Air pollution and public health (AIRCLOUD-APERTUM)

AIRCLOUD-APERTUM will be built upon existing services offering urban climate information of 1×1 km2 spatial resolution and a temporal resolution of one hour. CLARA extends this information with an in-cloud air quality modelling tool for high resolution assessments on the local and micro-scale/street level.

Engage end-users

The service was co-developed with regional authorities and air quality consultants, they have been engaged in several occasions during MUF:s, project meetings and internal activities in order to identify their needs and priorities. A number of meetings and demonstrations has been carried out with potential users of the service including SLB Analys (Stockholm), EERC (Estonia), Sweco (Gothenburg), IVL (Gothenburg) and Ministerio de medio ambiente (Santiago Chile).


AIRCLOUD-APERTUM service is an in-cloud air quality modelling tool based on the air quality system Airviro. The service is used for high resolution assessments on the local level and street level, using Copernicus Climate Change Service C3S_441 Lot3 (URBAN-SIS) data as input and boundary conditions. The cloud service aims at being used in consultancy studies.


  • A cloud service that will have background concentrations, maps, topography and physiography preloaded for a simulation area. The user will be able to set up its own domain, physically separated from other domains on the hard disk.
  • Other data needed such as meteorology and emission data will have simplified interfaces for uploading of information.
  • The user will have a simplified user interface for running smaller environmental studies such as consultancy work but will also, on demand, have access to all the functionality within the Airviro product.

To support its sustainability, AIRCLOUD-APERTUM will exploit a SaaS (Software as a Service) business model.


The main benefit with AIRCLOUD-APERTUM is that it is cloud-based with most data necessary for air quality environmental  impact studies pre generated for the user. This reduces the setup time for a  study and hence the cost of making the study. A typical use case in Rotterdam had an estimated time consumption of 24 hours. To do the same with AIRCLOUD-APERTUM required 20 hour for an inexperienced AIRCLOUD-APERTUM user. Our estimation is that  AIRCLOUD-APERTUM with an experienced user would gain about 50% of the time.


AIRCLOUD-APERTUM is a cost driven service.

The main users will use AIRCLOUD-APERTUM for environmental impact assessments. They need to use the cloud based functionality of AIRCLOUD-APERTUM to make the assessment. The client will pay for the setup of a geographical area covering the study area.
