Platform and Components
CityCLIM has developed the Generic City Climate Platform, which handles the backend and is open to the integration of further components and services. Components already developed are data processors that integrate and harmonise data sources with space, in-situ and airborne data, and engines that process this data for use in services. Let's find out.

Generic City Climate Platform
Ein einheitliches Backend für städtische Dienste
Um die identifizierten Interessensgebiete abzudecken, zielte das CityCLIM-Projekt darauf ab, zwei Sets von Minderungs- und Anpassungsdienstleistungen bereitzustellen, um den Effekt urbaner Wärmeinseln und anderer mit dem Klimawandel verbundener Gefahren anzugehen. Diese beiden Sets richten sich an unterschiedliche Interessengruppen innerhalb einer Stadt: die breite Öffentlichkeit und Entscheidungsträger in jeder Region.
Generische Stadtklimaplattform
Die Generic City Climate Platform (GCCP) ist eine skalierbare Multi-Cloud-Lösung und der zentrale Softwareteil des CityCLIM-Ökosystems. Sie übernimmt die Orchestrierung und Verwaltung der Arbeitsabläufe, die für die Verarbeitung verschiedener Datentypen (z. B. Wetterstationen, mobile Sensoren, Erdbeobachtung, Luftaufnahmen, Modelle usw.) erforderlich sind und die Grundlage der City Climate Services bilden.
Alle Dienste werden über eine moderne SaaS-Lösung bereitgestellt: die Generic City Climate Platform (GCCP). Diese Plattform sammelt alle Eingangsdaten für die Diensterbringung, vereinheitlicht und verarbeitet sie weiter und stellt eine Vielzahl sogenannter „Engines“ bereit, die die relevanten Ausgaben aus dem Wettermodell und anderen Dienstkomponenten generieren.
Das GCCP ist jedoch nicht nur ein reines Tool zur Datenerfassung und -verarbeitung, sondern bietet auch ein benutzerzentriertes Frontend, das seinen Abonnenten den visuellen Zugriff auf alle Dienste über ein intuitives Dashboard ermöglicht. Darüber hinaus bietet das GCCP einen API-Endpunkt für alle teilnehmenden Städte, sodass die Ergebnisse einiger Dienste (z. B. der Citizen Climate Knowledge Services) auch direkt abgerufen werden können und jede Stadt individuell entscheiden kann, wie sie diese Dienste auf ihren eigenen öffentlichen Plattformen für ihre Bürger anzeigen oder integrieren möchte.

Airborne Data Processor
The Airborne Data Processor leverages RAVEN’s high-resolution thermal infrared capabilities to bridge the gap between coarse satellite data and local in-situ measurements, converting airborne temperature readings into precisely geo-referenced datasets that fuel urban climate analysis, validate environmental simulations, and support diverse applications—from infrastructure inspections to vegetation health monitoring.

Spaceborne Data Processor
The Spaceborne Data Processor seamlessly combines raw satellite imagery from Sentinel-2, Sentinel-3, and Landsat 8/9 into actionable climate insights across its three modules: the Spaceborne Data Preprocessor (which automates and harmonises data collection), the Thermal Sharpener (which produces high-resolution thermal data in an operational way using the ESTARFM and ATPRK sharpening methods by integrating both spatial and temporal variability into the model), and the Index Calculator (which generates critical heat indices as UHS, SUHI, UFTVI, UHIER or DI).

Engines
Forecast Engine
The City Climate Forecast Engine orchestrates the operational workflow of the UltraHD Weather Model by regularly providing the latest in-situ observations and static boundary conditions to initiate forecast runs. It continuously monitors model status, tracks simulation progress, and ensures all resulting UltraHD data sets are archived in the data warehouse for easy service access. Beyond its operational role, the Forecast Engine also enables visualisation by generating map overlays and time series from the data warehouse, granting stakeholders a detailed and up-to-date view of localised weather patterns and trends.

Simulation Engine
The City Climate Simulation Engine provides on-demand execution of the UltraHD Weather Model Processor by organising boundary conditions and other input data within the data warehouse into clearly defined scenarios. Working closely with the City Climate Services, it uses user-modified Inputs - such as land use changes, updated digital elevation models, or varying emissions - for scenario-based modelling. Leveraging these scenarios, the Engine then triggers UltraHD model runs, closely monitors their progress, and keeps users informed of the simulation’s status, ensuring that each forecast and climate assessment is both accurate and tailored to evolving urban configurations.

Diagnostics Engine
The City Climate Diagnostics Engine performs statistical analysis over selected operational runs of the Advanced Weather Model Processor. That includes calculation of minimum, maximum and mean values for different output parameters regarding environmental aspects in relation to heat, airflow, and pollution. The Diagnostic Engine is the main component that serves the Identification Services with on-demand analysis capabilities.

Citizen Weather Sensation Engine
The Citizen Sensation Engine for Personalised Climate & Weather Feeling acknowledges that individual comfort levels can vary significantly depending on factors such as health status, cultural background, and personal tolerance to temperature and humidity. By drawing on real-time data for variables like air temperature, relative humidity, and heat index, the engine generates a traffic light-coded city map—areas exceeding all comfort thresholds appear in red, those exceeding just one appear in yellow, and those remaining within the chosen ranges are marked green. Users can customise which weather parameters to include and see their own location highlighted according to their comfort zone. With this tailored approach, the engine helps citizens make informed decisions about where to go and what activities to plan, ensuring a more comfortable and health-conscious urban experience.

D4.4 Optimised Full Prototype of Citizens Science Concepts for Urban Climate Monitoring
EO-based Heat Island Mitigation and Simulation Service Engine
The engine leverages standard Earth Observation (EO) data to estimate how urban modifications (e.g., adding vegetation or altering building configurations) affect local land surface temperatures. By applying a neural network trained on both typical and extreme summer-day datasets, the engine generates near-instantaneous heat impact scenarios, empowering city planners and the public to evaluate multiple mitigation strategies before they are implemented. Thanks to its reliance on readily available EO data, the engine remains both cost-effective and easily transferable to any urban area, making it a versatile tool for advancing climate resilience and informed urban planning.
