Abstract: Pollution effects on cloud condensation nucleus (CCN) concentration vary widely, sometimes even decreasing the CCN. The interpretation of these pollution effects may be invalid if the nuclei are measured by expansion-type ...

Abstract: During the 1965 Project Stormfury experiments a combination of six cloud physics aircraft instruments were used to measure the changes in the water-ice budget in a large tropical cumulus which had been seeded. Pyrotechnic ...

Abstract: An aircraft instrument which provides continuous replication of water droplets and ice particles as an aircraft traverses a cloud is described. The instrument makes use of a continuously moving 16-mm film on which a Formvar ...

Abstract: A long-lived cumulus cloud off the southern coast of Australia was found to contain ice crystals, even though the coldest temperature in it was about ?4C. Two instrumented aircraft made successive passes through the cloud ...

Abstract: Measurements of the number density, volatility and supersaturation spectra of CCN during aircraft soundings to about 15,000 ft MSL over Arizona, Central Pacific, Alaska, and in a convective region over Florida, and on five ...
