OPAS service coordinates the OPAS SO2LH notification service which allows subscribed users to receive information about the height of volcanic plume (emission of sulphur dioxide - SO2 - from an erupting volcano) and the associated contamination of flight level (FL).
The user receives email notifications that provide access to datasets of SO2 layer height (SO2LH) from 3 satellite instruments (via https connection). These datasets are characterised based on metadata.

Since its creation in 1964, the main tasks of the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) are research and public service in the field of space aeronomy, which includes the study of the physics and chemistry of the atmospheres of the Earth and other planets, and of outer space (www.aeronomie.be). BIRA-IASB has strong expertise in designing and operating instruments and experiments to monitor atmospheres and space environment. It has also developed a strong know-how in the exploitation of measurements from ground, air and space, as well as their geophysical interpretation using, among others, theoretical and numerical models.

The context is the development of a notification service which provides near real-time (NRT) information about SO2 layer height - SO2LH (SO2 generally emitted from a volcanic eruption) and about the contamination of FL.
" }, { "name": "Operational Need", "description": "The OPAS (Operational alert Products for ATM via SWIM) SO2LH service supports the aviation safety control bodies in charge of providing advisory information related to volcano, typically the VAACs, which need situation awareness and dataset to proceed data integration and provide SIGMET, AIRMET and special NOTAM like ASHTAM and SO2TAM. This service also supports other stakeholders relying on the knowledge of the state of the atmosphere and the situation awareness of flights, typically atmospheric dispersion modellers, airlines and aircraft manufacturers. These stakeholders need estimates and forecasts of exposure dose due to SO2 emissions to proceed re-routing in order to avoid significant health effect to passengers / crew and impact on the service life of certain aircraft component (see ICAO ConOps of the 12th Nov. 2018). More details about the Business context can be find in the Final Technical Report (FTR) of the Engage-KTN OPAS project (https://engagektn.com/wp-content/uploads/2020/12/C6-OPAS-final-technical-report.pdf).
" }, { "name": "Service Objective", "description": "The objective of OPAS SO2LH notification service is to provide SO2LH information in NRT. The SO2LH characterises the effective plume height of the SO2 layer related to a volcanic eruption. Note that the SO2 is a proxy for sulphide emissions, which can induce sulphidation inside engines and potentially conduct to an accident caused by engine failure and damage. The SO2LH is also a proxy for the volcanic ash height, which is notoriously difficult to measure. The SO2LH information are currently provided by 3 instruments (TROPOMI and IASI) respectively on board S5P, MetOp-A & MetOp-B POLAR_OPERATIONAL_ENVIRONMENTAL_SATELLITE.
