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 ...
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 ...
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.
GAW Report, 211. Rationalizing nomenclature for UV doses and effects on humans
World Meteorological Organization (WMO) ; Commission Internationale de l'Eclairage (CIE) - WMO, 2014The document reports on current knowledge and experience within the specific field of light and lighting described and is intended to be used by the CIE membership and other interested parties. It should be noted, however, that the status of this document is advisory and not mandatory.
