URBAN CLIMATOLOGY Map of the local climate zones
practical excercise
Local Climate Zones - basic premises
• Urban climate is highly variable in space and time
• If we want to study the urban climate, we need to classify it somehow
• One of the main factors that create a characteristic urban climate are fabric (materials), land cover, structure and metobolism.
• Land cover mapping can serve as a basis for urban climate classification
• In urban climatology, the concept of the Local Climate Zones was
created during the last decade

What can LCZs be useful for?
Excercise - LCZs mapping
Motivation: Land cover types and spatial structure of built-up areas, which can be directly seen on aerial photographs, well correlate with typical features of local climate in urban environment.
Tasks:
1. Learn about the concept of Local Climate Zones and its classification system
2. Choose a larger city that you are at least familiar with, for example your capital city
3. Use Google Earth map or some other internet map source (www.mapy.cz) and find a typical representative of individual LCZs in Your city (two typical snapshots).
4. Characterize each LCZ briefly - where it occurrs (w.r.t. the city centre), is it rare or quite common LCZ, ... key words
5. Describe typical LCZs that are well represented in Your city. Mention those LCZs that do not occur in Your area.
https://is.muni.cz/auth/el/sci/podzim2022/ZX601/um/exercise/Local climate zones.pdf
Output no. 1- „training sites" for LCZs mapping
Draw 1-3 polygons that well represent individual LCZs in Your city. See Figure below as an example. In Google Earth You can add the legend (LCZ types with selected color) as follows:
Right click on
My places -> Add -> Folder
Create name of the of the folder - e.g. LCZ3 Then right click on LCZ3 folder
LCZ3 -> Add -> Polygon
Create name of the polygon (e.g. Site_3_l) and select color of the polygon, do not close window and place mouse over the map.
Find suitable place - left click defines polygon outer points, right click close the polygon Repeat for 2-3 polygons for each LCZ
Now create folder for another LCZ - e.g. LCZ4 and repeat as above
Alternatively, You can create only the polygons (without folders). In this case You need to add proper names to individual polygons (see example-figure below)
Finally save Your map as follows: File -> Save -> Save folder My places
This creates file My places.KMZ on Your computer.
Make also a simple print screen of Your map.

Output no. 2- LCZ overview
When finished, write a report shortly discussing:
1) Which LCZs can be easily found (are typical) in Your city according Your opinion;
2) Which LCZs do not exist in Your area or which are hard to recognize
Besides the text, the final report will include the LCZ map (e.g. printscreen) and a short description of typical LCZs in Your city:
LCZ2 - compact mid-rise:
short paragraph with the LCZ characteristics
LCZ5 - open mid-rise:
Output no. 3- „positive" and „negative" sites
Select in Your city two sites representing according to You
1) A part of the city that contributes to reducing the negative effects of
climate change on the urban climate
2) It is a part of the city that, on the contrary, amplifies the negative effects of climate change on the urban climate
3) Suggest what realistic climate change adaptation measures could be done in your city.

Excercise - final notes
• Prepare short PPT presentation (10-15 minutes)
• At the last meeting on December 4th, you will inform us of your results
