Arlyn Andrews leads the Carbon Cycle Greenhouse Gases group within NOAA's Global Monitoring Laboratory. She has measured carbon dioxide from Earth's surface to the stratosphere using a variety of diverse platforms, including NASA's ER-2 aircraft -- a modified U-2 spy plane, high-altitude balloons, and very tall broadcast towers. Arlyn earned her Ph.D. in Earth and Planetary Science from Harvard University in 2000 and then spent a few years at NASA Goddard Space Flight Center, where she contributed to the initial development of concepts for active and passive CO2 satellite sensors.
Arlyn joined the NOAA Global Monitoring Laboratory in 2003 and assumed responsibility for in situ measurements from tall towers within the NOAA Global Greenhouse Gas Reference Network. She developed the NOAA's CarbonTracker-Lagrange regional modeling framework for estimating greenhouse gas emissions and removals, with a particular emphasis on understanding uptake of carbon dioxide by terrestrial ecosystems. Arlyn has been an active participant in the U.S. Interagency North American Carbon Program since its inception. She served on the Climate Variability and Change panel supporting the Decadal Survey for Earth Science and Applications from Space (ESAS 2017), and she is a member of the NASA Carbon Monitoring System Science Team and the NASA Orbiting Carbon Observatory Science Team.
Betsy Andrews' research focus is on in-situ aerosol optical properties for the National Oceanic and Atmospheric Administration (NOAA) Earth Systems Research Laboratory's (ESRL) Aerosol Group. This program is dedicated to measuring and understanding aerosol characteristics relevant for climate change. The approach is to make aerosol measurements at a wide variety of sites across the globe in order to encompass various aerosol types (e.g., dust, smoke, sea salt, etc.) and regions (e.g., Asia, Arctic, etc). Currently, Betsy is very involved in using these measurements of the surface in-situ measurements of aerosol optical properties to evaluate global climate model simulations of aerosols.
Bio:
Betsy received her Ph.D. in 1996 from the Civil and Environmental Engineering Department at University of Illinois, Urbana-Champaign for her studies of aerosol hygroscopicity in an electrodynamic balance. She followed her graduate work with two post-doctoral fellowships. The first was at Colorado State University studying aerosol-cloud interactions with Dr. Jeffery Collett and Dr. Sonia Kreidenweis. The second was an NSF funded project at University of Northern Colorado investigating factors influencing low-income students' participation in STEM fields. Since 1999, Betsy has been a research scientist with the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado in Boulder, CO. Betsy's over-arching research focus is aerosol optical properties, but some specific aspects she's explored include aerosol climatologies across a variety of site types (e.g., Arctic, mountain, continental) and platforms (surface and airborne). In addition to climatological studies which have looked at temporal patterns in aerosol data, she's also investigated trends in long-term measurements. Additionally, in order to better characterize measurements, Betsy has participated in instrument intercomparison experiments and investigated relationships between remote sensing and in-situ aerosol optical properties.

Job Titles:
- Team Member of the Quarter Award
Dr. Ben Miller received the GMD Team Member of the Quarter Award in November 2019 for his pioneering work related to a short-term study on the "Colorado Front Range Air Toxics Study, 2018-2019". He developed novel techniques for analyzing samples of trace gases with a wide dynamic range in concentration above ambient levels while ensuring that the samples do not contaminate our long-term mission of providing accurate measurements of these trace gases in the background atmosphere. Working with others, Dr. Miller provided a pathway to link our central ambient atmospheric real air, working standard from Niwot Ridge, CO to high concentration gravimetric standards and to a spiked high concentration standard of real air from Niwot Ridge (working standard). This accuracy will permit the calculation of highly precise emission factors of a VOC compared to methane to determine its source of the emission (landfills, cattle feedlots, fracking, biomass, etc.). This allows GMD to identify the source of enhanced methane and VOCs and to assist public policy makers who work on emission management and mitigation for the public good.

Dr. Colm Sweeney is the Associate Director of Science for NOAA's Global Monitoring Laboratory (GML) and the Lead Scientist for GML's Aircraft program. Prior to joining GML, he was a Research Scientist at Princeton University and NOAA's Geophysical Fluid Dynamics Laboratory. He holds a PhD in chemical oceanography from Columbia University's Lamont-Doherty Earth Observatory and BA in chemistry from Bowdoin College.
Dale F. Hurst earned his Bachelor of Science degree in chemistry (cum laude) from the University of California, Irvine (UCI), in 1983. This was followed by Masters of Science (1987) and Doctor of Philosophy (1990) degrees in chemistry, with specialization in atmospheric chemistry, under the research supervision of Professor F. Sherwood Rowland at UCI. Dale's Ph.D. dissertation "Seasonal Variations in the Latitudinal Distribution of Tropospheric Carbon Monoxide, 1986-1988" provided him with ample opportunities to travel to Pacific islands and New Zealand, collecting air samples for research.
In 1990 Dale was awarded a 3-year Australian Research Council Fellowship to study trace gas emissions from biomass fires in Australia with Dr. David Griffith at the University of Wollongong. Dale was part of two field campaigns in northern Australia that employed aircraft to sample smoke from savanna fires. Back in the home laboratory, he analyzed the smoke samples for numerous trace gases using gas-phase and matrix-isolation Fourier-transform infrared (FTIR) spectroscopy. His favorite part of this was living in Kakadu National Park during the second field campaign, which was conducted at an ecological fire study site (Kapalga Station) within the Park.
In mid-1993 Dale was awarded a National Research Council (USA) Fellowship at NOAA/CMDL to build an automated 4-channel gas chromatograph (GC) for operation at a tall (496 m) tower in Grifton, North Carolina. Autonomous GC measurements of 12 trace gases from three heights on the tower began in late 1994. In 1995 he built a similar GC for a second tall tower (Park Falls, WI). Though in rural areas, these towers were intermittently influenced by pollution from distant urban centers. The GC data were used to quantify regional emissions of halocarbons and other anthropogenic gases, as well as to document a reduction in the variability of halocarbon mixing ratios that implied their U.S. emissions were diminishing because of the Montreal Protocol.
Dale was the lead scientist for the 4-channel Airborne Chromatograph for Atmospheric Trace Species (ACATS-IV) from September 1997 through December 2004, and worked to steadily increase its measurement quality and dependability for airborne science missions. During this period ACATS-IV was deployed on the NASA ER-2 aircraft for the 1997 POLARIS (Fairbanks, AK) and 2000 SOLVE (Kiruna, Sweden) missions, the University of North Dakota Cessna Citation II aircraft for the 2003 COBRA-North America study (USA and Canada), and the Trans-Siberian Railway for the 2001 TROICA-7 and 2004 TROICA-8 expeditions. Each of the two Russian expeditions included a two-week train ride from Moscow to Khabarovsk (and back), a 17,000-km round trip. These rail journeys were a unique way to see the vastness of Russia.
Dale began work in early 2005 to fly a 2-channel GC, the Unmanned Aircraft Systems (UAS) Chromatograph for Atmospheric Trace Species (UCATS), on the Altair UAS. His work with UCATS resulted in a very successful NOAA UAS demonstration project in October 2005. Several months later, in summer 2006, UCATS successfully flew on Altair again for the USDA Forest Service FIRE mission. During these two UAS missions UCATS amassed more than 120 hours of high-quality trace gas measurements, including four flights of long (>18 hrs) duration. In April 2007, Dale and colleagues were awarded a "Bronze Team Award" for their pioneering work demonstrating the utility of UAS in making in situ measurements of trace gases.
In spring 2008, the Stratosphere-Troposphere Analysis of Regional Transport (START-08) project introduced Dale to yet another class of airborne platform for in situ measurements of trace gases - the NSF Gulfstream-V aircraft. This large executive jet has tremendous airborne capabilities that allowed it to probe the mid-latitude tropopause region, looking for signs of anomalous atmospheric transport. Dale operated and maintained UCATS for the 120 research flight hours, often while seated just behind UCATS in the aircraft cabin. Overall, UCATS produced quality trace gas, ozone, and water vapor data for 17 of the 18 science flights of START-08.
In September 2009, Dale switched gears and became the water vapor project leader for the ESRL Global Monitoring Laboratory. His main duties now include: continuing to improve the NOAA-built balloon-borne cryogenic frost point hygrometer (FPH) and overseeing the ongoing 28-year-old record of stratospheric water vapor soundings over Boulder (with the FPH). Every two weeks we launch a weather balloon carrying a FPH, ozonesonde, and radiosonde from Boulder (since 1980) and Lauder, New Zealand (since 2004). These water vapor vertical profile data, especially in the upper troposphere and stratosphere, may provide important clues about shifts in atmospheric circulation as a result of climate change.
Dale has received several awards for his scientific and outreach work including the American Institute of Chemists Award (1983), Outstanding Student Speaker Award, UC Irvine (1989), membership in Phi Beta Kappa and Phi Lambda Upsilon (1983), and six different NASA Group Achievement Awards (1993-2008). In 2000, he and three colleagues were awarded the Award of Excellence from the CIRES Members' Council. His first-authored paper "Emissions of ozone-depleting substances in Russia during 2001" was selected as an Outstanding Scientific Paper for 2005 by the NOAA Office of Oceanic and Atmospheric Research.

B.S.M.E. The University of Colorado (Boulder), 2003
I am the lead scientist for the UAS Chromatograph for Atmospheric Trace Species (UCATS), a lightweight and compact two-channel gas chromatograph with additional capabilities for ozone and water vapor. This instrument was designed for operation on unmanned aircraft systems (UAS) but has also flown on other platforms, such as the NSF/NCAR GV and the NASA DC-8. I work on aircraft field projects to study atmospheric composition, dynamics (transport), and climate processes. Besides field work, I am involved with instrument design, building, and repair; data analysis, archiving data, and publication of results; and coordination and collaboration with the Water and Ozone group within the Global Monitoring Laboratory (GML) of NOAA as well as other colleagues in the NOAA Chemical Sciences Division and GMD.
My academic training was in the field of chemistry, and I received my Ph.D. in physical chemistry in 1989. I began work in atmospheric science as a postdoctoral researcher and scientist with Dr. James Anderson, working on water vapor, ozone, and stratospheric transport, primarily on a series of missions on the NASA ER-2 aircraft in the 1990's. After working as a research scientist at the Woods Hole Oceanographic Institution, and as a Program Director for Atmospheric Chemistry at the National Science Foundation, I came to NOAA in 2009.
Since then, I have participated in the HIPPO and ATom projects to study the distribution, chemistry, and transport of atmospheric trace gases over the Pacific ocean from the NSF GV aircraft and the Pacific and Atlantic with the NASA DC-8, respectively. The ATom project is ongoing, with circuits over the ocean planned for winter 2017, fall 2017, and spring 2018. From 2010-2014, I operated the UCATS instrument on the NASA/NOAA Global Hawk UAS from California and Guam during GloPac and the Airborne Tropical TRopopause EXperiment (ATTREX). Highlights of ATTREX include the use of trace gases to determine the origin and transport of air in the Tropical Tropopause Layer (TTL), and observations of ozone over the tropical Pacific. Recent reports have suggested a region of extremely low ozone and possibly low concentrations of the hydroxyl radical over the western tropical Pacific, which could lead to the transport of short-lived halogen compounds (primarily organic bromine compounds) into the stratosphere, where they break down and destroy ozone. Results from ATTREX, which are nearing publication or already published, provide new evidence on ozone and bromine distributions, and the transport and chemistry of these compounds in the tropics.
