# Statistical analysis of Curiosity data shows no evidence for a strong seasonal cycle of martian methane

Edward Gillen, Paul B. Rimmer, David C. Catling, 2020. _Icarus 336, 113407_.

Gaussian-process regression of the TLS data reported in 2018 finds the data as a whole not statistically consistent with seasonal variability; the enriched subset alone is equally consistent with stochastic or periodic behaviour.
