Short summary
The unique, quarter-century-long Na lidar observations of midlatitude mesopause region temperatures are used to yield a cooling trend starting from an insignificant value of 0.64K/decade at 85km, increasing to a maximum of 2.8K/decade between 91 and 93km, and then decreasing to a warming trend above 103km. The long warming episode observed in the 1990s is found to mirror that of the global surface cooling after the Mt Pinatubo eruption.
