The project measured condensation nuclei concentration in particles per cc.
How does this program work?
The instruments involved, a garden counter and sunphotometer, were designed by Steven Ryan and constructed by high school students and teachers in 2001. Measurements were made by six high schools around the Big Island plus downtown Hilo. These locations are indicated in the diagrams below.
Why is this research important?
VOGNET was an educational outreach program for high schools. It contributed to long term monitoring of volcanic pollution around the island. The data can be used in studies of health effects of volcanic pollution.
Are there any trends in the data?
No trends. Pollution levels vary with changes in meteorological conditions and volcanic emission rates.
How does this program fit into the big picture?
What is it's role in global climate change?
