It is often said that one person's signal is another person's noise, and that is certainly the case when one wishes to locate where a cloud-ground lightning stroke has contacted the earth's surface. The crackle often heard on an AM radio during a thunderstorm is the "noise" providing the signal we use to locate lightning with our single-station system, one of which is mounted on the Meteorology Department's Walker Building above the Weather Station. The rapidly heated lightning channel is an excellent transmitting antenna, radiating power from the huge transient current over a wide range of frequencies from below the AM to above the FM radio bands. Professor Shirer is studying ways to effectively range lightning up to several hundred kilometers distance by using the power in the AM band that is received by lightning locator system.

of the ForestKen Davis studies carbon dioxide concentration and transport above forests in northern Wisconsin and the Upper Peninsula of Michigan as part of the Chequamegon Ecosystem -Atmosphere Study (ChEAS). His research involves determining the rates and causes of carbon dioxide storage and emission in these areas. Is it true that as our forests mature, they soak up less carbon dioxide?

PBS'
News Hour with Jim Lehrer airs story about massive air pollution
study involving Penn State Meteorology scientists. The
study, called ICARTT, involved six countries, 25 universities, NOAA, NASA,
and private foundations. Bill Brune and his research team (Bob Lesher,
Xinrong Ren, Jingqui Mao, and Robert Long) participated in the research
mission, which took place this summer off the coast of New Hampshire. |

MMS Profiler System fielded to active US Army units and approved to enter full rate production
In the past year (April 2004 through March 2005), the Meteorological Measurement Set (MMS) Profiler program successfully completed Developmental Test and Initial Operational Test. The software was qualified and Profiler systems have been fielded to active US Army units. The program was recently approved to enter full rate production; this is the last major milestone of the development contract. The Penn State University team led by Dr. Stauffer was responsible for the following major tasks during the above period:

![]() The Site Scientist Team for the Department of Energy Atmospheric Radiation Measurement Program consists of four of our faculty, a research assistant and two graduate students. The research of this group focuses on Arctic weather, primarily clouds and their interaction with radiation, and revolves around the long-term DOE-ARM remote sensing sites at Barrow and Atqasuk, Alaska. |

Interpretation
of Probabilistic Weather Forecasts. In collaboration
with Andy
Kleit (PSU Department of Meteorology economist) and Gary
Bolton (PSU Smeal College of Business), Mark
Roulston is designing experiments to be conducted at PSU's Laboratory
for Economic Management and Auctions. The focus of this research
is to investigate how people perceive weather forecasts that contain
probabilistic information and whether such forecasts improve their decision
making.

Ray Najjar and graduate students Kathy Bailey and Karen Tinkelpaugh
were aboard the Research Vessel Seward Johnson in the subtropical North
Atlantic Ocean to study the cycling of dimethylsulfide (DMS), a gas
formed by marine plankton. DMS is thought to be the main precursor of
sulfate aerosols, which play a key role in cloud formation and hence
climate. ............................................................................. |
