Conceptual and geographic layout of the study system. Space weather from the sun, such as coronal mass ejections, disturb Earth’s magnetic field, causing the auroras and potentially decreasing the magnetic field’s reliability for migrating birds.

TPD measurement of H2O, CO2, CO, and O2 in the ratio 60:20:10:10, respectively, with a heating rate of 0.5 K min−1 (Gudipati et al. 2023). For CO also the residual signal has been derived, i.e., after subtraction of the contribution by fragmentation of CO2. The experiment also tracked the chamber background species N, a fragment of N2. The two vertical lines separate the three temperature regimes introduced in Table 1. The portions released in the three temperature ranges are listed in Table 3. -- astro-ph.EP
