Η ερευνητική ομάδα της Επιχειρησιακής Μονάδας BEYOND του Εθνικού Αστεροσκοπείου Αθηνών εκπόνησε το παρόν report με στόχο την καταγραφή και ανάλυση των δασικών πυρκαγιών που έπληξαν την Ελλάδα κατά τη θερινή περίοδο του 2025. Κατά τη διάρκεια αυτής της περιόδου, το Πυροσβεστικό Σώμα κατέγραψε μεγάλο αριθμό περιστατικών, ενώ το European Forest Fire Information System (EFFIS) της Ευρωπαϊκής Επιτροπής χαρτογράφησε 49 πυρκαγιές με καμένη έκταση άνω των 50 εκταρίων. Η ομάδας μας, αξιοποιώντας δορυφορικά δεδομένα Sentinel-2 του Ευρωπαϊκού Προγράμματος Copernicus EU, με χωρική ανάλυση έως 10 μέτρα για την ακριβή χαρτογράφηση των καμένων εκτάσεων και μέσω της ανάλυσης χρήσης γης στις πυρόπληκτες εκτάσεις με δεδομένα του CORINE Land Cover 2018 και εκτίμηση της επικάλυψής τους με το δίκτυο προστατευόμενων περιοχών NATURA 2000, παρέχει μια ολοκληρωμένη εικόνα των επιπτώσεων των πυρκαγιών για το καλοκαίρι του 2025.

Following the successful organization of IGARSS 2024 in Athens, The Operational Unit “BEYOND Centre of Earth Observation Research and Satellite Remote Sensing” of the National Observatory of Athens (NOA), actively contributed to IGARSS 2025 with a high-level session organization and participation, oral presentations, and posters. The International Geoscience and Remote Sensing Symposium (IGARSS) 2025, the flagship conference of the IEEE Geoscience and Remote Sensing Society (GRSS), took place on 3–8 August 2025 in the vibrant city of Brisbane, Australia. With the theme “One Earth”, this year’s edition highlighted the urgent need to address global environmental threats and to foster collaborative solutions through remote sensing and Earth observation technologies.

The Mediterranean region is facing an alarming rise in the frequency and severity of wildfires, threatening ecosystems, communities, and livelihoods. In response, BEYOND Centre of Earth Observation Research and Satellite Remote Sensing (BEYOND/NOA) is proud to coordinate the MedFireWise Project—a new, ambitious 36-month project under the Interreg NEXT MED programme aimed at advancing wildfire risk management across the Mediterranean basin.

Launched on June 18, 2025, and co-funded by the European Union, the MedFireWise Project promotes Nature-based Solutions (NbS)—namely prescribed burning and silvopasture—as sustainable and scientifically supported practices to mitigate wildfire risk and strengthen ecosystem resilience.

We're excited to announce that the successful collaboration between our team from NOA/BEYOND, NTUA, and IDCOM, under the supervision of JRC CEMS, has resulted in valuable scientific insights on post-wildfire vegetation recovery surveillance in Sierra Bermeja, Spain. State of vegetation and forest mass, erosion risk, landslide risk and road network accessibility mapping were assessed in order to monitor the recovery of the environment and to provide information on the risk to accommodate the use and services of the impacted territory.

The Operational Unit “BEYOND Centre of Earth Observation Research and Satellite Remote Sensing” of the National Observatory of Athens (NOA), in collaboration with the PRAXI Network/FORTH, co-organised a two-day event in Tbilisi, Georgia, on July 8–9, 2025, with the support of the Georgian National Environmental Agency, in the framework of the European FPCUP programme (Caroline Herschel Framework Partnership Agreement on Copernicus User Uptake).

A workshop was held on July 8, followed by a hands-on session on July 9, to address the significant challenges posed by natural disasters in Georgia, while introducing the Copernicus services that support monitoring and provide critical information on floods and wildfires.

Σκοπός της ανάλυσης

Το υδροδοτικό σύστημα της Αττικής αντλεί νερό από τέσσερις βασικούς ταμιευτήρες: Μόρνος, Εύηνος, Υλίκη, και Μαραθώνας. Από αυτούς:

• Ο Μόρνος είναι η κύρια πηγή ύδρευσης, εξυπηρετώντας τη μεγαλύτερη κατανάλωση.
• Ο Εύηνος ενισχύει τον Μόρνο μέσω της σήραγγας Ευήνου-Μόρνου, λειτουργώντας ως μεταβατικός ταμιευτήρας.
• Η Υλίκη (φυσική λίμνη) και ο Μαραθώνας λειτουργούν συμπληρωματικά στους δύο κύριους ταμιευτήρες.

Η υπηρεσία FloodHUB της Επιχειρησιακής Μονάδας BEYOND του ΙΑΑΔΕΤ/ΕΑΑ εκπόνησε διαχρονική αξιολόγηση των υδρολογικών και κλιματικών συνθηκών στους δύο βασικούς ταμιευτήρες που υποστηρίζουν το υδροδοτικό σύστημα της Αθήνας —τον Μόρνο και τον Εύηνο— ώστε να εκτιμηθεί ο βαθμός υδρολογικής πίεσης και ξηρασίας στο σύστημα για πρώτο εξάμηνο του 2025.

BEYOND/NOA proudly serves as Greece’s National Operations Center (GR-NOC SST) and as a key contributor to the European SST Partnership (EUSST).

From detecting and cataloguing space objects to supporting critical services like Collision Avoidance, Re-entry Analysis, and Fragmentation Monitoring, our mission is to safeguard the orbital environment and ensure the long-term sustainability of space activities.

The journey of the Early Warning System for Mosquito-Borne Diseases (EYWA) was presented during the WOAH Regional Seminar on "Vector-Borne Diseases in the European Region," held from 25 to 27 June 2025 in Teramo, Italy.

The event was jointly organized by the World Organisation for Animal Health (WOAH), the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise “G. Caporale” (IZS Teramo), and supported by the European Commission's Directorate-General for Health and Food Safety (DG SANTE). It provided a critical platform for discussing the challenges and developments related to vector-borne diseases (VBDs) across Europe and neighboring regions.

BEYOND Centre of Excellence of ISAARS/NOA made a dynamic mark at this year’s Living Planet Symposium 2025, hosted by the European Space Agency (ESA) in Vienna, from the 23rd to the 27th of June. As one of the world’s premier Earth Observation (EO) forums, the event gathered leading scientists, institutions, and space stakeholders to share breakthroughs in environmental monitoring, Artificial Intelligence (AI), and satellite technologies.

Kicking off the Centre’s presence, Dr. Haris Kontoes, Research Director at IAASARS/NOA, presented groundbreaking work on Leveraging Earth Observation Data and Explainable AI for Predicting Mosquito-Borne Disease Outbreaks (Session B.03.06), underscoring the growing role of AI in public health surveillance.

CEMS Activation: Forest fuel mapping and fire hazard in France

We're excited to announce that the successful collaboration between our team from NOA/BEYOND, NTUA, and IDCOM, under the supervision of JRC CEMS, has resulted in valuable scientific insights on forest fire risk assessment in northeastern France.

Structural vegetation layers relevant for fuel mapping were generated using LiDAR and aerial imagery, and fire hazard maps were produced by analyzing meteorological scenarios to assess wildfire risk.
