Foreword<\/strong><\/h2>\n\n\n\n

Dear EuBrewNet contributor \u2013 in our second newsletter we tell you how your data is being used by more and more researchers and how it is becoming more visible through cooperation with NDACC and WOUDC. Along with other technical updates, including the new version 2 algorithm, EuBrewNet also now offers more data products and file formats for data exchange with other networks.<\/p>\n\n\n\n

EuBrewNet observations linked in the WOUDC<\/strong><\/h2>\n\n\n\n

EuBrewNet total ozone observations are now accessible from WOUDC. Users can search EuBrewNet from the Data Search \/ Download page<\/a>, and download resulting data directly from EuBrewNet. Note that downloading data from EuBrewNet requires authentication. <\/p>\n\n\n\n

EuBrewNet-NDACC cooperative Agreement <\/strong><\/h2>\n\n\n\n

During the last NDACC meeting  a cooperative agreement between two networks was presented, this agreement mutually recognized both networks reinforcing  the cooperation between two networks and maintained his own data policy.The stations\/PI that participate on both networks with the same measurements continue to submit  the observation to both networks.  The agreement now in discussion for both networks can be read here.<\/p>\n\n\n\n

The Iza\u00f1a (Spain)  and Uccle (Belgium)  stations which take part in both networks are developing the real time submission of the Brewer V2 total ozone to the NDACC using EuBrewNet.<\/p>\n\n\n\n

ET-ACQM – A new Expert Team on Atmospheric Composition Measurement Quality <\/strong><\/h2>\n\n\n\n

Within the reorganization of the WMO a new structure was created by so called Expert Teams. The Expert Teams within GAW are now responsible for the advances in the research infrastructure in collaboration with SAG and the Infrastructure commision.  This ET-ACQM will deal with the QA\/QC of GAW measurements, and in the case of the Total Ozone the new group will combine activities that were part of the O3-SAG  and  SC-MINT (Standing Committee on Measurement, Instrumentation and Traceability) the  former CIMO.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

One of the objectives of these ET is to guarantee the quality of every GAW stored measurement: <\/p>\n\n\n\n

  1. The measurement value is obtained following the SOP.<\/li>
  2. Overall Uncertainty is reported and the traceability uncertainty chain documented<\/li>
  3. Flag Code providing the state of processing \/validation, reliability  and representativeness.<\/li>
  4. Metadata sufficient for data reprocessing from raw data. <\/li><\/ol>\n\n\n\n

    Is clear that the Brewer total ozone observations has a lot of work to do starting with an unfinished SOP\u2019s, the lack of uncertainty budget, traceability documentation, and in the case of WOUDC the impossibility to reprocess Brewer data starting from raw observations through a lack of metadata.   <\/p>\n\n\n\n

    Associated to this Expert Team, a  Total Column Ozone (including Umkehr) Task Force has been created with two co-chairs: Irina Petropavlovsky (Dobson) and Alberto Redondas  with the following key topics to address:<\/p>\n\n\n\n
