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

Project Development

Planning & resourcing: Summer 2008 – May 2009

Preliminary fieldwork: June 16–30, 2009

Consultations with GISS & NYCDOH-MH

Team organization

Development of wiki & monitoring protocols

Beta site fieldwork & refinement of protocols

Weekly team meeting

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

These scatterplots 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 plot depicts the extent to which our readings of surface temperature differ from the air temperature recorded at the DoH monitor.
