Research overview:
Richard Healy, an information systems associate and manager
of the NOSAMS computer network and web site, collaborates
with the NASA/Goddard Institute for Space Studies (GISS) climate-modeling
group in New York. One aspect of the research is modeling
for the Analysis of Recent and Rapid Climate Change (ARRCC)
program. Working with the GISS general circulation model,
the observed sunspot activity during the past 500 years has
been used to estimate changes in solar irradiance and their
correlation with changes in global surface air temperature
(Robertson et al., 2001). The latest simulations additionally
involve the use of globally measured carbon and sulfate aerosols
as well as historical estimates of volcanic, stratospheric
aerosols and trace gases (CO2, N2O,
CH4). In addition, Mr. Healy has been running the
coupled ocean-atmosphere GISS model using the IPCC scenarios
A2 and B2.
Additional work with collaborators at NASA/Goddard Space Flight
Center (GSFC) and at the Lamont-Doherty Earth Observatory
has dealt with climatic responses to changes in sea ice coverage
(Parkinson et al., 2001). With collaborators at the University
of Massachusetts at Amherst, Mr. Healy has been working to
simulate 18O tracers in
the atmosphere using the GISS model to compare with values
of δ18O in ice cores in the Andes and to compare with
the ECHAM model in tropical South America. Two manuscripts
have been published in the Journal of Geophysical Research
(Vuille et al., 2003a, 2003b).
