VOCALS: NSF/NCAR C-130 Aerosol CN (Cold, Hot, Ultrafine)


This data set contains total aerosol number concentrations with the following temperature, cut size and TSI Condensation Particle Counter (CPC) model: "Ultrafine CPC (UCN)", unheated particles > 0.003um, CPC model 3025; "Cold CPC (CNcold)", unheated particles > 0.01um, CPC model 3010; "Hot CPC (CNhot)": heated to 350 C, CPC model 3010.

Data for each flight is supplied in its own ASCII file. Filenames are structured as (for example): "CN_C130_20081109_R0withclouds.ict" indicates a file with possible droplets shutter events included and "CN_C130_20081109_R0.ict" indicates a file with droplets shutter events excluded. These data were collected during VOCALS on the NCAR C-130.
