PP41F:
New Perspectives on Past Climates: Progress in Proxy System Modeling, Reconstruction Algorithms, and Uncertainty Quantification Posters


Submit an Abstract to this Session


Session ID#: 52723

Session Description:
Historical climate data and reconstructions of past climate are powerful tools for evaluating climate models used to simulate modern climate and project future changes. Gathering spatiotemporally high-resolution paleoclimate data and connecting them to past changes and the spectra and spatial patterns of past variability is thus a priority. We solicit contributions addressing key challenges in paleoreconstruction:  data retrieval and integration from diverse sources, realistic multivariate, multi-archive proxy system (data) modeling; physical and statistical process modeling; comparison of observations and simulations;  and identification and quantification of systematic errors. This session will provide a platform for transparent, robust progress  in future studies.
