Data analysis - Autumn tree campaign

2023-12-03T21:43:16Z

Tree: Tilia platyphyllos

Latitude: 44.11105°
Longitude: 15.23009°
Elevation above sea: 19 meters
Yearly average temperature: 18.5°C
The wettest month in Zadar is November.

The soil temperature on the first day of measurement was 34.3°C and the last day of measurement was 8.4°C.
Leaf surface temperature (20.9.2023.):
- leaf 1: 33.1°C,
- leaf 2: 33.5°C,
- leaf 3: 33.4°C,
- leaf 4: 33.8°C.
Leaf surface temperature (21.11.2023.):
- leaf 1: 9.7°C,
- leaf 2: 9.3°C,
- leaf 3: 9.5°C,
- leaf 4: fallen.

Because of the higher average temperature this year in Zadar, not all leaves fell off or completely changed color.

When we compare our results with the results of the Elementary School Veli Vrh in Pula for the tree Tilia cordata, we notice that their leaves changed color a bit more and did not have a same transition between dark green and lighter yellow.
