ur Aeronomy Lab, constructed in the Winter 2006 - Spring of 2007, sits atop the Administration Building on the CCNY campus to gather air quality data. The 140 sq ft structure is fully insulated to provide a temperature controlled environment for sensitive instrumentation and provides workspace for additional specific-goal research projects.

PM 2.5 (particulates) and O3 (Ozone concentration) Data can be retrieved here. The New York State Department of Environmental Conservation operates equipment in our lab to gather and report this concentration data representing particulates 2.5 micrometers (2.5μ) in size or smaller aerodynamic diameter. Since airborne particles have irregular shapes, their aerodynamic behaviour is expressed as the diameter of an idealised spherical particle known as aerodynamic diameter.

Reports, graphs and downloads in various formats can be produced along with comparisons of data from nearby Metropolitan New York sites. Select the 1024x768 screen size to view properly in your browser when extracting comparison graphs.

CCNY operates additional instrumentation for research purposes, continuously monitoring the following air parameters:
