Mars water vapor abundance from SPICAM IR spectrometer: Seasonal and geographic distributions
The near-IR channel of SPICAM experiment on Mars Express spacecraft is a 800-g acousto-optic tunable filter (AOTF)–based spectrometer operating in the spectral range of 1–1.7 ?m with resolving power of ?2000. It was put aboard as an auxiliary channel dedicated to nadir H2O measurements in the 1.37-?...

This primary scientific goal of the experiment is achieved though successful water vapor retrievals, resulting in spatial and seasonal distributions of H2O. We present the results of H2O retrieval from January 2004 (Ls = 330°) to December 2005 (Ls = 340°), covering the entire Martian year. The seasonal trend of water vapor obtained by SPICAM IR is consistent with TES results and reveals disagreement with MAWD results related to south pole maximum.
