Hierarchical Processing Scripts

The graphic below shows the structure of the process_all scripts in the ADPAA library. Each script calls the ones beneath it (for example: the process_all_dir script will call the process_all_polcast3 script, which in turn calls the process_all script, and etc.).

Master Processing Scripts

process_all_dir

This simply goes through every PostProcessing directory and processes the *.sea file. Edits are also applied. To view a list of command line arguments that will work with process_all_dir, just enter process_all_dir into the command line.

When running the process_all_dir script it is a requirement to be in the general time period (YYYY) directory. If the script is ran in any other directory nothing will happen.

EX: process_all_dir POLCAST3 

     This simply goes through every PostProcessing directory and processes the *.sea file. Edits are also applied.
     To view a list of command line arguments that will work with process_all_dir, just enter process_all_dir into the command 
     line.

Applications: In order to change the program so that the cloud bases and temperatures could be determined during the 2010 seeding by the Cessna340_N37360 aircraft, it was necessary to find the time intervals that the aircraft was near a target. This is due to the lack of equipment on the aircraft that would allow it to keep track of cloud bases during flight. The process used to determine this post flight is outlined below:

  1. Open the data file for the date in question under /nas/ral/NorthDakota/Summer2010/Aircraft/Cessna340_N37360/FlightData, enter the Post_Processing file, and use cplot to the open the .pol3a or .pol file
  2. Plot Latitude versus Longitude in cplot
  3. Locate the areas that the aircraft seems to circle on the chart
  4. Use a combination of Tools->Select Time Interval and Control->Time Interval in cplot to narrow the flight down to just the circling times of the aircraft. As a rule of thumb, the aircraft must circle a minimum of 15 minutes in order for that region to be considered a target.
  5. Now that you have found the time interval for the target, switch your x and y axis on cplot to Pressure_Alt and Air_Temp respectively. These will produce a rather random plot, but will allow you to find the average cloud height and temperature.
  6. Use Tools-> Statistics to determine the approximate cloud height and temperature.

Single Field Project Scripts

process_all_*

For example, process_all_saudi calls all programs to process aircraft data for the Saudi Arabia 2007 project. You can test a process_all_* by using TestData files, for example: 

 cd /usr/local/ADPAA/src/TestData/FlightData/20140429_152103  && process_all_iphex

Platform Scripts

aimmsprocessing_saudi

Handles and converts all of the AIMMs data that was saved on USB drives to UND Modified NASA format. 

 aimmsprocessing_saudi
 Note: Needs to be executed from a FlightData directory and processes data within the "AIMMSData" directory
       e.g. SaudiArabia/Spring09/Aircraft/KingAir_N825ST/FlightData20090323_114454

Data Level Processing Scripts

AIMMS USB File (*.a?? and *.r??) Scripts

convert_adptonasa

Converts AIMMS adp.out to UND Modified NASA format. 

 convert_adptonasa <inputfile>

Note: The time associated with these files is GPS time. This script currently only converts GPS time to UTC for 2009. For data from any other year make sure that the time offset is correct.

convert_aimmstonasa

Convert AIMMS raw data files (*.aim) created during the Saudi Arabia 2009 project to UND Modified NASA format. 

 convert_aimmstonasa file=inputfile
 Note: inputfile must have the *.aim extension.  This indicates the data file created by the concatenation of all of the *.a?? files.
       Files are assumed to be in the form of ????????.aim.

Note: The *.aim files were created by the concatenation of all the *.a?? files which were saved to the USB drive during flights. For example, cat 03231137.a?? > 03231137.aim

convert_aimtonasa

Converts AIMMs (YY_MM_DD_HH_MM_SS.aim.txt) to UND Modified NASA format. 

 convert_aimtonasa <inputfile>


M300 Data File (*.sea) Scripts

extract_tables

This script will extract the tables in a given *.sea file. The syntax for this is as follows: 

extract_tables <-vm> input_file


getstart_info

This subroutine determines the start time and date from a *.sea file. The syntax for this is: 

getstart_info <-sfm> <-end> <-v> <-vm> input_file


process_raw

Process_raw does Level 1 data processing. The process_raw script takes the *.sea binary file produced by the M300/M200 aircraft acquisition system and creates instrument specific ASCII files. The instrument specific files can have edits applied and be averaged to complete the Level 1 processing. The syntax for process_raw subroutine is using the -h option: 

process_raw -h

Example Syntax 

 process_raw {$ADPAA_DIR}/src/TestData/FlightData/20140429_152103/PostProcessing/14_04_29_15_21_03.sea

Note that debug options (-d -dd -ddd) provide different levels of debug information. The debug options activate (turn on) print statements in the code to provide information as the code is runs. These print statements are helpful when there is an error or issue with the processing of the *.sea file. Helpful for determine what is causing the error.

process_all

Process_all script does data Level 1-4 processing. The process_all script starts with the data acquisition files (for example *.sea M300 data acquisition file) to produced all extracted instrument data files *.raw files) that are contained withing the data acquisition file. The syntax for process_all subroutine is: 

 process_all [options] inputfile

 Options:
   --fast
         Skips long duration processing.
   --final
         The data processing is to produce the final version of the data set
   -h, --help
         Print command syntax and options.
   --L1
         Do not process Level 1 files.
   --L2
         Do not process Level 2 files.
   --L3
         Do not process Level 3 files.
   --logfile
       Creates logfiles in addition to standard data files.

   inputfile - *.sea raw data file or any YY_MM_DD_HH_MM_SS.* based file name.

There should be no errors listed in the created YY_MM_DD_HH_MM_SS.log.postprocessing file upon completion of the process_all job. If there are issues with the processing, the *.log.postprocessing file contains notes where the error occurred. The default is to process files at all data levels, starting with level 1 and processing up to level 4. The --L? options are provided to speed up the data processing by enabling skipping of lower data levels. Typically, once the data has been process once, the --L? can be used to only execute scripts to process higher data files by excluding lower data levels. For example, the --L1 option can be used to exclude level 1 processing, which involves extraction of the data from the data acquisition file. Such lower level data exclusion is useful when testing processing scripts at high data levels where you would want to check the impact on all processing files, which typically includes the generations of the science file(s).

To use the script, use the following syntax:

pcaspscat

The pcaspscat program creates a *.550nm.scat.raw file (from whatever *.conc.pcasp.raw file is in the directory the program is being executed from).

process_raw_file

The process_raw_file program takes the input file and creates a .1Hz file. This utilizes the avgfields function which averages the fields from the source file into a target file. In this case the target file is the newly created .1Hz file. The syntax for this program is as follows:

sfm2hms

Converts time from seconds from midnight (sfm) to hour:minute:second time format

subset

The subset program is used to create a data file which takes data from another file that follows a certain numerical characteristic. For example, say I want all data from the March 20, 2009 Saudi file that had LWC greater than 1 g/cm^3 or all data with temperatures between -10 and -5 degrees Celsius. I can use the subset program to create a file with that data.
