MESSENGER MASCS/UVVS Observations of Cold Exospheric Calcium
Abstract
Exospheric calcium is primarily ejected by a high energy process on the dawn hemisphere. UVVS data also show a sporadic cold component at low altitudes. Its temperature is consistent with laboratory measurements of photodesorption of calcium sulfide.
