This $495,062 project grant from the National Science Foundation Division of Atmospheric and Geospace Sciences, under the Geosciences program (CFDA 47.050), will fund research examining interpretations of the oxygen isotopic composition of Asian cave calcite at abrupt, millennial, and orbital timescales. Specifically, the grantee will further explore the previously constructed 640,000-year high-resolution record of oxygen isotopic composition in Chinese cave calcite affected by the Asian monsoon to better understand the mechanisms causing abrupt, millennial-scale, and orbital-scale changes in Asian monsoon rainfall. Key questions include where across Asia rainfall changes have occurred, the extent sub-tropical jet position has affected east of Tibet rainfall, and whether inferred climate changes north and west of the Tibetan Plateau were caused by winter or summer precipitation changes. Answering these questions aims to provide insight into the mechanisms driving Asian monsoon rainfall variations. The award was granted to the Regents of the University of Minnesota on September 1, 2022 for the period through August 31, 2026.
