Scientists from the University of Berkeley in California, the University
of San Diego in California, the University of Manchester in England,
Tom Duck from Dalhousie University in Halifax and people from NOAH in Bolder
Colorado and people from CMDL {Climate monitoring & Diagnostic Lab,
have set up their instruments on one of the most southerly tips of Canada,
Chebougue Point, Yarmouth, Nova Scotia. Over a period of about 10
weeks they collected data on atmospheric pollutants that travel through
this location. Others studies may be done in New England and on Sable Island
Allan's Educational background
|
The team was led by a Allan Goldstein from Berkeley University in California.
Allan can be seen on the left with his son, who is impatiently waiting
for his dad to take him and his mom and his brother on a picnic.
This is where I came in. Right in the middle of the little guys adventure
with his dad. He had come all the way from California to be with
his dad and some short, fat, bearded frenchmen, probably not Santa, was
obstructing justice. His right to be with his dad.
Despite this Mr. Goldstein took the time to show us around the site, and to explain what they were trying to accomplish. In this brief video (50043 k) Allan explains the purpose of their visit to Nova Scotia. |
Brief Overview
One set of instruments detects sound waves that bounce back to detection equipment that gives a vertical profile of the pressure and temperatures of various levels of the atmosphere. Other sensors emit a green light that enables them to measure the height of the clouds, and the layers of aerosols in the atmosphere. Other trailers on the site are measuring ozone, carbon monoxide, and hydrocarbons collected from a tube at the top of 10 meter tower.. "We care about aerosols in the atmosphere because they can affect human health and visibility," said Allen Goldstein(S) It will be some time before the data is finalized but it will be available through Noah web site.. |
The young scientist on the right, one of Allan's students from Berkeley,
designed equipment and software to analyze the compounds in the atmosphere.
This computer is hooked up to a mass spectrometer that can evaluate the
levels of various hydrocarbons.

Tom Duck of Dalhousie University will be involved with evaluating Lidar measurements of cloud and aerosol backscatter, depolarizaton, and extinction, and possibly water vapor, sun photometer. |
The amount of instrumentation they brought with them was amazing. Computing power that was probably a billion times greater then what it took to get man to the moon was crammed into several trailors that we on Chebogue Point. Pictured below is a small sample. |
