HMB Plotting

pbp-hmb-plot is a utility program to plot the resulting HMB product. It accepts one or more NetCDF files and generates a summary plot for each. Various options are available to customize the plot.

Typically, the following options are used:

Option	To indicate
--title	Title for the plot
--latlon	Lat/Lon for solar position calculation
--ylim	Limits for the y-axis
--cmlim	Parameters passed to pcolormesh

For example:

pbp-hmb-plot \
     --title "NOAA Ocean Noise Reference Station NRS11, Cordell Bank National Marine Sanctuary:  37.88°N, 123.44°W" \
     --latlon 37.88 -123.44 \
     --ylim 10 2000 \
     --cmlim 64 108 \
     NRS11_20200101.nc

will generate NRS11_20200101.jpg with the following plot:
