Observational evidence for the convective transport of dust over the Central United States
Listed in National Center for Atmospheric Research
Bulk aerosol composition and aerosol size distributions measured aboard the DC-8 aircraft during the Deep Convective Clouds and Chemistry Experiment mission in May/June 2012 were used to investigate the transport of mineral dust through nine storms encountered over Colorado and Oklahoma.
Description
Measurements made at low altitudes ( â9âkm MSL). Storm mean outflow Ca2+ mass concentrations and total coarse (1âµmâ â50âµm) ice particle number concentrations was not evident; thus, the influence of ice shatter on these measurements was assumed small.
Mean inflow aerosol number concentrations calculated over a diameter range (0.5âµmâ<âdiameterâ<â5.0âµm) relevant for proxy ice nuclei (NPIN) were ~15-300 times higher than ice particle concentrations for all storms. Ratios of predicted interstitial NPIN (calculated as the difference between inflow NPIN and ice particle concentrations) and inflow NPIN were consistent with those calculated for Ca2+ and Vc and indicated that on average less than 10% of the ingested NPIN were activated as ice nuclei during anvil formation.

Deep convection may therefore represent an efficient transport mechanism for dust to the upper troposphere where these particles can function as ice nuclei cirrus forming in situ.
