rsl_plotsweep_from_radar

This procedure plots the radar image for a sweep.

Syntax

rsl_plotsweep_from_radar, radar [, ELEVATION=value] [, FIELD=string] [, MAXRANGE=value] [, /NEW_WINDOW] [, SWEEP_INDEX=value] [, VOLUME_INDEX=value] [, TITLE=string] [, WINDOWSIZE=value] [, LIKE_FIELD=string] [, ABOUT_FIELD=string] [, /ADVANCE] [, AZIM_REF_DEG=value] [, RANGE_RING_INTERVAL=value] [, CHARSIZE=value]

Inputs

radar A radar structure.

Keyword parameters

ELEVATION Elevation angle of the sweep to be plotted. If omitted, the value of SWEEP_INDEX, if any, is used. If both of these keywords are omitted, the base scan is plotted.
FIELD A string containing the two-character radar field type to select, for example,'DZ'. Default is the first field stored unless VOLUME_INDEX has a value. The function rsl_get_fields can be used to get the field type strings from the radar structure.
ABOUT_FIELD A string containing information about the field which will appear in TITLE. The default field information is simply the field type, such as 'DZ', 'VR', etc.
LIKE_FIELD A string naming the field type whose color table and value scaling is to be used to plot this data. This keyword is needed only if the field type is not one of those recognized by rsl_plotsweep. Recognized field types are DZ, CZ, ZT, VR, SW, DR, ZD, KD, PH, and RH.
MAXRANGE Maximum range to be plotted, in kilometers. Default is 220 km unless the radar site is Kwajalein, in which case it is 200.
NEW_WINDOW If set, a new window is created for plot.
SWEEP_INDEX Sweep index of sweep to be plotted, where zero is the base scan (default). If both ELEVATION and SWEEP_INDEX are given, ELEVATION is used.
TITLE Title to appear above plot. Default is the site name followed by date and time of scan, the field type, and the elevation angle in degrees.
VOLUME_INDEX The index number (0 to nvolumes-1) of volume (field) selected. Default index is 0. If keyword FIELD has a value, its value overrides that of VOLUME_INDEX.
WINDOWSIZE Window size in pixels. WINDOWSIZE may be scalar or a 2 element array. If scalar, this value is used for the x and y lengths. If an array, the first element is the x length, the second the y length. Default is 525.
ADVANCE This keyword is passed to IDL's MAP_SET procedure. When set, and !p.multi is set, IDL advances to the next plot position in a multiple plots window.
AZIM_REF_DEG The interval in degrees at which to draw azimuth reference lines. Default is not to draw azimuth reference lines.
RANGE_RING_INTERVAL The interval between range rings, in kilometers. Default is 50 km. Set this keyword to zero to turn off range ring display.
CHARSIZE IDL graphics keyword used to set the character size for axes titles and annotations. Normal size is 1.0, which is the default.

Examples

Plot the first sweep of the DZ field.
