1. Aerosol remote sensing data centre unit (ACTRIS DC-ARES)


Location: Tito Scalo, Potenza, Italy

Website: http://www.ciao.imaa.cnr.it/, https://scc.imaa.cnr.it

Description: ACTRIS DC-ARES, operated by CNR, is the main responsible for the Single calculus cHain for Aerosol Remote sEnsing (SHARE), the centralized processing suite for the processing of aerosol lidar data. The Single Calculus Chain (SCC) is currently used by some of the EARLINET/ACTRIS stations and it will become mandatory for the retrieval of ACTRIS aerosol profiling data in the operational phase. ACTRIS DC-ARES provides support in setting up SCC for the stations, configuring it, interpreting the results, but also through web forum, documentation and schools. Based on this unique expertise in the aerosol lidar processing, CNR will offer the SCC use to external users for fostering international cooperation and standardization.

Services currently offered: CNR is currently handling the use of SCC for the aerosol processing for some ACTRIS stations. The harmonized and centralized processing is allowing a faster analysis, traceability and faster developments of advanced products. Opening this to external users will foster international cooperation, but also new advancements in different fields. Currently most of the EARLINET stations use the SCC as ordinary tool to analyze raw lidar data. Lidar stations from Latin American Lidar Network (LALINET) are also starting to use SCC to calculate quality-controlled aerosol optical products, and other aerosol lidar observing stations outside ACTRIS have requested access (the last SSC school has involved 6 external users and 16 associated ACTRIS partners. The access to SCC potentially attracts various user communities and countries: new users from outside Europea for improving the aerosol lidar processing (researcher communities), non academic users (e.g., air quality related stakeholders through use in devoted campaigns). The use of the aerosol lidar processing chain could act as baseline for new products development in the private sector for example at prototype system developments, but even as testing for automatic low power lidar and ceilometer processing delivered by producing SMEs.

2. Centre for Aerosol Remote Sensing-Automatic Sun/sky/lunar Photometers (CARS-ASP-FR)

Location:     Lille, France

Web site:    http://www-loa.univ-lille1.fr/photons

Description of the facility: The infrastructure is a TC unit for Aerosol Remote Sensing and in charge of instrumental development, characterization, calibration, data preparation and processing for aerosols retrievals of automatic sun/sky/lunar photometers. The facility contributes to the ground-based standardized automatic sun/sky- photometer network AERONET and complements the US NASA calibration centre. The infrastructure consists of photometry and radiometry calibration platforms for calibration of field instruments and the infrastructure holds a mobile platform simulator that allows to test instruments dedicated to mobile observations.

Services currently offered by the facility: The facility offers calibration, quality control, data processing and training services, and expertise in Aerosol Remote Sensing. CNRS-LOA will offer two types of services: (i) calibration and maintenance for sun/sky/lunar/polar photometers; and (ii) services dedicated to mobile photometry for users willing to upgrade their photometer for mobile (e.g., maritime) observation capabilities. Current CE318T photometer has the capability to perform measurements on mobile platform, as already done (e.g on ships). However, additional components are requested. Aerosols products derived from AERONET Europe activities have shown to be very useful and relevant for supporting lidar aerosol retrievals, joint photometer LiDAR retrievals (LIRIC and GARRLIC), aerosol absorption profiling, night-time AOD and satellite and model validation. The scientific applications of delivered aerosol products / services are widely contributing to research activities in many European and worldwide countries (e.g. China) and 50 % of users are from outside the ACTRIS community. Users come from remote sensing, in-situ, and satellite communities and comprise private companies (for testing and calibration of new, e.g. mobile instruments, or users from climate services (e.g UK MetOffice network).

3. Central Data Processing Systems for FTIR remote sensing data (CDPS-FTIR)

Location:  Brussels, Belgium

Website: https://www.aeronomie.be/

Description of the infrastructure: CDPS-FTIR is a processing system running on HPC infrastructure at BIRA-IASB, as part of the TC unit for Reactive Traces Gases Remote Sensing (CREGARS), for processing remote sensing FTIR level 1 data (spectra) to level 2 data (geophysical products, i.e., total column abundances and in some cases vertical concentration profiles of ACTRIS target reactive gases). It consists of a S/W chain, of which the heart is a spectral inversion code agreed in CREGARS, with a web-based interface for communication with the users, including upload of level1 data, and access to the processing results (level2 data and associated processing logbook). CDPS-FTIR is under development: a beta version is expected in 2020, a fully operational system by 2022.

Services currently offered: Preliminary CDPS-FTIR services have already been set up in the frame of Copernicus Atmosphere Monitoring Service (CAMS) projects. This includes central processing of all in-house measurements and of some collaborating stations. Tests with a preliminary CDPS-FTIR version have enabled users to contribute to the CAMS-84 project and resulted in several research papers. The service is available to all external instrument operators in the worldwide FTIR community; most of them are NDACC-affiliated or candidate NDACC affiliates, but also new FTIR operators outside NDACC may appear, e.g., in developing countries (capacity building). There is a strong willingness to have worldwide consistency of the data to enable research that makes use of the global dataset, e.g., for satellite validation. For users of the ACTRIS CDPS-FTIR service, this consistency is automatically ensured and the data will be much more easily integrated in research studies pertaining to the global scale. CDPS-FTIR is also of interest for new instrumental developments, e.g., by a commercial company, which may require verification of the data that CDPS-FTIR can be provide.

JFJ (3450 m asl), represented in the project by PSI, is the highest research station in Europe that is accessible all year round by rail, and it is the only easily accessible observation point in Europe with adequate infrastructure that is within the free troposphere most of the year. The research station JFJ is therefore of utmost importance for ground-based observations of the free troposphere. As the research observatory is within clouds 40% of the time throughout the year, it provides a unique opportunity for in situ studies of liquid clouds (in summer) and mixed-phase and glaciated clouds (in winter).

Services currently offered by the facility: Users will have access to JFJ measurement platforms to deploy and operate instruments and to data from continuously operating instruments (access to real-time and archived data). The high scientific quality of the atmospheric research is demonstrated by the more than 100 peer-reviewed publications from PSI and EMPA with JFJ data on aerosol and gas phase composition and aerosol-cloud interaction (e.g., Bianchi et al., Science, 352, 1109, 2016; Bukowiecki et al., Aerosol and Air Quality Research, 16, 764, 2016). The JFJ has been massively overbooked by access requests in the past and has high potential to attract new scientific users, as well as users from the private sector. Physical access is offered to a broad variety of atmospheric scientists. Examples of activities comprise closure of organic species in the gas and aerosol phase (links to EUROCHAMP and various CFs), characterization of black carbon, investigation of vertical transport processes, or aerosol-cloud interactions. Testing of newly developed instruments by companies will be supported by cutting-edge complementary instrumentation. The data have high potential to be used by public services such as clear air authorities, and the site has sufficient maturity to provide capacity building e.g. by attracting new facility operators.
