Six chosen Northern hemisphere locations: daily average Aura MLS temperature at the closest latitude bin and within 1/2 track spacing ( ~12 degrees of longitude). Approximate heights are calculated from pressure levels as h= (64.8/4) (3.- log10 Pmb) Km. [The top geopotential height shown is actually ~90 Km, at P= 0.001 hPa, not 97.)
