GAW Report, 224. Ninth Intercomparison Campaign of the Regional Brewer Calibration Center Europe (RBCC-E)
This ninth intercomparison campaign was a joint exercise of the Regional Brewer Calibration Center for Europe (RBCC-E) and the Arosa Lichtklimatisches Observatorium (LKO) of MeteoSwiss during the period 14-26 July 2014. Six Brewers managed by 11 experts from four countries participated in the campaign (Table 1). The Brewer instruments were compared with the RBCC-E travelling reference Brewer #185 for ozone. The RBCC-E transferred during this intercomparison its own absolute ozone calibration obtained by the Langley method at the Izaña Observatory (IZO). The calibration of the reference instrum ...

The RBCC-E transferred during this intercomparison its own absolute ozone calibration obtained by the Langley method at the Izaña Observatory (IZO). The calibration of the reference instrument, as well as the link to the world triad, is discussed in Section 2.1. All the participating instruments were provided with a provisional calibration at the end of the campaign, which can be considered final calibration constants for most of them. The individual calibration reports are also available online. A calibration history was introduced for those instruments present at previous campaigns, allowing an easy recalculation of the past ozone data.

GAW Report, 223. Eighth Intercomparison Campaign of the Regional Brewer Calibration Center for Europe (RBCC-E)
The eighth Regional Brewer Calibration Center for Europe (RBCC-E) intercomparison was held at El Arenosillo Atmospheric Sounding Station of the Instituto Nacional de Técnica Aeroespacial (INTA) during the period 10-20 June 2013. This campaign was organized in collaboration with the Area of Instrumentation and Atmospheric Research of INTA, with the support of the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO) and a CEOS CALVAL project of the European Space Agency (ESA). A total number of 18 Brewer spectrophotometers from eight countries participated in th ...

Published by: WMO ; 2015The eighth Regional Brewer Calibration Center for Europe (RBCC-E) intercomparison was held at El Arenosillo Atmospheric Sounding Station of the Instituto Nacional de Técnica Aeroespacial (INTA) during the period 10-20 June 2013. This campaign was organized in collaboration with the Area of Instrumentation and Atmospheric Research of INTA, with the support of the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO) and a CEOS CALVAL project of the European Space Agency (ESA). A total number of 18 Brewer spectrophotometers from eight countries participated in the intercomparison. These campaigns, with a large number of participant instruments, provide an overview of the current state of ozone measurements being made by the European Brewer network. The instruments were compared with the RBCC-E standard Brewer#183 for ozone and with the European UV reference from the World Radiation Center (QASUME unit) for UV. For this report we used our own calibration constants obtained by Langley plots at IZO. Apart from the RBCC-E standards, two additional reference instruments were present at the campaign: the single-monochromator Brewer #017 (IOS, EC) and the double-monochromator Brewer #158 (K&Z).

GAW Report, 214. Report of the GAW 2013 Symposium and the Fourth Session of the CAS JSC OPAG-EPAC
The meeting reviewed current WMO data quality objectives and observation scales, covering such topics as carbon dioxide and other greenhouse gases, stable isotopes, radiocarbon in greenhouse gas measurements, calibration, quality control, data management and archiving. The workshop also discussed new and emerging technologies, including measurements of greenhouse gases with high-precision spectroscopic methods. The group made several recommendations on the WMO data quality objectives, as well as on the development of the GAW Programme infrastructure. These recommendations are summarized in the ...

GAW Report, 212. Standard Operating Procedures (SOPs) for Spectral Instruments Measuring Spectral Solar Ultraviolet Irradiance
This document outlines such operating procedures for spectral UV measurements and is intended for use by station operators. As it does not present the details of instrument characterization and calibration, the guide should be used in conjunction with GAW Reports No. 125 [WMO, 2001], No. 126 [WMO, 1998], No. 146 [WMO, 2003], and No. 191 [WMO, 2010] providing more detail and background information.
