The header provides information about processing and calibration coefficients: # File created on: 23 3 6 at: 10 46 59 by: rdnew_LX # startime= 32600 duration=10289000 delay= 2800 (ms) # filtering level= 4 modetype=1 # Time drift corrected - version 23/02/2006 # Corrper=1.65 # nbPartMin= 10 # DTV= 1 # DOF sampling section= 0.1200 (mm2) # Calibration Coeff(5)= # 0.19397E+01 0.34303E+00 -0.25788E-02 0.11746E-04 -0.19536E-07 where: - nbPartMin: minimum number of droplet needed to compute the spectrum. - Corrper : coef to manage the synchonization problem. The following lines are the data in the following order from var (1) to var (45), all integers. var(1) : elapsed time (ms) since the beginning of the section (for example, with a 1 Hz processing, var(1) is incremented by 1000 for each sample). var(2) : Fast FSSP record and bloc at the end of the sample SOME DATA FROM THE BASIC ACQUISITION SYSTEM var(3) : Latitude*1000 (deg) var(4) : Longitude*1000 (deg) var(5) : True air speed*1000 (m/s) var(6) : Altitude*1000 (m) var(7) : Pressure*1000 (mbar) var(8) : Temperature*1000 (C) var(9) : Water Vapor mixing ratio*1000 (g/kg); for ACE2 relative humidity*1000 (%) var(10): Vertical velocity*1000 (m/s) var(11): King-Probe LWC*1000 (used for synchronization) var(12): Air density*1000 (Kg/m3) FAST FSSP DATA var(13): Total droplet rate (s^-1) var(14): Mean pulse duration over all detections (digit) var(15): Droplet rate in DOF (s^-1) var(16): Mean pulse duration for DOF detections (digit) var(17): Coincidence correction*1000 var(18): Droplet concentration (cm^-3) var(19): Integral diameter*1000 (micron x cm^-3) var(20): LWC*1000 (g m^-3) var(21): Reflectivity*1000 (dBz) var(22): Mean diameter*1000 (micron) var(23): Mean volume diameter*1000 (micron) var(24): Effective Diameter*1000 (micron) var(25): latitude var(26): longitude var(27): 5% percentile*1000 (micron) ................. var(45): 95% percentile*1000 (micron)
