Of no consequence for data processing Field-of-View effects addressed using orbital data and FOV knowledge is well in-hand Temperature data quality is excellent and agrees well with correlative data NLTE temperature ZM cross section shows clear double mesopause structure Diurnal tide and Quasi 2-day wave signatures present Mesosphere chemical heating present on all days analyzed NO radiances show strong effects due to solar storms large NO changes and major cooling Strong NO VER correlation with Ap index and enhancements align with magnetic coordinates. Evidence of NO descent to upper stratosphere with accompanying ozone loss.
