Autumn 2024 - Activity 1

2024-12-04T18:06:01Z

Greetings from Greece's GLOBE v-School at the European Phenology Campaign - Autumn 2024 and Trees around the GLOBE!
We start taking green-down measurements at the same tree [Autumn '20/Spring '21/Autumn '21/Spring '22/Autumn '22/Autumn '23], an old oak at least 200 years old. Sunday's observation measurements are below.

Local environment
The site is located on the eastern slopes of mt. Olympus, in the heart of broad-leaved evergreens [Quercetalia ilicis] at an altitude of 580m. The area is dominated by shrubs and low-rising trees such as the holm oak [Quercus ilex], Greek strawberry tree [Arbutus adrachnae], kermes oak [Quercus coccifera], strawberry tree [Arbutus unedo], prickly Juniper [Juniperus oxycedrus], etc. Characteristic deciduous species at this altitude include manna ash [Fraxinus ornus], Montpellier maple [Acer monspessulanum], Judas-tree [Cercis siliquastrum], European smoke tree [Cotinus coggygria] and others.

The MUC field code is 0192 and described as closed forest, mainly evergreen, temperate and subpolar needle-leaved, irregularly rounded crowns.

Climate can be described as one of Mediterranean type with continental influence, hot and dry in the summer, while humid and cold in the winter. Its local variations are the result of the impact of the sea and the rugged relief of the region.

Here are some informations about the location:

Happy New Year from Greece GLOBE v-School!

Here in Litochoro on mount Olympus National Park was the 2nd year without snowing at altitude of 400m. There is a lot of snow over 800m. altitude.

All four leaves were recorded as fallen at the same day during a night windy storm at Sunday 6-7 January of 2024. This was the same day as last year's the leaves recorded as fallen (06/01/2022). The colour of all four leaves were 7.5YR 6/4.

Hello GLOBE Community from Greece GLOBE v-School and Happy New Year!

Autumn 2022 - Activity 1
Autumn 2022 - Activity 2

As phenology is considered a sensitive indicator of climate change, we could compare the differences between the Northern and Southern Europe. So, we share our Data versus Time graph for 2022 Autumn - European Phenology Campaign and compare it with Skaistgiris Secondary School in Lithuania.

At 27/10/2022 the Students of Skaistgiris Gymnasium recorded the color of the last leave [2.5Y:6/6]. During their next and last obervation at 19/11/2022 the recorded leaf state was 'snow covered'.
As we mention at our Activity 2, in Greece, the last two leaves are recorded as fallen, today, at 06/01/2022.

2024-12-04T18:06:01Z

Hi everyone! Welcome to European Phenology Campaign - Autumn 2022!

We'll take green-down measurements at the same tree [Autumn '20/Spring '21/Autumn '21/Spring '22], an old Pedunculate oak [Quercus robur] at least 200 years old. The branch we've been observing from '20 has dried so we have selected another southeastern branch at 340cm high [the lowest of this tree]. We are using a kind of aluminum ladder to take observations and we know some safety tips for working at heights ;)
You can check this link for past year's green-down measurements.

Spring 2022 - Activity 1 [Supplementary infos]

2024-12-04T18:06:01Z

Greetings from mt. Olympus - Greece GLOBE v-School!

Execuse me for my late reply, as I mentioned earlier today at the 2022 Autumn Tree (Phenology) Campaign Webinar, the branch of the oak tree which we have been observing from 2020 has dried. We took 8 observations as 'dormant'. I'll continue observing the same tree for the 2022 Autumn and we will try to find a new southeastern branch.

Best regards,
Thanos Theodorakopoulos

Greetings from Greece GLOBE v-School and Tinycore Lab team!
Here is an update on European Phenology Campaign - Autumn 2021. In mt. Olympus rains more than a week now, a steady/intensity rain instead of a hot and dry summer season. A lot of branches and leaves have fallen due to bad weather. We record more than 370 mm of precipitation in eight days until now. The relative humidity is absolute 99% inside fog and stratus clouds. The temperature hovers around 10-12 °C [max:16°C/min:5.5°C LSN] and decreases every day. The days getting shorter and there is less sunlight. The marked leaves of the oak are still green but others already changing colors and have starting to fall. Check below today's measurements.

Thank you Lenka, Dana and Bara,

we 're happy to have you! Here in Greece the weather has already turns cooler..

But how climate change can effects spring and autumn? Global warming have changed the growing season, so, maybe this alteration can lead to leaf senescence delay? Let's mark one more year all these seasonal changes and compare them with past observations!

Happy fall y'all and stay safe!

Good evening Europe!
Here is an update on European Phenology Campaign - Spring 2021. I'm sharing the graph of my tree Green Up measurements:

Here are some informations about the location:
Country: Litochoro, mt. Olympus, Greece

Globe Site: Research Area: LIT-218186S6

Instrument shelter [Atmosphere measurements]: Research Area: LIT-193799S3

Collaboration:
We're trying to compare our tree with a site which is located at an altitude higher than 400 m. Unfortunately this is not possible so we decide to collaborate with Ivano-Frankivsk City Environmental Station [260 m. elev.]. We have found several similarities with the tree [Quercus robur] at the site: Дуб В. The similarities consern the date of budbust [28-04/01-05] and the same leaf length [last measurement 15-05: 62mm and our measurement at 22-05: 61mm].
