PART 1: Field Survey PART 2: Field Measurement

Study Area: High-density Urban Area in Kowloon Peninsula

Study Sites: 3 Sites in 300m*300m size are selected

Number of Groups: 3

Number of Students in each groups: 3

Work to do: Field Survey (collect morphological data) and Field Measurement (collect climatic data)

Equipment for Field Measurement: 1 set of TESTO 400, 1 set of HOBO U12 for each group

Time for Field Survey: Unlimited

Time for Field Measurement: 14:00 – 16:00, March 1, Sunday

General Information

PART 1: Field Survey of Urban Morphological Data

Students can add more morphological parameters into the table based on their study.

Time of Survey: Unlimited

Location of Sites and Measurement Points : Open “Measurement_0301.kmz”Location of 3 Sites Location of 8 Measurement Points

Each group needs to spend 10 mins measure the air temperature, RH,wind speed and velocity using TESTO400 and HOBO U12, and then spend5 mins move to the next point. Total measurement time is around 2 hours.

TESTO 400 Operation

1. TESTO 400 is waiting to start 2. TESTO 400 is logging data.

Testo 400 will be programmed in advance to log data. Students need to check whether it is waiting to start before measurement and whether it is logging data during measurement.

TESTO 400 Operation

Click “OK” to come into the menu/to select functionClick “ESC” to come back

Click “I/O” to turn on/off TESTO

TESTO 400 Operation

HOBO U12

Red light flashes at 1 second interval when it is logging data.

HOBO U12

Students need to fill in the green columns during measurement

Summary

Students need to :

During measurement, 1. Arrive each point on time 2. Record the time when you start measurement at each point 3. Record the primary wind direction at each point 4. Check the equipment is working correctly 5. Take photo of the urban morphology at each measurement point

After measurement , 1. return the equipment on time before 6PM, March 1 to Room 505, AIT to Venessa.

2. Send an email with your measurement table together with the photos of your measurement points to zhengyingsheng@gmail.com, before 12 PM, March 2.

Notice

Carry the equipment very very carefully!!!

Open the sensor of TESTO 400 during measurement.

Arrangement

Each group have 1 set of TESTO 400 and 1 set of HOBO U12.

All 3 groups need to pick up and get familiar with the equipment at 12:40 March 1 Sunday, at Room 505, AIT.

We will come to University Station at 13:00, and arrive sites around 13:30.30 minutes left for each group to get prepared to measurement (14:00) at the sites.

If you have any problems during measurement, contact Venessa.TEL of Venessa: 6156 3716
