Urban site analysis includes tangible factors such as the physical site features and intangible factors as the sensory site features like odors affect the inhabited area in the site. Environmental and chemical studies have much greater attention and studies to the odor effects in the urban areas than urban designers. The aim of this paper is to provide a validated and applicable method for the urban designers in odor measurement. The objective of this research is to present the various methods in measuring odors adopted in chemical and environmental studies to achieve an applicable odor measurement method in the urban design field. The odor measurement tools are usually dedicated to measure odor concentration at the odor source or at the receptor location, that are used in chemical and environmental studies. However, in the urban design studies the odor measurement could be performed using a method called the citizen science considering the FIDOL factor to evaluate the odor nuisance including odor frequency, intensity, duration, offensiveness, location, and hedonic tone. This research conducts a case study in a coastal area in Tripoli city and determine Tripoli landfill as a significant odor source that affect people in their inhabited areas. A questionnaire were distributed in the affected area by the odor source, and the respondents of the inhabitants ensured that the summer season is the most season that they can feel the odor in their places be associated with the wind direction. The results ensure that the citizen science method in measuring odors is validated, applicable, and available for urban designers to detect and estimate the affected area by odor source.
