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-Based Heat Island Identification service
University of Valencia’s EO-Based Heat Island Identification service is now available for usage, providing 30-m daily LST data for the four pilot cities registered in CityCLIM.
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

The Surface Urban Heat Island Index map for June 14 over Valencia shows how important are parks and water bodies for the heat regulation on urban areas. Where the park area near Ciudad de las Artes y las Ciencias exhibits temperatures 5 degrees lower than the average temperature of the city.
We conducted an extensive field campaign in Valencia to measure Land Surface Temperature (LST) at various locations across the city. These ground-based measurements are intended to validate and enhance the accuracy of satellite imagery captured by OHB’s Raven sensor.
​
By comparing the field data with the satellite-derived LST, we aim to refine the calibration of the sensor, ensuring more reliable results. This improved data will serve as a critical input for a range of urban heat studies, providing valuable insights into local heat island effects, thermal comfort assessments, and urban planning initiatives aimed at mitigating extreme heat conditions.

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.

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.
