英文摘要During a total solar eclipse (TSE) on 22 July 2009,atmospheric perturbations were monitored from the surface to thermosphere to understand TSEs impact on the meteorological (temperature,relative humidity,wind speed,and wind direction) and chemical (O_3 and NO_x) parameters around Kadapa (14.28°N,78.42°E),a tropical semi-arid region of India.For this purpose,an experiment was conducted at Yogi Vemana University Campus,Kadapa,India,to measure the temperature,wind speed,wind direction,and concentrations of ozone (O_3),NO,NO_2,and NO_x by using the automatic weather station (AWS) and O_3 analyzer.On the eclipse day (22 July 2009),the surface observations at Kadapa showed a reduction in temperature (about 1.1°C) because of the solar insulation.Comparison of the thermal,dynamical (wind),and chemical parameters on the TSE day with control days [preceding (21 July 2009) and succeeding (23 July 2009) the TSE] illustrated the influence of solar eclipse.During the eclipse period,the O_3 mixing ratio decreased,while NO_2 and NO_x increased;however,NO remained unchanged.In addition,radio occultation (RO) temperature profiles from Constellation Observing System for Meteorology,Ionosphere,and Climate (COSMIC)/Formosat Satellite Mission (FORMOSAT-3) and Thermosphere,Ionosphere,and Mesosphere Energetics and Dynamics (TIMED) satellites were utilized to understand the impact of TSE on dynamics of the middle and upper atmosphere from tropopause to the thermosphere.High vertical resolution COSMIC observations revealed that during the solar eclipse,tropopause was cooler with twin peaks (double tropopause).The lower thermosphere between 110 and 130 km became warmer during the TSE,which might be caused by the dynamical response of the atmosphere in this region to the solar eclipse.The experimental data have provided very fine-scale variations of the atmospheric parameters both in time and height and also constituted a new set of results on TSE for further research.
