Work has included analysis of climate and ocean-climate data, from
both in situ and satellite instruments, analysis of output from climate
models, and development of statistical climate prediction systems. The
sea-surface temperature analyses he developed with Richard Reynolds
provide a widely used set of climate products. The improved merged
ocean and land temperature analysis they developed is the NOAA
analysis used for monitoring historical and modern climate temperature
variations. More recent work at CICS
has focused on satellite-based precipitation variations, including
uncertainty estimates and development of improved analysis methods.
