Extended Data Fig. 1: Upper atmospheric temperature data during seasons covered by this study.

From: Hydrogen escape on Mars dominated by water vapour photolysis above the hygropause

Extended Data Fig. 1

Profiles were derived from Ar measurements by NGIMS during MAVEN deep dips32, while crosses correspond to temperatures at altitudes around 170 km derived from IUVS measurements43. The black profile was chosen for the study for being representative for conditions experienced in the dusty season at intermediate solar zenith angles.
