What determines where an ASOS/AWOS station is located? I know the system is mainly airport-based, but there are many airports without them. The density of these stations is very irregular across the USA, and with the exception of the mesonets in the Plains, there seems to be no rhyme nor reason as to where they are placed. There are large surface data holes in places you'd think they would be beneficial (like north Texas and western Kansas).
