Interesting inversion on the Monday afternoon sounding from Fairbanks, with four distinct layers evident in the lowest 1000 meters. The inversion right off the surface is not particularly steep (by Fairbanks standard), followed by a nearly isothermal layer between 200 and 400 meters AGL and a shallower isothermal layer between 400 and 550 meters AGL and finally a warming layer above that. Some of this stratification is wind driven, with winds here at Keystone Ridge gradually increasing during the day.
