RESEARCH PERFORMING ORGANISATIONS
The eight Central Facilities coordinates ACTRIS operation at European level and consists of six Topical Centres, the Data Centre and the Head Office. Each Central Facility consists of several Units hosted by a responsible ACTRIS Research Performing Organisation (RPO) of an ACTRIS member country. CFs participate in ACTRIS governance and management and provide services to the users accordingly to the user access policy as well as operation support to the National FacilitiesREAD MORE
ACTRIS Data Centre (DC) is responsible for handling the ACTRIS data. The primary role of ACTRIS DC is to compile, archive, and provide access to well documented and traceable ACTRIS measurement data and data products, including digital tools for visualisations, data analysis, and research. As a tool for science, the highest priority for ACTRIS DC is to maintain and increase the availability of ACTRIS data and data products relevant to climate and air quality research for all interested users. All primary measurement data and produced data products are made available to the users via the ACTRIS data portal. ACTRIS DC provides scientists and other user groups with free and open access to all measurements, both quality-assured data and near-real-time data, archived in interoperable topical data repositories handling diverse types of data.READ MORE
The Head Office is the central hub of ACTRIS, coordinating ACTRIS operations and enabling ACTRIS services. The Head Office supports the work of the General Assembly and the advisory bodies and committees of the ACTRIS ERIC.
The HO coordinates the RI at the European level, in close cooperation with the national ACTRIS consortia, the NFs, and the other CFs. ACTRIS Head Office (HO) is in charge of the strategic development and planning of ACTRIS
services for users to solve important scientific questions and in promoting technology
development and innovations.
HO also manages and oversees future cooperation with RIs from other domains. HO coordinates and promotes ACTRIS services, handles internal and external communication, operates the legal entity, and ensure the strategic development and sustainability of ACTRIS. The HO coordinates the RI at the European level, in close cooperation with the national ACTRIS consortia, the NFs, and the other CFs.
The European Center for Aerosol Calibration and Characterization (ECAC) aims at acting as the ACTRIS Centre for Aerosol In Situ measurements (CAIS), whose mission is to offer operational
support to ACTRIS National Facilities (NFs) for the physical and/or chemical in situ characterisation of atmospheric aerosol particles as well as for particle sampling and subsequent laboratory analysis of these
particles. ECAC will also offer measurement and data tools related to aerosol in situ measurements.
Additionally, ECAC will offer specialised services, CAIS-related variables, to ACTRIS users of various types: academia, business, industry, and public services.
ECAC is divided thematically into two branches – one dealing with physical aerosol properties and the other one with the chemical composition of aerosol particles.
The mission of the Centre for Aerosol Remote Sensing (CARS) is to offer operational support to ACTRIS National Facilities
operating aerosol remote sensing instrumentation: aerosol high-power aerosol lidars, automatic low power lidars and ceilometers, and automatic sun/sky/polarised/lunar photometer.
Additionally, the Centre for Aerosol Remote Sensing offers specialised services for the above instruments and related ACTRIS variables, to ACTRIS users of various types: academia, business, industry and public services.
The key mission of the Centre for Cloud In Situ Measurements (CIS) is to offer operational support to ACTRIS National Facilities (NFs) operating instrumentation for continuous
long-term measurements of cloud occurrence, cloud water content, and cloud droplet effective diameter at observational platforms, or for episodic measurements of cloud particle size distributions,
chemical cloud water composition, and ice nucleating particles during dedicated laboratory and field campaigns.
While the main activities focus on the ACTRIS community, specialised services are offered to users from academia, business, industry, and public services.
The aim of CIS is to develop and adapt its procedures and performance to future needs continuously responding to new research and development projects, with a focus on the operation of existing instruments and methods, and the development and implementation of improved and new methods in cooperation with the NFs and other Topical Centres (TCs).
The mission of the Centre for Cloud Remote Sensing (CCRES) is to offer operational support to ACTRIS National Facilities operating cloud remote sensing instrumentation, namely to Doppler Cloud Radars (e.g. Ka, W-band), microwave radiometers for temperature and humidity profiling, and Doppler lidars for wind profiling. CCRES will also provide support for automatic low power lidars and ceilometers used for cloud profiling purposes.READ MORE
The key mission of CiGas is to offer current state-of-the-art operational support to ACTRIS National Facilities (NFs), operational and exploratory platforms, which are operating instrumentation for continuous long-term measurements
of volatile organic compounds (VOCs), condensable vapours and nitrogen oxides (NOx) in the atmosphere. That includes activities to guide research and service development
in the field of reactive trace gases and to develop towards future user needs, utilising innovative methodologies.
The operational support to ACTRIS NFs is supplemented by tailored services for users from the Global Atmospheric Watch Network (GAW) and other atmospheric observation networks, academia, business, industry, and public services depending on the respective resources.
The mission of the Centre for Reactive Trace Gases Remote Sensing (CREGARS) is to offer operational support to ACTRIS National Facilities operating FTIR (Fourier-Transform Infrared),
UVVIS (UV_visible) spectrometers or Ozone Dial (Differential Absorption) LIDARS.
Additionally, CREGARS should offer specialised services similar to the support offered operationally to ACTRIS beneficiaries, for the above instruments and related ACTRIS variables, to ACTRIS users of various types (academia, research organisations, business, industry and public services) that are part of the global Reactive Trace Gases Remote Sensing (RTGRS) community.
The National Facilities (NFs) comprise Observational and Exploratory Platforms, both within Europe and at selected global sites.
Exploratory Platforms and selected Observational Platforms provide users with physical access to state-of-the-art, well-characterised and versatile facilities.
ACTRIS NFs support long-term observation and operations related to atmospheric aerosol, clouds and reactive trace gases, following measurement methodologies and procedures defined by ACTRIS TCs.
ACTRIS Observational Platforms are fixed ground-based stations delivering long-term high-quality data on a regular schedule and common operation standards by applying state- of-the-art remote-sensing and in situ measurement techniques.READ MORE
ACTRIS Exploratory Platforms are atmospheric simulation chambers, laboratory platforms and mobile platforms that perform dedicated experiments and contribute data on atmospheric constituents.READ MORE
