Daytime surface and air temperature of NYC streets adjacent to DOH monitors

Research Questions

How do street level temperatures compare to city monitoring sites? How hot is it on city sidewalks? Can we ID street/neighborhood features that

Data excerpt Sanborn Map

These scatter plots depict the dispersion of air and surface temperatures recorded by PlanetNYC about the reading recorded by the DoH monitor. Points are spaced at 10 yard intervals from the monitoring sites.

This anomaly plot depicts the extent to which our readings of surface temperature differ from the recording at the DoH monitor. We observed that on a hotter day (July 27) the difference was far greater.
