Periodic Reporting for period 2 - AURORA (Advanced Ultraviolet Radiation and Ozone Retrieval for Applications)
Período documentado: 2017-02-01 hasta 2019-07-31
As the most important radiatively active gas in the stratosphere and short-lived climate forcer, oxidizing agent and pollutant in the troposphere, ozone shall be measured from the surface to the mesosphere. This cannot be done by a single instrument, due to limited capability of remote sounding in an assigned spectral region and observation geometry. It could be achieved by merging information of multiple measurements of the same target.
AURORA project demonstrates that the synergistic use of geostationary (GEO) and low Earth orbit (LEO) satellite sensors data in different frequency ranges is a viable strategy for full, vertical ozone profiling.
A novel approach, based on assimilation of GEO and LEO fused products with the application of an innovative algorithm to S-4 and S-5 synthetic data, is adopted to assess quality of the unique ozone vertical profile obtained in a context simulating the operational environment. The vertical distribution is used to calculate tropospheric ozone column and UV surface radiation, thus focusing on lower atmosphere layers.
A technological infrastructure, exploiting virtual machines and cloud data sharing, is created to implement the data processing chain with a geo-database and web-services for data access. The infrastructure represents a best practice that plays a key role in ensuring wider use of Copernicus Sentinel data for academia and industry. It is the basis for a market analysis for pre-market applications and uptake in commercial communities. Strategic dissemination and exploitation is targeted to European level (academia, CAMS, GEOSS, thanks to existing, strategic contacts) and international level (TEMPO and GEMS, in USA and ASIA, who investigate synergy and data exchange).
It is crucial to highlight the fact that the project addressed at the same time:
- the long-term objectve of exploring new research paths to upgrade their products to the operational level of Copernicus services like CAMS and C3S;
. the shorter term goal of making available a novel approach and the necessary technological infrastructure toaplly that to the first real data from the atmospheric Sentinels.
Importance of the project content to our daily lives: project outcomes are relevant to citizens’ everyday lives, to competitiveness and to solving societal challenges. AURORA exploited the positive impact of satellite data in improving quality of life, especially though sectors such as the chemical, pharmaceutical and the public health sector (application) and the importance of satellite data themselves (research).
Looking at the general impact, the atmospheric Sentinels are expected to deliver a large amount of data with unprecedented temporal and spatial resolution and data continuity.
This allows for better assessment of air quality, which helps to make more effective policies and evaluate implemented policies with improved measurement methods, thus having direct positive effects on the living environment and the health of millions of people.
The availability of this large quantity of data will represent an important opportunity for societal relevant commercial services and scientific studies and for increase of knowledge on the atmosphere. Moreover the large improvement in the quality of the data provides a unique opportunity for the development of new products addressed to market.
- The generation of atmospheric scenarios necessary for the simulation of atmospheric Sentinels data products;
- The collection of instruments characteristics and observation geometry data
- The specification of the set of parameters requested for the simulation of data from the LEO and GEO sounders in the Ultraviolet, Visible and Thermal Infrared regions;
- The assessment of specifications and requirements for data fusion and data assimilation and forecast, for the AURORA products related to Tropospheric Ozone and UV surface radiation;
- The definition of the Requirements for the AURORA Technological Infrastructure (i.e. the Geo-database, the specific tools for data interface, the web services tools, the data visualization tools, and the Prototype Data Processo for the integration of the different components);
- The definition of the Requirements for Exploitation Activities;
- The definition of the Requirements for Management Procedures.
Progresses beyond the expections were also achieved by the application-driven activities, which represented a fundamental part of the project work plan and turned out to provide an output products immediately raised to the level of commercial applications rather than pre-market versions of services mostly conceived for demonstration purposes.
These results were made possible also thank to the effort devoted and accomplished results in terms of key enabling technologies.
Amajor proof of potential and actual impact of the results obtained by the project might be recognized in the creation of two new SMEs out of the set of industrial partners joining the Consortium at the beginning of the project. Both of them are active on the market in the health sector, which is among themost promising for future development of businnes cases linked to exploitation of advanced quality data from new generation spaemissions.
