General Information

Weekly ozonesondes are released from the balloon launch facility shared with the National Weather Service. From these sounding are obtained profiles of temperature, humidity, wind speed and direction, and ozone concentrations from sea level to 35 km altitude. This site is also the location for the MLO measurements of both wet and dry precipitation for the Hilo area. Hilo may have up to 200 inches (500 cm) of precipitation per year whereas the mountain site may have only 10% or less of that amount.
