Aerosol Size Distributions Measured at the South Pole during ISCAT
Listed in NASA Earthdata CMR
This data set contains the physical aerosol size distributions measured at the South Pole during December 1998 and December 2000.
Description
The size range covered by these measurements was 3 [nm] to 250 [nm] in 1998 and 3 [nm] to 2000 [nm] in 2000. For 1998 measurements, total particle concentration for Dp > ~ 3[nm] and concentrations for 3 [nm] < Dp < 10 [nm] is available from 12/01/1998 to 12/31/1998 except over 12/09/1998 ~ 12/13/1998.
They measured by the prototype Ultrafine Condensation Particle Counter, equipped with Pulse Height Analysis (PHA-UCPC) Particle size distributions for 10 [nm] < Dp < 250 [nm] is available from 12/16/1998 to 12/31/1998. They were measured by a Scanning Mobility Particle Spectrometer. For 2000 measurements, total particle concentration for Dp > ~ 3[nm] and concentrations for 3 [nm] < Dp < 10 [nm] is available from 12/01/2000 to 12/29/2000 except over 12/22/2000 ~ 12/24/2000.

They measured by the white-light 3025 Ultrafine Condensation Particle Counter, equipped with Pulse Height Analysis (PHA-UCPC) Particle size distributions for 10 [nm] < Dp < 250 [nm] is available from 12/01/2000 to 12/29/2000. They were measured by a Scanning Mobility Particle Spectrometer. A PMS LASAIR measured particle size distributions for 100 [nm] to 2000 [nm] from 12/01/2000 to 12/29/2000.
Typical data collection frequencies are ~ 5 minutes in all instruments. All length(size) units are in [um]. Following are the meanings of the variables. concentration [#/cc]: number of particles in a cubic centimeter of air. surface area [um^2/cc]: surface area concentrations of particles, assuming all particles are sphere. volume [um^3/cc]: volume concentrations of particles, assuming all particles are sphere
