I have a dataset of observations in (latitude, longitude, concentration)
format. How do I plot it out and overlap it onto an US map using ncl?
The strength of concentration field (which will be discrete points in
the plot) has to be reflected by a color label bar. I wanted to place
this plot next to a plot of WRF model output for comparison.

I know how to plot the model output, how to read in text file, and do
panel plots, but I can't seem to find anything similar in the webpage
examples which plot observations. Thanks in advance for your reply.
