Example on how to plot lake breeze and determine optimal radar pointing direction
=================================================================================

Example workflow on how to run ADAM and plot the resulting lake breeze. In
addition, we will set up an instrument at ATMOS and show the angle at which
the radar should be pointed to optimally capture the lake breeze.
