Software modules used to process and analyze UND citation data are listed below, along with a short description of each command.  To find the syntax of any of the commands type the given command at a shell prompt with a -help option, i.e. "cplot -help".  

alpha_cal
 
  Calibration routine to determine the alpha angle calibration coefficients.

apply_edits

   Applies data edits to *.raw data file to create a *.clean data file.

avgfields
 
    Averages ASCII data files.  Used to create 4Hz or 1Hz data files from high frequency 25 Hz data files.
   
beta_cal

  Calibration routine to determine the beta angle calibration coefficients.

ccn_conc

  Data level 3 processing module to calculate the CCN concentration.

cn_conc

  Data level 3 processing module to calculate the CN concentration.

convert_sbet

  Converts the 200 Hz post processed binary applanix files to a 25 Hz ASCII file in the standard "NASA" format.

cplot

   Data plotting software module.

fssp_corrections

   Data level 3 processing module to take the raw counts in the FSSP channels to calculate the FSSP concentration using the necessary corrections.

hoffset_cal

  Calibration routine to determine the offset between the aircraft heading angle and track angle.

icing

  Data level 3 processing module to calculate the liquid water content and icing rate from the Rosemount icing probe.

king2lwc

  Data level 3 processing module to calculate the liquid water content from King Probe measurements.

king_calib

  Calibration module to use data from Citation flight to determine the King Probe calibration parameters.

mergefields
 
    Combines parameters from two ASCII data files to create a new merged data file.

onedp2counts
 
    Data Level 2 processing module to convert the binary *.1dp file to the *.fssp.counts.4Hz ASCII file.

scale

    Scales ASCII data files by appling on a slope and offset to a field.

setfssp

    Calibration module to determine the channel sizes based on FSSP calibration information.

subset

    Subsets ASCII data files based on a parameter list and/or start and end times.

tdl2humidity

   Data Level 3 processing  module to calculate TDL parameters.

voltage2physical

  Data Level 2 processing module converts raw measured voltages to physical units.  Currently the module processes basic temperature/pressure data and has options to process Applanix and TDL data.

winds_cal

  Calibration routine to determine the pitot nose and pitot wing calibration coefficients.  Uses reverse tracks flight data.

winds_file

  Data Level 3 processing module used to create the "*.wind.txt" and  "*.SBET.winds.txt" data file.
