Output Files

*.serialc.dmtccnc.raw

*.serialh.dmtccnc.raw

dmtccnc2stp (Level 4)

Purpose

Determines the Droplet Measurement Technologies (DMT) Cloud Concentration Nuclei (CCN) Counter concentration at ambient pressure and temperature, and at standard pressure and temperature.

Required Input Files

*.serialc.dmtccnc.raw

*.serialh.dmtccnc.raw

Optional Input Files

*.basic.1Hz (Provides temperature measurement.)

*.physical.1Hz (Provides pressure measurement.)

Note: If physical and basic files not provided, ambient concentration can not be calculated.

Output Files

*.dmtccn_conc.raw

dmtccnc2avg (Level 4)

Purpose

Calculates the CCN concentrations by taking an average of the last 30 seconds of data before switching to a new supersaturation.

Required Input Files

*.dmtccn_conc.raw

Output Files

*.dmtccn_conc_avg.raw

dmtavg2efit (Level 4)

Purpose

The dmtavg2efit idl routines use the 30 sec averages to fit an exponential curve to the supersaturation values.

Required Input Files

*.dmtccn_conc_avg.raw

Output Files

*.dmtccn_ss_efit.raw
