.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

wcm_twc.py (Level2/Level3)

Purpose

Calculates the total water content (TWC) and liquid water contents (LWC) for the SEA Water Content Measurement (WCM) probe from the raw sensing elements' voltage and current data. Uses internal (from WCM) calibration constants. Can use either WCM-supplied static pressure, temperature and true air speed or these data can be provided from external ADPAA files. Data are saved to a *.processed.wcm.raw file. These data are NOT baseline adjusted.

Required Input Files

*.serialc0.wcm.raw

*.seriald0.wcm.raw

*.seriald3.wcm.raw

Optional Input Files

*.basic.1Hz - External air temperature and true air speed data

*.physical.1Hz - External static air pressure data

*.seriald1.wcm.raw - WCM-calculated water content data for comparison with ADPAA-calculated data

Options

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 or *.processed.wcm.raw

Optional Input Files'

*.CIP_V.conc.1Hz

*.conc.cdp.1Hz
