Has been working in the field of atmospheric sciences and climatology for the past 45 years. His research positions include Postdoc, Advanced Study Programme at the National Center for Atmospheric Research, USA; the National Hellenic Research Foundation; the National Oceanic and Atmospheric Administration, USA; the University of Oslo; the Laboratories of Atmospheric Physics, Universities of Athens and Thessaloniki, Greece; the National Observatory, Athens; the Academy of Athens. Participated in more than 90 research projects (60 of which from EU, WMO and the US). Has participated in prestigious international research committees and commissions e.g. Member of EU Advisory Groups for DGXII; Member of the WMO AD HOC Scientific Steering Committee on UV Monitoring and the WMO AD HOC Scientific Steering Committee on Ozone (Ozone-SAG); Member of the ENRICH Council of the European Union; Member of the WMO Executive Council Panel of Experts/CAS Working Group on Environmental Pollution and Atmospheric Chemistry; Member of EU (EC) Stratospheric Science Panel which organized all European Arctic stratospheric ozone experiments, among other large projects. Has served as Secretary and President of the International Ozone Commission (IO3C) and elected Honorary Member of IO3C in 2016.
Christos Zerefos became known in the 70s for his studies on the long- and short-term variability of ozone. The solar activity effects in the lower stratosphere, e.g. his paper with Paul Crutzen (JGR, 1975) was one of the first studies to model the physics of solar activity-stratosphere relations. With Harry van Loon they first observed the El Nino signals in the lower stratosphere (Mon. Weather Rev., 1982) and in the columnar ozone (JGR, 1992). His early papers on long term trends in stratospheric temperatures and total ozone include one of his most important papers with Stolarski et al. (Science, 1992), which boosted the scientific basis for the Montreal Protocol, which led out to the phase out of halocarbons. This work has been updated in 2014 (Zerefos et al., ACP, 2014).
His papers on the inverse relationship between ozone and UV-B, provided for the first time evidence that UV-B had significant positive trends. “A note on the recent increase of solar UV-B over northern mid latitudes”, GRL, 1995, “Optical properties of tropospheric aerosols …, Appl. Optics, 1997, "Spectral measurements of solar UVB radiation and its relations to total ozone, SO2, and clouds", JGR, 1993 as well as his papers on record low total ozone anomalies and the effects of volcanic eruptions (e.g. with Bojkov “Record low total ozone during northern winters of 1992 and 1993", GRL 1993). In the 80s Zerefos pioneered in establishing regular well calibrated observations of UV spectral irradiance worldwide. In the 90s has pioneered in the establishment of the European UV-B observing network which started from his initiative with Anne Webb and Alkis Bais (Zerefos et al, GRL, 1997). His thorough research with the Brewer spectroradiometer led to its establishment as a model instrument to measure columnar ozone, SO2 and UV spectral irradiances (Zerefos et al., J. Photoch. & Photobio., 1995; Zerefos et al., GRL, 1997) and with Bais and McElroy (GRL, 1996; Appl. Optics, 1998). His papers on the inverse relationship between ozone and UV-B, provided for the first-time evidence that clear sky UV-B had significant positive trends (GRL, 1995; Appl. Optics, 1997) as well as his papers on record low total ozone anomalies and the effects of volcanic eruptions (e.g. with Bojkov, GRL 1993).
In the 90s Zerefos has organized large EU-funded campaigns to study the processes of ozone-aerosol-radiation and photochemical interactions in the Mediterranean (PAUR Campaigns I, II and MEDCAPHOT Campaign with Ziomas) (Zerefos et al., JGR, 1997; Balis et al., JGR, 1997; Zanis et al., JGR, 1997; Hofzumahaus et al., JGR, 1997; Kourtidis et al., JGR, 1997; Kouvarakis et al., JGR, 1997). In the 2000s he participated in the MATCH Campaigns joining the European group led by Rex, Schultz and others which studied ozone loss rates inside and outside of the polar vortex (JGR, 2001; GRL, 2000, 2006). On another collaborative project with Stohl et al., studied and reviewed mechanisms of stratosphere-troposphere exchange (JGR, 2003) and with Harris he revisited trends in stratospheric and free tropospheric ozone (JGR, 1997). Notable is his research in the variability of UV-B (GRL, 1997; GRL, 1998) and its natural fluctuations from volcanic signals in the ozone layer (JGR, 1994). He has experimentally discovered the effects in the stratosphere of the solar eclipses of 1999 (JGR, 2000) and 2006 (ACP, 2007, 2008) presenting evidence of atmospheric gravity waves following the supersonic transport of the moon’s shadow in the ozone layer.
Has served as review Editor of Chapter 5 of the IPCC Aviation Report (1999) and as Reviewer of the IPCC Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (2013). The paper with Sausen “Aviation radiative forcing in 2000: An update on IPCC” (Met. Z., 2005) as well as his papers in JGR, 1997, 2005; ACP, 2003, 2012; Tellus B, 2009 in which the solar radiation ozone climate interaction and trends are studied, are included among his highly cited papers.
His pioneering work on the use of red-to-green ratios to detect aerosol in paintings by great masters (Zerefos et al, 2007, 2014) is being widely discussed in scientific and mass media globally. Other papers include climatological-paleoclimatological studies with Luterbacher et al. (Climate Change, 2010; Environ. Res. Lett., 2016). More recently, his papers on Copernicus services and products have been widely quoted (Inness et al., ACP, 2013, 2015; Wagner, ACP, 2015; Eskes, Geosci. Model Dev., 2015) and together with several of the previously mentioned papers have been selected as hot spots by the editors of prestigious scientific journals. His bibliometric indices are: 269 publications with 8.634 citations (without self-citations), h-index 56 (from Web of Knowledge, March 2022) and a total of 520 publications with 14.537 citations, h-index 67 (from Google Scholar, March 2022).
In the past 45 years Zerefos has established a high-level long-lasting collaboration with WMO and the DG Research and Innovation of EU. He has co-organized with WMO the historic 1984 Quadrennial Ozone Symposium where the ozone “hole” has first been presented by Chubachi and established by Farman et al. (1985) as well as the adoption of Bass and Paur ozone absorption coefficients, which has been globally used by the global ozone observing network. Also, in collaboration with WMO, he organized the 2004 Quadrennial Ozone Symposium and other international ozone-climate symposia in 1994, 1995, 1998, 1999. On the occasion of the 20th anniversary of the Montreal Protocol has co-organized with WMO a Symposium in 2007 at Athens, Greece. Subsequently has co-organized with Sophie Godin-Beekmann the 30th anniversary of the Montreal Protocol in Paris, France (2017).
Has created from zero the WMO Northern Hemisphere Ozone Mapping Center (1991), which has served the international scientific community. This service has been appreciated by the WMO RA-VI Congress (2-13 May 1994) and by the European Commission particularly during 1995-1996 in which reliable satellite observations were not available. Has acted as author, contributor, or reviewer in almost all WMO/UNEP Scientific Assessments of Ozone Depletion. Co-authored more than 20 WMO related reports and has established, in collaboration with WMO, the WMO “Professor Mariolopoulos Award”, created in 1996 and a WMO trust fund was created, fully financed by the Mariolopoulos-Kanaginis Foundation.
