Expertise: Atmospheric Chemistry and Climate Change

Professor Talbot’s interests encompass regional-to-global scale atmospheric circulations and associated transport of trace constituents. His research areas include: distribution, speciation, and chemistry of mercury in the Earth’s atmosphere; intercontinental transport of trace gases and aerosols; regional tropospheric chemistry and climate change in southeastern Texas; climate-air quality connections; biosphere-atmosphere exchange of trace gases; and development of advanced instrumentation for the measurement of reactive trace gases and aerosols (ground and aircraft platforms). He is Professor of Atmospheric Chemistry and Director of the Institute for Multidimensional Air Quality Studies. Dr. Talbot is also an adjunct Professor of Atmospheric Chemistry in the School of Atmospheric Science at Nanjing University, Nanjing, China. He also serves there as Vice Chair for the Institute for Climate and Global Change Research at Nanjing University.

He received his Ph.D. from the University of Wisconsin – Madison in 1981, and was subsequently awarded a National Academy of Sciences NRC postdoctoral fellowship at NASA Langley Research Center. His work on diverse topics has appeared in more than 250 papers in high-impact professional journals and he is in the top 0.5% of researchers in Geosciences for citations to his publications (selected as an ISI Highly Cited Scientist).

Dr. Talbot has been part of the NASA Global Tropospheric Chemistry program since 1983, serving on the science team for 20 major airborne expeditions supported by this program. He was also chief scientist for the NOAA-AIRMAP program which focused on understanding regional atmospheric chemistry, dynamics, and climate change in New England. In collaboration with NOAA, AIRMAP conducted the New England Air Quality Study in 2002 (http://www.esrl.noaa.gov/csd/NEAQS/) and the international follow-up study, ICARTT 2004 (www.esrl.noaa.gov/csd/ICARTT), which involved hundreds of scientists and 13 research platforms from NOAA, NASA, DOE, and several European partners. He has received NASA Group Achievement Awards for five airborne expeditions and was selected for inclusion in the AcademicKeys Who’s Who in Sciences Higher Education. He has spoken at numerous press conferences involving the President of UNH, the New Hampshire Governor, Admiral Conrad Lautenbacker of NOAA, various NASA upper level administrators, and Senator Judd Gregg.

On the national scene he has chaired special sessions at AGU meetings, served as the UNH Member’s Representative to the University Corporation for Atmospheric Research, served on the Membership Committee of UCAR, chaired that committee for several years, served as an evaluator for the MacArthur Fellowship Program, served on NSF and EPA review panels, and been an external evaluator for promotion/tenure at a number of institutions.

Internationally he has served as a nominator/evaluator for the Kyoto Prize in Basic Sciences (Japan), the State Natural Science Award (Peoples Republic of China), Japan Prize (Japan), and the Natural Environment Research Council (United Kingdom). He serves on the editorial board of several international journals, has been a guess editor of journal special issues, and led the 2006 review of the Australian CSIRO divisions working on climate and air quality.

Our group consists of:

Robert Talbot - Professor of Atmospheric Chemistry
Patrick Laine – Postdoctoral Fellow (mercury measurements)
Xin (Lindsay) Lan – Ph.D. Student (regional modeling)
Dara Feddersen – Ph.D. Student (mercury measurements)

Huiting Mao – Associate Professor of Environmental Chemistry
Casey Hall – Ph.D. Student (mercury measurements)
Zhuyun Ye – Ph.D. Student (mercury modeling)

We started measuring atmospheric mercury in 2003 at Thompson Farm in New Hampshire.  The site is still operating today with funding from EPA.  It is a site (NH06) in the Atmospheric Mercury Network (AMNet).  Information on this program can be found here http://nadp.sws.uiuc.edu/amn/.  We now also operate measurement sites in Syracuse, NY and Houston, TX.
The goal of our research is:

  • To understand the sources, sinks, and chemical transformations of atmospheric mercury on regional-to-global scales.
  • Improve the analytical methodologies for measuring atmospheric mercury.
  • Improve emission inventories for mercury.
  • Improve simulations of mercury with the 3-d regional model CMAQ.
  • We have developed our own custom box model for studying chemical transformations of atmospheric mercury.
  • We have fabricated a custom instrument to measure mercury with one minute time response.
  • We were one of the first groups to measure mercury from an airborne platform.

Mercury is a serious environmental toxin that is distributed globally by large-scale atmospheric circulations.  In the atmosphere mercury exists in diverse chemical forms that are comprised of gaseous elemental mercury (Hgo), reactive gaseous mercury (RGM = HgCl2 + HgBr2 + HgOBr +. . .), and particulate-phase mercury (HgP).  Near the Earth’s surface Hgo is observed ubiquitously with contemporary mixing ratios at the several hundred parts per quadrillion (ppqv) level, with RGM and HgP comprising only a few percent of the total mercury.

Units:  1 ng m-3 = 112 ppqv = 3 × 106 molecules cm-3 of Hgo

The global chemical transformations we are studying are depicted in the figure below.  The uncertainties are numerous.  The Houston area in particular has numerous large sources of atmospheric mercury.  We would like to develop chemical fingerprints of specific sources using stable Hg isotopes.  We hope to do this using a small aircraft to sample individual plumes.  We also hope to develop a methodology for measuring individual RGM species using chemical ionization mass spectrometry (CIMS).

Our research has shown that:

  • Hgo is depleted to zero in the stratosphere.

 

  • Hgo is depleted to near zero near the surface over the Arctic Ocean in springtime and it is related to the occurrence of atomic halogens.
  • Hgo has strong seasonality with the lowest mixing ratios in early fall and highest in early spring.

 

  • The seasonality in Hgo is consistent across large portions of the U.S.
  • In rural locations Hgo exhibits a strong diurnal cycle with the lowest mixing ratios in early morning.

 

  • Over the ocean, RGM is highest in midday, and lowest at night while Hgo exhibits the opposite pattern.
  • In summer HgP is associated primarily with coarse (>1µm) aerosols, but in winter this switches to the fine fraction (<1µm).

 

  • HgP is not removed from the atmosphere efficiently by snow.
  • Hgo exhibits strong correlation with carbon monoxide (CO), especially in wintertime.

 

  • The diurnal cycle of Hgo is facilitated greatly by uptake in the water layer of aerosols and dissolution into dew on Earth’s surfaces.
  • The Houston area experiences large and numerous excursions above the Northern Hemispheric background level of ~160 ppqv.

 

  • RGM is not a “sticky” gas.  In fact, it’s very difficult to remove from an ambient air stream.
