英文摘要 | We present midlatitude solar response and linear trend from Colorado State University/Utah State University Na lidar nocturnal temperature observations between 1990 and 2017. Along with the nightly mean temperatures (_Ngt), we also use the corresponding 2-hr means centered at midnight (_2MN), resulting in vertical trend profiles similar in shapes as those previously published. The 28-year trend from _Ngt (_2MN) data set starts from a small warming at 85 km, to cooling at 87 (88) km, reaching a maximum of 1.85 +/- 0.53 (1.09 +/- 0.74) at 92 (93) km and turns positive again at 102 (100) km. The 6-month winter trend is much cooler than the 4-month summer trend with comparable solar response varying around 5 +/- 1 K/100 SFU throughout the profile (85-105 km) with higher summer values. We explore the observed summer/winter trend difference in terms of observed gravity wave heat flux heating rate at a nearby station and the long-term trend of gravity wave variance at a midlatitude. Between 89 and 100 km, the lidar trends are within the error bars of the Leibniz Middle Atmosphere (LIMA) summer trends (1979-2013), which are nearly identical to the lidar-Ngt trend. We address the need of long data set for reliable analysis on trend, the extent of trend uncertainty due to possible tidal bias, the effect of a Pinatubo/episodic function, and the impact of stratospheric ozone recovery. |
