DRI Near-Surface Below Cloud Base CCN Data

Cloud Condensation Nuclei (CCN) measurements obtained by the Desert Research Institute (DRI from the NCAR C-130 during ACE-1 during periods at low altitudes below the cloud base. Concentrations are per cubic centimeter normalized to sea-level pressure.This is directly obtained because a mass flowmeter was used to measure the sample into the cloud chamber.
