Statistical analysis of Curiosity data shows no evidence for a strong seasonal cycle of martian methane
Using Gaussian process regression to analyze the Martian surface methane Tunable Laser Spectrometer (TLS) data reported by Webster et al. (2018), we find that the TLS data, taken as a whole, do not indicate seasonal variability. Enrichment protocol CH4 data are consistent with either stochastic vari...

Summary: | Using Gaussian process regression to analyze the Martian surface methane Tunable Laser Spectrometer (TLS) data reported by Webster et al. (2018), we find that the TLS data, taken as a whole, do not indicate seasonal variability. Enrichment protocol CH4 data are consistent with either stochastic variation or a spread of periods without seasonal preference.
