Foreword<\/h1>\n\n\n\n

Dear EUBREWNET contributor \u2013 did you know that your data is now considered part of a fiducial reference network and is used for TROPOMI Sentinel 5P ozone validation? In this our first newsletter you can find out how EUBREWNET, which you all played a part in creating, has matured and developed and is working to make sure that your data is recognised as having the highest quality and accredited to you, the producer.
<\/p>\n\n\n\n

Please read on to find out more, always remember that any feedback will be welcome and appreciated, and please send us details of your EUBREWNET related publications.<\/p>\n\n\n\n

Network status and new stations.<\/h1>\n\n\n\n

Six new stations have joined EUBREWNET in 2019: Nairobi (Kenya), Athens (Greece), Buenos Aires (Argentina), Petaling Jaya (Malaysia), New Delhi (India), and Princess Elizabeth (Antarctica). The number of stations taking part in the network is now 57. With regard to users, we have created 21 new accounts, which raises the total number of registered users to almost 120.<\/p>\n\n\n\n

Governance<\/h1>\n\n\n\n

Since the end of 2018, support to EUBREWNET has been provided by AEMET. The conduct of activities carried out are overseen by a governance committee within the WMO SAG Ozone, which includes J. Rimmer (University of Manchester, UK), A. Redondas (Izan\u0303a Atmospheric Research Centre, AEMET, Spain), T. Kralidis (WOUDC), M. Tully (O3 SAG Chair), and C. Sinclair (UV SAG Chair). Scientific input is provided by EUBREWNET\u2019s Management Committee, consisting of J. Rimmer (University of Manchester, UK), A. Redondas (Izan\u0303a Atmospheric Research Centre, AEMET, Spain), A.F. Bais (Aristotle University of Thessaloniki, Greece), J. Gro\u0308bner (Physikalisch – Meteorologisches Observatorium Davos\/World Radiation Center, Switzerland), T. Karppinen (Finnish Meteorological Institute, Arctic Research Center, Finland), and V. De Bock (Royal Meteorological Institute of Belgium, Belgium). <\/p>\n\n\n\n

EUBREWNET as Fiducial Reference Network<\/h1>\n\n\n\n

During the last meeting of the Ozone Scientific Advisory Group of WMO, the Maturity Index Matrix  for the EUBREWENET Network was presented.<\/a> The maturity matrix has been developed within the H2020 GAIA-CLIM (www.gaia-clim.eu) project to different data products and networks, see Thorne et al. (2017)<\/a>. The idea behind this is to provide a framework and tool to semi-objectively classify measurement capabilities. The idea is also to identify and characterise mature data sets and include them in the Virtual Observatory developed within GAIA-CLIM to be used for satellite to non-satellite data comparisons. The EUBREWNET Maturity Index Matrix was evaluated by  Karin Kreher with quite good results, so that Eubrewnet can be considered as a Fiducial Reference Network for total ozone measurements.<\/p>\n\n\n\n

TROPOMI S5P total ozone column global validation within the VALTOZ project<\/h1>\n\n\n\n

The observations of individual Brewer spectrophotometers of EUBREWNET have been used for the validation of the TROPOMI Sentinel 5P ozone measurements (Garane et al., 2019<\/a>). This was the first time EUBREWNET data was used for satellite validation. A similar future comparison is planned for NASA EPIC ozone observations. Only the high frequency EUBREWNET observations have sufficient time resolution to operationally validate the diurnal variation as provided by TROPOMI and EPIC.<\/p>\n\n\n\n

EUBREWNET ozone observations in Copernicus Climate Services<\/h1>\n\n\n\n

EUBREWNET was invited to the annual meeting of the \u201cAccess to observations from baseline and reference networks\u201d (C3S_311a_Lot3_CNR<\/a>) in July 2019. At this meeting Alberto Redondas gave a presentation of the network<\/a>. In this project, WMO participates as a contractor and supplies the ozone data from WOUDC.  The project wants to add EUBREWNET daily Level 2 data, in principle the same that is linked to from eubrewnet on WOUDC. Similar to the observations stored in WOUDC, the data in Eubrewnet are open and free and we don’t see any problem to submit these data by default. The Services show interest to have an error budget estimation of these observations and the ESA representative at the meeting is open to financially support this new development in EUBREWNET.<\/p>\n\n\n\n

DOI linked to EUBREWNET datasets<\/h1>\n\n\n\n

EUBREWNET observations are beginning to be used for satellite validation and Climate Services, for example ESA Sentinel 5 (see Garane et al., 2019<\/a>), EPIC satellite validation is on discussion with NASA  and Climate Services  like  Copernicus CS3. <\/p>\n\n\n\n

In the case of the total ozone deposited at WOUDC the data are open and free and most of the institutions collaborating with EUBREWNET follow the open data policy. The EUBREWNET data policy is available on the website<\/a>. In short, co-authorship should be extended whenever the use of such data plays a significant role in published work.  Further, the user should contact the associated measurement PI to ascertain whether there are any data revisions in progress, and to verify that the intended use of the data is scientifically appropriate.  However, experience has shown that EUBREWNET data has been used in publications without proper reference or acknowledgments, although they constitute an important part of these publications. <\/p>\n\n\n\n

Using a DOI for the \nEUBREWNET data is the best solution to properly reference the data even \nwhen it is ingested on wider systems like Copernicus.<\/p>\n\n\n\n

Granularity: One DOI for each data product from each station DOIs will be allocated for: data products and level.

E.g. \u201cdoi: 10.1234\/XXXNNo3v10l15\u201d  \u2192

10.1234: assigned by AEMET
XXXNNN : Station:Brewer

p1-6: processor version

– The metadata will follow the ESA\/AVDC guidelines (http:\/\/evdc.esa.int\/documentation\/doi-docs\/), with the exception of the rights (copyright info) all the information is already on the database.
– The DOI will not change when the data are processed and updated.<\/p><\/blockquote>\n\n\n\n

Staff reinforcement<\/h1>\n\n\n\n

We are pleased to announce that AEMET, through TRAGSATEC (https:\/\/www.tragsa.es<\/a>), is supporting EUBREWNET since February 2019 with two new staff positions. Alberto Berj\u00f3n and Javier L\u00f3pez-Solano have joined the development team of the EUBREWNET project to work on the online application and server maintenance, assistance to users, and support to the development of new functions in EUBREWNET. For any questions or suggestions, you can contact the development team at the email eubrewnet@aemet.es<\/a>.<\/p>\n\n\n\n

In the future, we will be able to give support to new stations, and finish some pending issues such as:<\/p>\n\n\n\n
