Step 1 of 2Read the paper
Using satellite land surface temperatures and land-cover maps for 293 European cities, this study estimated how much cooler areas fully covered by urban trees or treeless green space are than dense built-up areas. Statistical models fitted for each city and image let the authors compare regions, seasons and hot extremes, and link patterns to evapotranspiration and albedo.
How to read it
- Read the last Introduction paragraph and Fig. 5 together: they explain what the models predict and subtract.
- Keep LST (surface) and air temperature apart; the Discussion explains why they differ.
- In Results, compare median summer cooling with cooling during hot extremes for each region (Fig. 2c).
- List the limitations in the Discussion: timing, clouds, missing street trees, and shading not captured.
