THE XII INTERCOMPARISON CAMPAIGN OF THE REGIONAL BREWER CALIBRATION CENTER-EUROPE

\nCOST ACTION ES1207 EUBREWNET CAMPAIGN
\nATMOZ (Traceability of Atmospheric Total Ozone) Field demonstration campaign<\/p>\n

Go to top<\/a><\/div>\nDear Brewer spectrophotometer user community,<\/p>\n

This is an invitation to Brewer experts and\/or operators to participate in the COST ACTION ES1207 European Brewer Network (EUBREWNET) campaign\/ XII Regional Brewer Calibration Center for Europe (RBCC-E) intercomparison that will be held at El Arenosillo Atmospheric Sounding Station of the \u201cInstituto Nacional de T\u00e9cnica Aeroespacial\u201d (INTA) during the period 29 of May to 7 of June, 2017.<\/p>\n

This campaign is part of the EUBREWNET ES1207 COST Action and is organized in collaboration with the \u201cArea of Instrumentation and Atmospheric Research Area\u201d of INTA, with the support of the Global Atmospheric Watch (GAW) program of the World Meteorological Organization (WMO). This campaign will be used as demonstration campaign of the calibration methodologies and error assessment developed by the EMRP ATMOZ project (Traceability of Atmospheric Total Ozone).
\nIn November 2003, and within the GAW\/WMO program, the Regional Brewer Calibration Centre for RA-VI Region (Europe) (RBCC-E) was established by Iza\u00f1a Atmospheric Research Centre (I-ARC) at Iza\u00f1a Observatory (IZO, Canary Islands), managed by the \u201cAgencia Estatal de Meteorolog\u00eda\u201d (AEMET, Spain). Technical and organization information of the RBCC-E can be obtained at http:\/\/rbcce.aemet.es.<\/p>\n

At present the RBCC-E maintains a triad of reference instruments. The Regional Primary Reference Spectrophotometer (B157) and the Regional Travelling Reference Spectrophotometer (B185) are part of the triad. Each spectrophotometer is calibrated independently with the standard Langley method at IZO. Until now the IZO Triad has been linked to the EC-MSC Word Reference Triad by yearly calibrations towards the International Ozone Services (IOS) travelling reference Brewer 017. Recently however as a result of doubts about the support of the world triad by (EC-MSC), the WMO SAG authorized (at the meeting of 2011) that the RBCC-E transfers its own calibration based on Langley at Iza\u00f1a Station.<\/p>\n

The traveling references B017 operated by IOS experts and the B158 operated by Kipp & Zonen will participate to this intercomparison. That will allow participants to order Kipp & Zonen or IOS or for technical servicing on their instruments during the campaign.<\/p>\n

The action focuses on the calibration of Brewer spectrophotometers from Europe and North Africa. The RBCC-E will provide ozone and Aerosol Optical Depth (AOD) calibration against the RBCC-E reference, whereas the QASUME unit of the Physikalisch-Meteorologisches Observatorium Davos \/ World Radiation Center (PMOD \/WRC) will provide a global UV reference spectrum for the ultraviolet measurements.<\/p>\n

Schedule<\/h2>\n

The campaign is scheduled in four main phases:<\/p>\n

    \n
  1. Initial calibration to assess the current calibration of the instruments.<\/li>\n
  2. Servicing, adjustments and maintenance works characterization test of the instruments.<\/li>\n
  3. Final calibration. In this phase the \u2018UV\u2019 calibrations against the QASUME.<\/li>\n
  4. Specific measurements for Brewer.<\/li>\n<\/ol>\n
