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 
(JDAY) such that JDAY 32.5 is 12 noon GMT 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  Missing and polluted data values have been replaced by 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).
