28 January 2026 OntoClimateAdapt is an ontology designed to provide a formal semantic representation of data related to climate change adaptation research, initiatives, and actions. It enables the standardized description, integration, and interoperable exchange of information to support the development of resilient societies and adaptive capacities in the face of climate change. 1 c0599beca8df55873a1ab061dee64e52c510c6a0 hasUnit hasValue hasBeginning hasEnd adaptedThrough An influence relationship between a phenomenon, process, or event and the systems, entities, or domains that experience its impact. affects A relation indicating that a population density measurement applies to a specific age group defined by a minimum and maximum age. forAgeGroup A causal relationship between an effect (or phenomenon) and the process, or event responsible for its occurrence. hasCause A causal relationship between a phenomenon and the observable processes, events, or conditions that result from it. hasEffect An object property that relates a location to its land surface temperature at a specific time. hasLandSurfaceTemperature An object property that relates a location to an observation representing the number of days during which heatwave conditions occur. hasNumberOfHeatwaveDays Relates a Location to its corresponding PopulationDensity measurement. hasPopulationDensity An object property that links an observation to the temporal frequency at which the observed quantity is defined, measured, or aggregated. hasTemporalFrequency An object property that relates an aggregated observation result to the temporal interval over which it was computed. hasTimeInterval An object property that relates a derived quantitative indicator to one or more events from which the indicator has been computed or aggregated. isDerivedFromEvent The time instant when the temperatue was recorded. measuredAtTime The source of measurement, estimation, or observation through which evidence of climate change is obtained. measuredBy A relation linking an event to the geographical location where it takes place or manifests its observable impacts. occursAt The relationship between a natural or environmental phenomenon and the scientific disciplines that systematically investigate it. studiedBy hasNumericalValue symbol inXSDDateTime A data property that specifies the upper bound of the age range defining an age group. hasMaximumAge A data property that specifies the lower bound of the age range defining an age group. hasMinimumAge A deliberate action, strategy, or intervention implemented to reduce the adverse impacts of climate change AdaptationMeasure A group of people whose ages fall within a specified range. AgeGroup AgeSpecificPopulationDensity A temporal frequency representing the count of occurrences within a calendar year. AnnualFrequency A concrete activity or measure undertaken to reduce the impacts of climate change or increase the resilience of human or natural systems. ClimateAdaptationAction An Environmental Phenomenon that represents a persistent alteration in the statistical properties of the climate system. A computational model that applies mathematical equations to simulate the behaviour of the Earth’s climate system. ClimateModel A large-scale physical, chemical, or biological process that occurs within or across components of the Earth system. EarthSystemPhenomenon A naturally occurring process within the environment arising from interactions among biological, physical, or chemical components. EnvironmentalPhenomenon A meteorological extreme event consisting of several consecutive days of unusually high temperatures relative to local climate norms. Heatwave An adaptation measure that strengthens, upgrades, or redesigns physical infrastructure to withstand climate-related hazards. InfrastructureResilienceMeasure The radiative temperature of the Earth’s land surface at a specific location and time. LandSurfaceTemperature Any atmospheric or weather-related phenomenon that deviates drastically from normal conditions and poses risks to humans, ecosystems, or infrastructure. MeteorologicalExtremeEvent A ground-based facility that measures atmospheric and weather variables such as temperature, humidity, precipitation, and wind. MeteorologicalStation A temporal frequency representing the count of occurrences within a calendar month. MonthlyFrequency A quantitative observation describing the total count of days during which heatwave conditions occur at a given location within a defined time interval. NumberOfHeatwaveDays A governance-led adaptation measure implemented through regulations, policies, legislation, incentives, or planning frameworks. PolicyIntervention A quantitative demographic indicator representing the number of individuals residing within a defined unit area of a geographic location. PopulationDensity A remote sensing measurement capturing key environmental or atmospheric variables of the Earth’s surface and climate system. SatelliteObservation The regularity or recurrence pattern according to which an observation or aggregated value is defined, such as annually, monthly, or weekly. TemporalFrequency A temporal frequency representing the count of occurrences within a calendar week. WeeklyFrequency
