Mortician becomes infected with TB from cadaver
Johns Hopkins researchers have reported the first known case of tuberculosis (TB) transmitted from a cadaver to an embalmer, according to a case study in the Jan. 27 issue of the New England Journal of Medicine. (2000-01-25)

Colorado State atmospheric scientist believes number of influences are overlooked in U.S. national and international climate assessments
A researcher at Colorado State University believes that regional assessments of climate change in the United States and one prepared by a United Nations panel overlook factors-- principally landscape and land-use changes--that are critically important to the realism of models of global climate change. (2000-01-09)

NASA Langley Research Center AMS tip sheet
NASA Langley Research Center scientists will report on new atmospheric science discoveries and areas of exploration at the American Meteorological Society meeting in Long Beach, California, from January 9-14. Details of scheduled papers and poster sessions follow. (2000-01-06)

Local and remote aerosol measurement techniques compared
The environmental effects of man-made atmospheric particles, known as (1999-12-12)

Feeding the world by cleaning the air: study ties heavy regional haze to reductions in China's crop production
A new study suggests that cleaning up the air may help to feed the world. Published in the November 23 Proceedings of the National Academy of Sciences, the study found that heavy regional haze in China's most important agricultural areas may be cutting food production there by as much as one-third. (1999-12-05)

Rain showers may be caused by vortices in the air
Clouds contain disproportionately large quantities of large and small water droplets, something which meteorologists were hitherto unable to explain. Dutch researchers have possibly discovered the reason: within areas of air turbulence there are spiral patterns a few centimetres in size, which may also explain why clouds produce rain. (1999-11-10)

'Soapy' droplets make brighter clouds
Organic properties of some pollution particles can increase the number of cloud droplets, allowing more sunlight than normal to be reflected into space. The phenomenon affects climate locally, and probably regionally, say researchers from the Consilio Nazionale delle Ricerche in Bologna, Italy, and the University of Washington in Seattle. (1999-09-16)

Ship sulfur emissions found to strongly impact worldwide ocean and coastal pollution
Ship emissions are a dominant contributor to atmospheric sulfur dioxide concentrations over much of the world's oceans and in several coastal regions, researchers from Carnegie Mellon University and Duke University report in a Nature article today. (1999-08-19)

Particulate matter causing air pollution
Scientists from around the world have gathered in Atlanta this month to determine the best ways to measure the fine particulate matter that is polluting the nation's air, particularly in large urban areas. (1999-08-16)

UW professor's climate change theory leads to NASA mission
For nearly a decade, University of Washington atmospheric chemist Robert Charlson has advanced the notion that, in some regions, submicron-sized particles from industrial pollution are actually countering the atmospheric warming effects of greenhouse gases. Now NASA is planning the PICASSO-CENA mission to gather crucial data to better understand the role of those particles in human-caused climate change. (1999-08-02)

Price for decreased acid rain may be increased global warming
Reducing future emissions of sulfur dioxide in an attempt to mitigate the acid-rain problem may aggravate the global- warming problem, a University of Illinois professor says. (1999-07-07)

Massive pollution documented over Indian Ocean
An international group of scientists has documented widespread pollution covering about 100 million square kilometers of the tropical Indian Ocean -- roughly the same area as the continental United States. (1999-06-08)

INDOEX Researchers Document The Impact Of Pollutants On Climate Processes Over The Tropical Indian Ocean
Scientists at the Max Planck Institute for Chemistry are participating in the international Indian Ocean Experiment (INDOEX) to study how air pollution affects climate processes over the tropical Indian Ocean. (1999-03-26)

Atmospheric Scientists Fly Over South Pacific To Sample "World's Cleanest Air"
Two research aircraft and 100 researchers are heading to the South Pacific to study what some have called the world's cleanest air. Researchers will gather data on the chemical species that affect formation of tropospheric ozone and sulfate aerosols. The goal is to determine how well the earth's atmosphere cleanses itself. (1999-03-08)

NCAR Scientists, Aircraft, Instruments Head To Indian Ocean For Climate ChangeExperiment; UCAR Directs Operations
The National Center for Atmospheric Research has sent researchers, instruments, and a C-130 research aircraft owned by NSF to the $25-million Indian Ocean Experiment (INDOEX) to study aerosols and climate change. The University Corporation for Atmospheric Research is overseeing operations. (1999-03-04)

Modeling Atmospheric Aerosols
Sponsored by the Office of Naval Research, a three-week experiment called Electro-Optical Propagation Assessment in Coastal Environments is currently underway to improve the atmospheric aerosol models for predicting infrared propagation near the ocean surface and in coastal environments. (1999-03-01)

First Chemical Analysis Of Polar Stratospheric Cloud Particles Successfully Achieved By Max Planck Scientists
An innovative balloon-borne experiment, developed at the Max Planck Institute of Nuclear Physics, Heidelberg, Germany, provided the first chemical analysis of polar stratospheric cloud particles (PSCs). PSCs are a crucial element in the development of the large scale ozone hole above Antarctica (Science, Vol 283, 12 February 1999). (1999-02-11)

Scientists To Kick Off Major Field Experiment On Role Of Aerosols In Climate Change
Pollutants known as aerosols play a role in cooling the planet and mitigating the effects of global warming. Scientists from around the world are now trying to find out how; the intensive field phase of an experiment sponsored in part by the National Science Foundation (NSF) is beginning next week. (1999-01-29)

Colorado State Leads $145 Million Spacecraft Project To Provide 3-D Images Of Clouds, Aerosols And Improve Weather, Climate Forecasting
Colorado State University will team with NASA's Jet Propulsion Laboratory and lead a $145 million, five-year NASA project to launch a satellite that can provide the first three-dimensional satellite pictures of clouds -- images that can dramatically improve weather forecasting. (1999-01-06)

NCAR Team Tags 'Imported' Pollutants Over The Pacific Northwest
From 50% to 60% of sulfate-aerosol pollution over the Pacific Northwest is coming from industrialized Asia, according to a model developed by a team of researchers at the National Center for Atmospheric Research. In contrast, sulfates in Europe are coming primarily from European sources. (1998-12-04)

New Studies Analyze Ozone Depletion
The obvious global decline in the ozone layer due to the rise in chlorofluorocarbons is marked by year-to-year and spatial variability. Several studies in the June 1 issue of Geophysical Research Letters, published by the American Geophysical Union, report and analyze recent studies. (1998-05-22)

Model Shows Certain Gasses Could Stimulate Global Cooling
New computer modeling suggests that global warming might not be entirely a product of human activity. The research shows that carbon and sulfur emissions can have the reverse effect, serving to cool down the planet. (1997-12-12)
