Post-flight Data Processing Scripts

process_raw

Purpose

Extracts analog data from SEA M300 data system file (*.sea) and creates the *.analog.raw file. Extracts Cloud Imaging Probes (CIP) housekeeping information from SEA M300 data system file(*.sea).

Required Input File

*.sea

Output File

*.analog.raw

*.housekeeping.cip.raw

Example Syntax

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

analog2physical

Purpose

To convert analog measurements from engineering units (voltages) to physical units (i.e. degree C).

Required Input File

*.analog.*

Output File

*.physical.raw

Syntax

 analog2physical <final> <csh_error> <hotwire_offset> <nohotwireslave> <physical> <ccn> <ballvario> <nevzorov> <TDLflow> input_file

Optional parameters

<final> causes the output data to be tagged Final instead of Preliminary.

<csh_error> causes the error to be returned to the csh calling program.

<nohotwireslave> causes the hot wire probe voltage not to be checked.

<physical> generates a *.physical.raw file.

<ccn> generates a *ccn.raw file.

<ballvario> generates a *balvario.raw file.

<nevzorov> generates a *.nevzorov file.

<TDLflow> generates a *.TDLflow.raw file.

Example Syntax

 analog2physical $ADPAA_DIR/src/TestData/FlightData/20140429_152103/PostProcessing/14_04_29_15_21_03.analog.raw
 

The *.analog.raw file is generated from process_raw.

winds_file

Purpose

Creates a "*winds.raw" file by compiling and running the winds_file idl routines

Required Input Files

*.physical.raw and *.applanix.raw

The *.physical.raw file is generated by running the analog2physical script on the *.analog.raw file created by the process_raw script on an *.sea file. The *applanix.raw file is generated by running the process_raw script on an *.sea file.

Output File

*.winds.raw*

Syntax

 winds_file <final> <csh_error> physical_file applanix_file

Optional Parameters

<final> causes the output data to be tagged Final instead of Preliminary.

<csh_error> causes the error to be returned to the csh calling program instead of occurring in the IDL code.

Example Syntax

 winds_file 14_04_29_15_21_03.physical.raw 14_04_29_15_21_03.applanix.raw
