  1. The CIRES-NOAA connection viewed from both sides Steve Montzka NOAA* *also a CIRES Fellow

  2. Why did I choose CU for graduate work? My 1992 entry in the Montzka family genealogy: “…being an idealistic young man… wanting to save the world..., I became interested in environmental studies. This led me to major in chemistry and enabled me to become proficient in measuring chemical compounds in the air and water.” CU and CIRES were the perfect fit… Strong environmental science component to research… developing techniques for measuring a range of organic gases and aerosols, rate constants of atmospheric reactions, and exploring the issue of nuclear winter... The meaningful and interesting work ongoing at CU and in CIRES was a major reason I came to Boulder…

  3. Prof. Sievers’ group circa 1983 As a CU/CIRES graduate student… I gained valuable experience in: * how to conduct research * chromatography * atmospheric measurements of hydrocarbons

  4. My first CIRES seminar...

  5. Fred Fehsenfeld Paul Goldan …and Michael Trainer (CIRES then) as mentors. An equally important part of my CU/CIRES graduate career: being exposed to the broader atmospheric science community in Boulder. Boulder was the center of the universe for scientists tackling the most significant atmospheric environmental problems of the day:  stratospheric ozone depletion  tropospheric ozone formation  delineating the role of natural vs anthropogenic factors in acid rain and oxidant formation… (do trees cause more pollution than automobiles?) This led to me take a NRC post-doc position at NOAA with Fred F. and Paul G. * Measuring aldehydes, ketones, and a furan formed from isoprene oxidation. * Identifying a new chemical emission from plants (2-methyl-3-buten-2-ol).

  6. The Elkins’ group at NOAA/CMDL (early 1990s) ‘Monitoring’ ozone-depleting gases in the atmosphere Then and now, more than half of the group are CIRES employees!

  7. • • SUM • Daily MHD Bi-wkly (Aircraft) • • THD HFM Global Halocarbon Cooperative Sampling Network • • • Flasks: ALT • Weekly BRW • • LEF • • • • WLG NWR • In Situ: • WIS • Hourly MLO KUM • • SMO • CGO • PSA • • SPO

  8. troposphere stratosphere 1980 level The spoils of atmospheric monitoring: The ozone hole and ozone-depleting substances... Less than 10 years after the Montreal Protocol on Substances that Deplete the Ozone Layer was ratified, OZONE-DEPLETING HALOGEN CONCENTRATIONS START TO DECREASE! The Montreal Protocol was working! The design and approach of the Montreal Protocol allowed it to be successful... …and have implications for policies limiting climate change. Policy-relevant science from the NOAA-CIRES collaboration 1996 www.esrl.noaa.gov/gmd/odgi/

  9. CH4 ODSs N2O HFCs The spoils of atmospheric monitoring (part 2): Ozone-depleting substances are also greenhouse gases Global-scale emissions can be derived from NOAA’s global observations The Montreal Protocol has had substantial climate benefits...

  10. Our Goal: Not only monitoring, but also improving understanding and predictive capabilities… CIRES provides NOAA added flexibility and the capability to address fundamental questions of interest Outcome: improved science and more accurate information to policy makers. Hemispheric CH3Br, ongoing obs. NH SH *How significant are industry-derived emissions of methyl bromide? (1994) *What were the concentrations of ozone-depleting substances before the 1930s? (1999) *How stable is the atmosphere’s cleansing capacity? (2001 and 2011) *Can carbonyl sulfide help quantify rates of photosynthesis? (2007) NOAA/GMD data

  14. Communicating scientific results to a wider audience through Scientific Assessments: “Supplying policy-relevant but policy-neutral information” -Dan Albritton

  15. In summary: As a student: CIRES made CU unique and attractive to me CIRES-NOAA connections enhanced my education tremendously Now that I’m at NOAA: CIRES employees are integral to NOAA/GMD research – they provide the means to explore key science questions – without the capabilities CIRES affords, NOAA/GMD would be severely hampered... – the NOAA-CIRES relationship greatly enhances my professional life at NOAA! Many thanks to collaborators and colleagues, friends and family.
