Command line interface

alcf plot

alcf plot - plot lidar data

Usage: alcf plot <plot_type> <input> <output> [<options>] [<plot_options>]

Arguments:

• plot_type: plot type (see Plot types below)
• input: input filename or directory
• output: output filename or directory
• options: see Options below
• plot_options: Plot type specific options. See Plot options below.

Plot types:

• backscatter: plot backscatter
• backscatter_hist: plot backscatter histogram
• backscatter_sd_hist: plot backscatter standard deviation histogram
• cloud_occurrence: plot cloud occurrence

Options:

• dpi: <value>: Resolution in dots per inch (DPI). Default: 300.
• --grid: plot grid
• height: <value>: Plot height (inches). Default: 5 if plot_type is cloud_occurrence or backscatter_hist else 4.
• subcolumn: <value>: Model subcolumn to plot. Default: 0.
• title: <value>: Plot title.
• width: <value>: Plot width (inches). Default: 5 if plot_type is cloud_occurrence or backscatter_hist else 10.

Plot command options:

• backscatter:
  • --lr: plot lidar ratio (LR)
  • --plot_cloud_mask: plot cloud mask
  • sigma: <value>: Suppress backscatter less than a number of standard deviations from the mean backscatter (real). Default: 3.
  • vlim: { <min> <max }. Value limits (10^6 m-1.sr-1). Default: { 10 2000 }.
  • vlog: <value>: Plot values on logarithmic scale: true of false. Default: true.
• backscatter_hist:
  • vlim: { <min> <max }. Value limits (%) or none for auto. If none and vlog is none, min is set to 1e-3 if less or equal to zero. Default: none.
  • --vlog: use logarithmic scale for values
  • xlim: { <min> <max> }. x axis limits (10^6 m-1.sr-1) or none for automatic. Default: none.
  • zlim: { <min> <max> }. z axis limits (m) or none for automatic. Default: none.
• backscatter_sd_hist:
  • xlim: { <min> <max> }. x axis limits (10^6 m-1.sr-1) or none for automatic. Default: none.
  • zlim: { <min> <max> }. z axis limits (%) or none for automatic. Default: none.
• cloud_occurrence:
  • colors: { <value>... }: Line colors. Default: { #0084c8 #dc0000 #009100 #ffc022 #ba00ff }
  • linestyle: { ... }`: Line style (`solid`, `dashed`, `dotted`). Default: `solid`.
  • labels: { <value>... }: Line labels. Default: none.
  • lw: <value>: Line width. Default: 1.
  • xlim: { <min> <max> }: x axis limits (%). Default: { 0 100 }.
  • zlim: { <min> <max> }: z axis limits (m). Default: { 0 15 }.
