Radar field of view plots
The fov_plot
function plots the fields of view of SuperDARN radars onto a map. It does not plot any data.
Getting started
fov_plot -x -stereo -coast -fov -st lyr -d 20181001
All of the above flags are necessary to obtain an informative figure:
-x
Display the figure in an X-terminal-stereo
Use a stereographic projection. One alternative is the orthographic projection (\inlinecode{-ortho})-coast
Plot coast outlines-fov
Plot the field of view outline for the radar specified by the \inlinecode{-st} flag-st
Used to specify which radar to plot (3-letter station name, not the numerical ID code). If omitted, the Goose Bay (gbr) radar is plotted by default-d
Read the radar hardware file that was in use on the date YYYYMMDD (if this date is before the radar was operational, the FOV won't be displayed)
Add colour and coordinate grid, output as png
fov_plot -d 20181001 -t 12:00 -rotate \
-st lyr -fov -ffov \
-stereo -grd -latmin 50 \
-coast -fcoast \
-ffovcol FF0077FF -grdcol FF000000 \
-cstcol FF000000 -lndcol 55000000 -seacol 11000000 \

The -rotate
flag rotates the plot so that local noon is at the top of the figure. Since we have specified -t 12:00
, the radar is displayed in its position at 12:00 UT.
Plot fields of view of all radars
The fields of view of all radars in the northern or southern hemisphere can be plotted by making use of the -ofov
('other fields of view') and/or -fofov
('fill other fields of view') options. If you want all the radars shaded the same colour, remove the -st
, -fov
and -ffov
flags.
