Continuous-time state space analysis of d18O, d13C, and CO2 in the Cenozoic Era
Mikkel Bennedsen, Eric Hillebrand, Kathrine Larsen +2
We develop a continuous-time state-space framework for the joint reconstruction of three Cenozoic climate proxies, benthic foraminiferal d18O and d13C and atmospheric CO2, from irr…

Continuous-time state-space methods for d18O and d13C in the Cenozoic Era
Mikkel Bennedsen, Eric Hillebrand, Siem Jan Koopman +2
Time series analysis of d18O and d13C from benthic foraminifera for paleoclimatology poses significant challenges. The data span tens of millions of years, with sparse early record…
