Time resolution = 30 seconds

last revised (V0) = September 2010

Variables:
   Time			seconds		UTC seconds (from REVEAL feed)	
   Day of Year	 			from REVEAL feed
   Altitude		ft		from REVEAL feed
   Ambient Pressure	mb		Static Air Pressure (from REVEAL feed)
   Ambient Temp		K		Static Air Temperature (from REVEAL feed)
   intN			#/cm3		integrated Number Density
   intA			um2/cm3		integrated Surface Area
   intV			um3/cm3		integrated Volume Density
   52 Size Bins		#/cm3		Aerodynamic Binned Concentrations

Data Flags
-999.0 = Data Missing


Notes:	
1. Due to low flow rate, the data is flagged above 28000 ft
2. BinConcentrations are in dN/dlogDp
3. To compute Aerosol Mass, multiply the integrated volume by density (i.e. dust density = 2.2 g/m3)
4. Aerodynamic Bins (in micrometers (um)) =
