Short summary
The study utilized a stratospheric balloon over Natal, Brazil, to investigate the atmospheric response to the 14 October 2023 annular solar eclipse near sunset. Measurements included temperature, pressure, relative humidity and ozone. Significant changes in these parameters were found at different altitudes. These complex changes confirm the importance of the annular eclipses as a driver of localized atmospheric dynamics.
