CEN-Workshop at WCCAP/TROPOS

World Calibration Centre for Aerosol Physics (WCCAP)
The WCCAP was founded in 2002 to serve as a competence center for in-situ physical and optical aerosol measurements as part of the world-wide GAW-program of the WMO. This WCCAP is world-wide unique for the quality assurance of physical and optical in-situ aerosol measurements and station audits to improve infrastructures.
European Reference Laboratory for Air Pollution (ERLAP)
ERLAP was founded in 1994 to serve as a calibration facility for measurements of particulate matter and gaseous air pollutants in Europe. Inter-laboratory comparisons have been organized yearly or more for 2 decades. As a service of the European Commission, ERLAP provides support independently of national and private interests, which makes it unique in Europe.
Aerosol Chemical Monitor Calibration Center (ACMCC)
The ACMCC is managed by a consortium of French laboratories, including CNRS (LSCE and LaMP) and INERIS, and is mainly based at LSCE, located south of the Paris region. As part of the quality control procedures, the ACMCC provides a large set of independent co-located on-line/off-line aerosol measurements for chemical, physical and optical parameters. It offers innovation opportunities through the exchange of information between manufacturers and users, the optimization of technological solutions, and the evaluation of new online aerosol chemical analyzers.
Prague Aerosol Calibration Centre (PACC)
The PACC was founded in 2020 as part of ACTRIS Topical Centre for Aerosol In-Situ observations (CAIS/ECAC). It serves for calibration and quality assurance of physical in-situ aerosol measurements and station audits for ACTRIS and for external users. (operational 2021)
Cluster Calibration Center (CCC)
CCC was founded in 2018 to serve as a calibration facility for sub 10 nm aerosol, cluster and ion measurements. It provides instrument-specific calibration services and training. (operational 2021)
Organic Tracers and Aerosol Constituents Calibration Center (OGTAC-CC)
The Atmospheric Chemistry Department of TROPOS hosts the Organic Tracers and Aerosol Constituents - Calibration Centre (OGTAC-CC), which is the first calibration center for these class of compounds worldwide, providing a strong benefit to the aerosol community, as it harmonizes approaches for the chemical analysis of organic particulate constituents.
Elemental Mass Calibration Centre (EMC2)
The EMC2 unit will be hosted in the INFN LABEC laboratory which is devoted to the analysis of the elemental composition of aerosols, environmental samples and cultural heritage by means of analytical nuclear techniques, such as ion beam analysis, besides other field of applications, for instance material science and forensics, and radiocarbon dating with accelerator mass spectrometry. The LABEC laboratory was born in 2003 with the installation of a 3 MV Tandetron particle accelerator and stems from more than thirty years of experience of the research group members with accelerator-related analytical techniques.

CAIS-ECAC
Published by WCCAP in Workshop · Friday 07 May 2021 ·  3:00
Agenda
 
Day 1: Pre-status
 
·         set-up of the instruments
·         check data logging for pulse output (BNC) and internal output with corrections
·         particle free runs to check for leaks
·         check plateau by 40 nm
·         Check Dp50 by 10nm – possibly calibration for fine tuning of the CPCs
·         Check Dp50 by 7nm
·         CPC efficiency curve No.1 (if there are timely constrains this will be done on Wednesday)
·         Overnight CPC intercomparison with lab air
 
Day 2: CPC Workshop
 
·         CPC efficiency curve No.2: check whether curve No.1 is reproduceable
·         Linearity 2000 to 60000 #/cm3
·         Overnight CPC intercomparison with ambient air
 
Day 3: Second intercomparison
 
·         Response time
·         Discussion of the results
·         Possibly additional measurements and repetitions of calibrations
 
Day 4: Final Intercomparison
 
·         Set-up for the long-time measurements (one week until 08.06.21); ambient aerosol
·         Departure of the guests on Friday
  
Additional Information
 
1.  Some important rules due the COVID-19 situation
 
Please show the result of a quick test, not older than 24h, at your arrival on 25th May.

On Wednesday and Friday, you will get tests from WCCAP/TROPOS. Please use them before the workshop. Please use an FFP2 mask during the whole workshop. Due to the situation (COVID-19) and the usage of our interim laboratory there is limited space. So only one person per institute/company is allowed to take part in the workshop.
  
2.  For any questions and remarks regarding your instruments, please contact the corresponding workshop head, Kay Weinhold: weinhold@tropos.de
 
3.  Shipping of Instruments to TROPOS
 
The instruments have to be at TROPOS until 25.Mai 2021, 9 am.
 
If you have to send instruments, please do so that they arrive at TROPOS latest until Friday, 21st May. This is because Monday, 24th May is holiday in Germany.
 
Please coordinate the shipping with us. The shipping address is:
