EARTH SYSTEM SCIENCE
"Biological Interactions with Global Atmospheric Chemistry," T.
Rosswall (Royal Swedish Acad. Sciences, Box 50005, S-10405 Stockholm, Sweden),
Ambio, XIX(2), 100, Apr. 1990.
Summarizes four research categories and their goals, developed in a recent
IGBP workshop: (1) natural variability and anthropogenic perturbations of
tropical atmospheric chemistry and biospheric interactions; (2) role of tundra
and boreal regions in biosphere-atmosphere exchanges; (3) global distribution,
transformations, trends and modeling; and (4) trace gas fluxes in mid-latitude
"Dynamical Perturbations to the Ozone Layer," M.L. Salby (Dept.
Atmos. Sci., Univ. Colo., Boulder CO 80307), R.R. Garcia, Physics Today,
43(3), 38-46, Mar. 1990.
Presents an overview of dynamical disturbances, focusing on how they alter
the global distribution of ozone through horizontal and vertical transport.
Reviews the basic climatology of ozone. Describes the essential mechanics of
planetary waves and then uses detailed transport calculations to investigate how
these disturbances can influence the abundance and distribution of ozone.
"Biogeophysical Remote Sensing--A Ground Truth Data Base and
Graphics System for the Northwestern Pacific Ocean," A. Harashima (Nat.
Inst. Environ. Stud., Japan Environ. Agency, Tsukuba, Japan), Y. Kikuchi, Eos,
p. 314, Mar. 6, 1990.
Personal computer software has been developed for searching routine
station-based observations of phytoplankton pigments and other chemical
components of ocean water, to systematically calibrate satellite measurements
and to visualize biogeochemical processes in the ocean interior by generating
3-D perspective views of ocean parameters. Explains two basic problems of
quantitative analysis and how to deal with them.
"Haze and Other Aerosol Components in Late Winter Arctic--Alaska,
1986," S.-M. Li (Atmos. Chem. Div., NCAR, Boulder CO 80307), J.W.
Winchester, J. Geophys. Res., 95(D2), 1797-1810, Feb. 20, 1990.
Results from concurrent aerosol elemental measurements by proton-induced
X-ray emission (PIXE) analysis show three coarse and five fine aerosol
components of different elemental compositions at Barrow, Alaska. Results show
that certain winter meteorological conditions favor pollutant transport from
lower latitudes to the Arctic. While haze is related to industrial pollutants,
other nonpollution products are present in the winter Arctic and may be
important constituents of haze.
"The Global Hydrologic and Energy Cycles: Suggestions for Studies in
the Pre-Global Energy and Water Cycle Experiment (GEWEX) Period," J.L.
Kinter (Dept. Meteor., Univ. Maryland, College Park MD 20742), J. Shukla, Bull.
Amer. Meteor. Soc., 71(2), 181-189, Feb. 1990.
Validation of general circulation model calculations of the seasonal cycle
of water and energy fluxes between atmosphere and ocean, and between atmosphere
and land, may be carried out in four ways: (1) Use the existing operational
analyses of atmospheric data from the National Meteorological Center and the
European Centre for Medium-Range Weather Forecasts; (2) create a set of
reanalyzed data from the historical record to broaden the data base; (3) use a
long integration of the most realistic, high-resolution GCM available to compare
to the first two data sets; (4) repeat calculations when observations from
GEWEX, TRMM and Eos missions are available.
"A Discussion on the Predictability of Global Change," D. Ye
(Chinese Acad. Sci., Beijing 100864, PRC), F. Cong-bin, Clim. Change,
15(3), 483-486, Dec. 1989. Discusses a number of factors relevant to the
International Geosphere-Biosphere Program goal of predicting changes in the
"Temporal Variations in Tempestite Thickness May Be Geologic Record
of Atmospheric CO2," D.S. Brandt (Dept. Geog., Eastern Michigan Univ.,
Ypsilanti MI 48197), R.J. Elias, Geol., 17(10), 951-952, Oct.
If tempestite thickness, storm intensity, and CO2 are causally linked,
greenhouse phases should correspond to deposits of thick tempestites (more
intense storms) and icehouse phases should be characterized by comparatively
thin tempestites (less intense storms). Tempestite thickness data provide a test
of the greenhouse-icehouse model, and initial results suggest general agreement
with the independently derived climate (CO2) curve for the latest Precambrian
"Infrared Radiation Fluxes in the Presence of Cirrus Clouds,"
Ye.M. Feygel'son (Inst. Atmos. Phys., USSR Acad. Sci.), Izvestiya, Atmos.
Ocean. Phys., 24(6), 1988. (Eng. ed. pp. 430-435, Dec. 1988; publ.
Discusses the fundamental difficulties and source error in practical
calculations of integral fluxes of thermal radiation in the presence of cirrus
clouds. Determines the contribution of the gas component to their emissivity,
and proposes a method of correcting for reflection of undercloud thermal
