Mapping air quality zones for coastal urban centers

Measurement of Cl2 in coastal urban air

[1] Measurements of Cl2 in coastal urban air were made in Irvine, California from Aug.-Nov., 2005, using negative ion atmospheric pressure chemical ionization with tandem mass spectrometry. Cl2 ranged from <2.5 to 20 ppt with a two month mean of 3.5 ± 3.5 ppt (1s) and an average noon photolysis rate of 44 ppt hr 1 Cl2. Model calculations suggest that Cl2 photochemistry results in an increase of...

TEMMS: an integrated package for modelling and mapping urban traffic emissions and air quality

The Traffic Emission Modelling and Mapping Suite (TEMMS) is a program designed to provide detailed estimates of vehicle emissions on urban road networks, and so act as a precursor to urban air quality modelling. TEMMS is a module of the "Quantifiable City", a more extensive model designed to address questions relevant to urban sustainability. Within the Quantifiable City model, TEMMS interfaces...
