In the framework of the H2020 project Integrated Arctic Observation System (INTAROS), the assessment and gap analysis of the present Arctic observing system were performed through 4 steps:

- A web-based survey on the characteristics and maturity of the existing and recently exploited (via INTAROS) in-situ and satellite-based observations was undertaken via three questionnaires. The survey was designed to collect homogeneous and consistent information about in-situ and satellite observations across the bio, geo, and chemical spheres.

- Requirements for data characteristics such as data coverage, resolution, timeliness, and accuracy were defined with respect to different application areas: climate, operational services, environmental protection, geo-hazard forecast, research development. These requirements were defined by the users and were specific for each component of the observing system for most in situ data. For some in situ and satellite data, the WMO requirements defined in the OSCAR database (https://www.wmo-sat.info/oscar/requirements) were applied.

- The gaps of the existing Arctic observing system were identified on the basis of the comparison between the data characteristics obtained through the survey and the identified requirements. Moreover, Observing System Simulation Experiments (OSSE) experiments performed using ocean, land and atmospheric models will reveal observational gaps from the perspective of operational and climate monitoring applications.

- A synthesis and assessment of the observing system maturity across the Arctic and across domains was performed on the basis of the information collected through the survey, following the methodology developed in previous EU projects and the discussions with GCOS and WMO.

The main result is the enhanced quality, quantity, accessibility and documentation of existing Arctic observations, which are then ready to be ingested into the multidisciplinary, integrated Arctic Observing System (iAOS).
