.wcm

Multi-Element Water Content System, SEA Model WCM-2000

process_raw (Level 1)

Purpose

Extracts the liquid and total water content along with WCM probe diagnostic data from the SEA M300 data acquisition system file (*.sea). The process_raw script creates the *.seriald0.wcm.raw and *.seriald1.wcm.raw files.

Subroutines

The process_raw script calls the IDL subroutine process_WMI.pro, which in turn calls the subroutine wcm.pro, which then calls the create_wcm_headerd0.pro and create_wcm_headerd1.pro subroutines.

Required Input Files

*.sea

Output Files

Among many other files, it generates:

• *.seriald0.wcm.raw
• *.seriald1.wcm.raw

Syntax

process_raw <-d> <-v> <-vm> input_file

Example Syntax

process_raw ${CoPAS_DIR}/ADTAE/TestData/FlightData/20140429_152103/PostProcessing/14_04_29_15_21_03.sea

wcm2correct.py (Level 3)

Purpose

Calculates the adjusted TWC and LWC (083) for the SEA Water Content Measurement (WCM) probe. Uses the CIP and CDP (PADS/M300) files to determine when in or out of cloud and does a baseline correction when out of cloud for a set duration. Creates a file (*.correct.wcm.raw) with baseline corrected and adjusted water contents.

Required Input Files

*.seriald1.wcm.raw or *.wcm_comb.raw

Optional Input Files'

*.CIP_V.conc.1Hz

*.conc.cdp.1Hz

Output files

*.correct.wcm.raw

Syntax

[python3] wcm2correct.py [verbose=0|1] [cip_conc_file] [cdp_conc_file] wcm_file
