The surveys were conducted in summer 2008 by undergraduate
students at UCSD who were trained prior to the project in survey
techniques and use of questionnaires. Concurrent highly timeresolved
environmental monitoring was taking place locally, in order
to record the microclimatic, noise and air quality parameters the
interviewees were experiencing. To this effect, an enhanced mobile
DEMROES station, mounted on a 2 m high tripod, was installed
temporarily at the survey sites. It was equipped with an Extech 407740
Type 2 sound level metre (at 1.5 m above ground level), a Davis
Instruments anemometer and wind vane at 1.9 m, a Humirel HTM2500
temperature and relative humidity probe at 1.8 m, and a Licor SZ200
pyranometer at 2 m.
