Data Set Description:

NOAA ship Discoverer
Aerosol Size Distributions Data ACE-1 project
Reduced and Compiled by NOAA-PMEL
Version 1, 15 November 1996
Tim Bates

Data File contains the following parameters:

JDAY: (decimal)
The data are compiled in 30 minute averages from 15 minutes before to 15
minutes after the half hour.  The time is given as decimal day of year,
Julian Day (JDAY) such that JDAY 32.5 is 12 noon UTC on February 1.

The 30 min averaged data are reported in columns:

D5, D6.3, D8, D10, D12.6, D15.9, D20, D23.9, D28.7, D34.4, D41.3, D49.7,
D60, D72.7, D88.4, D108, D132.9, D164.8, D206.3, D260.8, D334.2, D434.1,
D571.4, D835.46, D897.91, D964.88, D1036.8, D1114.3, D1197.2, D1286.7,
D1382.6, D1485.5, D1596.5, D1715.4, D1843.3, D1981.2, D2129.1, D2287.5,
D2457.9, D2641.3, D2838.7, D3050.5, D3277.9, D3522.7, D3785.6, D4067.9,
D4371.7, D4698, D5048.2, D5424.5, D5829.2, D6264.4.

The numbers following the "D" in the column headers refer to the aerodynamic
diameter of the center of the size bin in nanometers.

The data in the columns are the aerosol size distributions, dN/dlogDp, in
the 52 diameter bins as measured with ultrafine DMA (D5 to D15.9),
TSI DMA (D20 to D571.4) and TSI APS (D835.46 to D6264.4) at the base of the
aerosol sampling mast.  Missing and polluted data values have been
replaced by -99. Units are number per cc in each size bin (cm^-3).
