Due to the difficulty in making reliable and timely four‐dimensional observations of atmospheric temperature in the vicinity of the path of the total solar eclipse, direct measurements of temperature changes from the troposphere to the stratosphere during a total solar eclipse still haven't been reported before. In this work we use profiles of temperature measurements from a constellation of the FORMOSAT‐3/COSMIC (FS3/C) LEO satellites to estimate temperature changes during the 22 July 2009 total solar eclipse. The FS3/C data reveals a very important temperature response structure in the vertical. The cooling in the troposphere can be attributed to the reduction in solar heating, which is thermally driven. The warming in the stratosphere, especially for those that occurred between 13 and 23 km altitudes could be dynamically driven, which can be induced by the thermal contraction of the troposphere.
