric-Suitability-Index/).

I am now trying to match my cities to the average value of the .tiff data in a 50km radius around the city. I would like to export the data as a .csv or something similar with an added column for the average value.

I've pulled both datasets up in ArcMaps but I cannot figure out how to overlay, calculate the average and then export the data again. Could someone point me in the right direction?

Thank you very much already, I know this is a beginner's question. I hope to get more proficient soon but I have to solve this problem in the short-term.

Best,

cfr
