CENTRAL AEROLOGICAL OBSERVATORY

Their core work

The Central Aerological Observatory (CAO) is a Russian federal atmospheric research institute with deep expertise in characterizing dangerous weather phenomena in the upper atmosphere, particularly icing conditions that threaten aviation. In H2020, they contributed the meteorological and atmospheric science layer to European aviation safety projects — providing real-world data on supercooled large droplet (SLD) environments, the particularly hazardous ice crystals that standard certification regimes historically underestimated. Their value to consortia is their ability to bridge atmospheric physics and aviation safety regulation: they understand both how icing forms in nature and what the certification standards (such as EASA Appendix O) require to demonstrate compliance. This positions them as a scientific ground-truth provider rather than an engineering or avionics actor.

What they specialise in

How they've shifted over time

CAO's two projects run concurrently (both 2019–2023), so the keyword split reflects two parallel research threads rather than a clean chronological shift. Their earlier thematic cluster centred on detection technologies, flight test campaigns, and certification processes — the observational and regulatory-validation side of icing science. The more recent cluster shows a pivot toward 3D numerical simulation, experimental databases, and formalised compliance frameworks (Acceptable Means of Compliance), suggesting movement from empirical data generation toward providing the scientific foundation that underpins computational tools and standardised certification criteria. The trajectory is from field observation toward simulation-validated regulatory science.

CAO appears to be deepening toward the modelling and regulatory-standardisation end of icing science — a future collaborator should expect them to contribute atmospheric datasets and physical ground-truth validation for simulation tools rather than sensor or avionics development.

How they like to work

CAO participates exclusively as a consortium partner — they have not led any H2020 project. This is consistent with their profile as a national institute contributing a specific scientific specialisation (atmospheric icing physics) rather than driving project management or consortium assembly. Despite their modest project count, they have worked alongside 48 distinct partners across 15 countries, suggesting they are embedded in a sizeable European aviation safety research community and are trusted as a reliable specialist contributor rather than a coordination hub.

CAO has built a network of 48 unique partners across 15 countries through just two projects, indicating they joined large, multi-partner RIA consortia typical of Clean Sky and aviation safety research. Their network is European in orientation despite being a Russian institution, reflecting the international nature of aviation certification and the pre-2022 openness of EU research to third-country participants.

What sets them apart

CAO occupies a rare niche: an atmospheric observatory contributing meteorological scientific authority to aviation engineering consortia. Most icing-research actors are aerospace engineers, avionics firms, or certification bodies — CAO brings the atmospheric physics perspective, which is essential when setting realistic SLD envelope definitions for Appendix O certification. For a consortium building a project at the intersection of weather science and aviation safety regulation, they offer a scientific independence that industry partners cannot provide themselves.

Highlights from their portfolio

• SENS4ICE
  Directly targets the certifiable hybrid ice-detection architecture gap in current aviation regulation, placing CAO at the centre of a passenger-safety-critical outcome with real regulatory consequences.
• ICE GENESIS
  Aims to replace the current generation of 3D icing simulation tools used across European aerospace — an infrastructure-level scientific contribution with long-term impact on how icing certification will be conducted industry-wide.
