Responses of the 14 October 2023 annular solar eclipse observed in satellite temperature profiles
Abstract. On 14 October 2023, an annular solar eclipse occurred, in which, the umbra crossed part of the North Pacific, North, Central and South Americas ending over the South Atlantic ocean. On the day of the eclipse the instrument Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) on board the Thermosphere Ionosphere Mesosphere Energetics Dynamics (TIMED) measures temperature profiles in three orbits crossing the área of the abrangency of the eclipse. One of these orbits registered almost simultaneous events to the eclipse path over the Colombia area. Temperature data from 07 to 21 October 2023 were averaged in that region within a grid of 15° × 15° (latitude x longitude) to establish the control profile. Furthermore, comparisons to profiles observed in the days before and after were done to investigate likely instantaneous effects of the atmosphere to passage of this eclipse. The main results were changes in the temperatures producing cooling of 9–45 K in the troposphere, lower mesosphere and mesopause and warming of 7 K in the stratosphere. These results compared favourably to previous temperature observations during other eclipses and confirmed the potential of the SABER instrument to investigate transient events as solar eclipses.
