Main take home points

Main Take-Home Points

  • If you are in a sparsely populated area, then your station may give the only weather reports for many miles in any direction; there are many gaps of over 100 miles in US.

  • If you are in a densely populated area, then your station may be the only weather station that sees a small scale weather event (like the Baltimore Harbor gust).

  • In all cases, running a weather station is great way to “give back” to your local community.
