I really don't understand why BWI is the official reporting station for Baltimore. I get that you don't have as much as an UHI issue but the airport is over 10 miles south if the city. Are there any other major cities that use a location that far away and south no less. You wouldn't want to use the inner harbor for obvious reasons but say a park in North Baltimore and you would get a truer representation especially in marginal events like yesterday's where every mile north you go means something. Aside from the airports NY uses Central Park. If the distance was reversed and let's say they used some location 10 miles due north of downtown that would probably be the Timonium area. Then the average would jump to 24 or so. Then that may be a little to high. You wouldn't use a location that far north so why use one that far south. An area like Roland Park would be a perfect location. Are airports mandatory to be recording stations? I guess thing even out in the long run but it seems most people from the city area received more than 1.6.
