Abstract :
Measurements of condensation nuclei concentration in two size ranges and aerosol optical depth at two wavelengths have been made by VOGNET, a network of high schools located around the island of Hawaii. Between October 1996 and May, 1999 over 6000 measurements were made by students at five locations: Pahala, Kealakekua, Waimea, Hilo, and Pahoa. These data show how the particle concentration, size distribution, and aerosol optical depth varies around the island as a function of the prevailing wind direction and altitude above sea level. An automated condensation nuclei counter built for VOGNET measured the diurnal cycle of particle concentration at these sites
