City Climate Services
The City Climate Services represent all the services developed within the CityCLIM project. They are divided into two main groups:
-
City Administration Services support city administrations and urban planners in designing and testing mitigation strategies for climate change related impacts (heat, pollution, air flow) in their cities.
-
Citizen Climate Services inform, warn and engage citizens in mitigating climate change related weather impacts.

City Administration Services
The Identification Services enable users to perform statistical analysis on aggregated climate-related data drawn from the CityCLIM ecosystem. These services include the Heat Island Identification Service, the UltraHD-based City Air Flow Identification Service, and the UltraHD-based Pollution Area Identification Service. Each service is equipped with a graphical interface allowing users to analyze urban areas regarding different environmental parameters, identify sources of fresh air, and detect regions that tend to accumulate pollution. These are integral in understanding the environment of a city and how air and pollution are transported within. To complement identification services, a set of Simulation Services has been conceptualized, including the Heat Island Simulation and Mitigation Strategies Service, the City Air Flow Simulation and Mitigation Strategies Service, and the Pollution Simulation and Mitigation Strategies Service. These services grant users the ability to manipulate city models, create simulations to evaluate the impacts on various topics like Urban Heat Islands and city air flows, and receive suggestions for mitigation measures.
Identification Service
The CityCLIM Identification Services stands as a groundbreaking tool for understanding the nuanced atmospheric interplays at play within the confines of urban microclimates. Urban planners, researchers, and city administrators often grapple with the intricate dance of various climatic factors that dictate the living conditions in cities. With increasing urbanization, the need to comprehend and manage these microclimates becomes paramount. CityCLIM’s ability to tap into past UltraHD model runs (given an appropriate runtime) provides a rich data basis, enabling professionals to delve deep into historical local climatic patterns, understand temperature anomalies, and even compare specific areas within a city based on selected parameters.

EO-basierter Wärmeinsel-Identifizierungsdienst
Der auf Erdbeobachtungen basierende Dienst zur Wärmeinselidentifizierung der Universität Valencia steht nun zur Nutzung bereit und bietet täglich 30-m-LST-Daten für die vier in CityCLIM registrierten Pilotstädte.
EO-Based Heat Island Identification service
The 30-m LST is being produced fusing data from multiple thermal sensors onboard satellite platforms reaching an accuracy of around 1ºC and reproducing the spatial patterns recorded by medium and high resolution termal images
Das 30 m lange LST wird durch die Zusammenführung von Daten mehrerer Wärmesensoren an Bord von Satellitenplattformen hergestellt, erreicht eine Genauigkeit von etwa 1ºC und reproduziert die räumlichen Muster, die von Wärmebildern mittlerer und hoher Auflösung aufgezeichnet wurden.
Die Karte des Surface Urban Heat Island Index vom 14. Juni über Valencia zeigt, wie wichtig Parks und Gewässer für die Wärmeregulierung in städtischen Gebieten sind. Dabei weist der Parkbereich in der Nähe der Ciudad de las Artes y las Ciencias Temperaturen auf, die 5 Grad unter der Durchschnittstemperatur der Stadt liegen.
Wir haben in Valencia eine umfangreiche Feldkampagne durchgeführt, um die Landoberflächentemperatur (LST) an verschiedenen Standorten in der Stadt zu messen. Diese bodengestützten Messungen sollen die Genauigkeit der vom Raven-Sensor von OHB erfassten Satellitenbilder validieren und verbessern.
​
Durch den Vergleich der Felddaten mit dem satellitengestützten LST möchten wir die Kalibrierung des Sensors verfeinern und zuverlässigere Ergebnisse erzielen. Diese verbesserten Daten werden als wichtiger Input für eine Reihe von Studien zur städtischen Hitze dienen und wertvolle Einblicke in lokale Wärmeinseleffekte, Bewertungen des thermischen Komforts und städtebauliche Initiativen zur Abmilderung extremer Hitzebedingungen liefern.

Simulation Services
The CityCLIM solution includes a Simulation Editor that allows users to simulate local urban characteristics by adapting land cover types and elevation. The user can create a new set of simulated changes by drawing polygons of different colors representing different land cover types on a map. Clicking on the polygons allows the user to additionally enter elevation information. Every added information on the map is automatically saved, and already integrated changes can be reviewed and continued. Moreover, the user can request a simulated run by specifying a reference period, which then triggers the workflows of the simulation engine to produce manipulated EO data.
The user can request on-demand model runs. The service then calculats differences for certain parameters and model runs and produce maps using this data to study the influence of changes in land use or the digital elevation model.

Citizen Climate Services
Services that are targeting the general public.
Heat Sensation Service
Pilot City Luxembourg
The individual weather map uses the heat index. The "comfort temperature range" that the user can select and which is displayed on the map already takes into account the air temperature and relative humidity. This way, a more accurate idea can be conveyed of how hot it actually is for a person. In our blog post on the CityCLIM website, you can find further information about individual weather perception.

Pollution Information Service
Valencia
The pollution information service is aimed at citizen and city administration stakeholders to monitor the air quality in the region and the distribution and movement of important air quality parameters. It is available as a web widget to be implemented in "foreign" websites and also available in the CityCLIM frontend. The pollution information service is available for 4 air quality parameters: Ozone, Particulate Matter, Nitrogene Dioxide and Nitric Acid.

Heat Wave Information
Karlsruhe
As part of the EU project CityCLIM, the weather forecast for Karlsruhe as a pilot city is calculated daily using grid cells of 100x100 m. The high resolution allows fine structures to be seen within the city, and Karlsruhe can also be seen as an urban heat island during heat waves. The colors in the map indicate the predicted temperature at 2 meters for the current day. So it is not measured real-time data. In the map you can use the play button to start a simulation throughout the day or click anywhere in the bottom bar to select a specific time.

Climate Portal
Global
In the Climate Portal, you will find measurement data from numerous weather stations that we have processed in various ways. You can search for a weather station using the map or the search mask. We aim to visualize these data through various representations to facilitate the identification of climate trends. Such trends become more discernible with longer and more comprehensive measurement series. Especially with long-term data spanning many decades, you will notice that the temperature trend is upwards. Of course, you can also simply view historical data using these representations.
