Introduction about Field Survey and Measurement
9 students are divided into 3 groups. Each group is assigned one site in 300m*300m size to do the sustainable urban design. Student can do the field survey of urban
morphology of their sites at any time, while the field measurements need to be conducted on March 1 from 14:00 to 16:00. Each group will take 1 set of TESTO 400
and 1 set of HOBO U12 to measure the climate parameters. 8 measurement points have been assigned for field measurement of each group. Each group need to
spend 10 minutes at one point, and use 5 minutes to move to the next point. The total measurement time of 8 points is 2 hours. Details about the site location and
measurement points can be referred to the following part.

Wind Direction: Wind direction need to be measured manually. For example, southeast wind direction means wind came from southeast direction at that time.
Students only need to record the start time and prevailing wind direction of each measurement point (fill in the green column in the table), and the climatic data
such as air temperature, RH, wind speed measured will be recorded automatically by TESTO and Onset HOBO (HOBO is only used for backup, and it can only record
air temperature and relative humidity data). The measured climatic data will be read out after the measurement through computer.
