COST ACTION ES1207 EUROPEAN BREWER NETWORK (EUBREWNET)

EMRP TRACEABILITY FOR ATMOSPHERIC TOTAL COLUMN OZONE (ATMOZ)

15th BIENNIAL WMO-GAW BREWER USERS GROUP MEETING

IPMA, Ponta Delgada, Sao Miguel, Azores, Portugal 17th to 20th May 2016

 

The RBCC-E (Regional Brewer Calibration Center for Europe), managed by the CIAI (Izaña Atmospheric Research Center) of the State Meteorological Agency of Spain (AEMET) and the “Intelligent Sensor” Research Group of the University of La Laguna (ULL), has participated in the “Brewer Ozone Spectrophotometer/Metrology open workshop” organized by EUBREWNET (COST Action ES1207),  ATMOZ (Traceability for atmospheric total column ozone, European Metrology Research Programme ENV59) y WMO-GAW (World Meteorological Organization – Global Atmosphere Watch), which was held in Ponta Delgada (Portugal) from 17th to 20th May 2016. More than 50 researchers from 13 countries of the European Union, the United States and Canada, participated in this meeting.

The Brewer Ozone Spectrophotometer is widely used throughout the world for ground based total ozone column (TOC) measurements and can also provide solar spectral UV, Aerosol Optical Depth (AOD), NO2 and SO2 data, plus ozone vertical profiles from Umkehr measurements. The EUBREWNET COST action is an european project which aims to establish a coherent network of Brewer Spectrophotometer monitoring stations throughout Europe and to collaborate with other regional networks in order to harmonise operations and develop approaches, practices and protocols to achieve consistency in quality control, quality assurance and coordinated operations.

The main objective of the European Metrology Research Programme (EMRP) funded project ATMOZ is to provide traceable total column ozone measurements from Dobson, Brewer and DOAS type spectroradiometers, including a comprehensive uncertainty budget.

The workshop focused on the operational, scientific and technical issues of the Brewer instrument and its role in the global ozone, aerosol and UV monitoring networks, as well as the development of new instruments and characterisation methods. The workshop also provided an opportunity for formal and informal exchange of information by those involved in the use of Brewer UV and Ozone spectrophotometers, as well as others who have a general interest in atmospheric spectroscopy in the visible and ultraviolet.

AEMET and ULL have an outstanding participation in both EUBREWNET network, managing the project database and ozone calibration center, as in the ATMOZ project. This work is shown in the contributions of the group to the Workshop:
