Otto is working on retrieval uncertainty quantification for OCO-2 and OCO-3, and on Gaussian process emulation of radiative transfer models.
Dr. Lamminpaa got his PhD on Applied Mathematics from University of Helsinki, Finland, while working at the Greenhouse Gases and Satellite Methods research group at the Finnish Meteorological Institute. In his dissertation work, he applied Dimension Reduction and Markov Chain Monte Carlo (MCMC) methods to two remote sensing retrieval problems: the XCO2 retrieval of NASA's Orbiting Carbon Observatory 2 and the CH4 profile retrieval of the Sodankylä, Finland, TCCON station. His current research interests and work include uncertainty quantification, MCMC methods, inverse problems, statistical emulation of computational physics models, and atmospheric greenhouse gas retrievals.
