1. Urban Heat Islands
Planning Fieldwork

2. When? The Urban Heat Island is biggest: At night (before sunrise)
In the summer
When there is no wind (<5m/s)
When the sky is clear
When the weather doesn’t change through the night
Look at sunrise and sunset times
Look at weather forecasts – aiming for high pressure

3. What local weather data can we find?
the Met Office ,
- WoW ,
Wunderground

4. How can we sample the temperature of different sorts of areas?
Land Use
How can we sample the temperature of different sorts of areas?

5. Thermometers
Need to be kept in the same place for long enough to adapt to the temperature
If left outside, need to be 1m off the ground and at least 3m from a building
Need to be very careful that the sensor holes aren’t covered
Are weatherproof

6. What safety issues do we need to consider for our fieldwork?
