Land-Atmosphere-Ocean Interaction (LAOI)


The Land-Atmosphere-Ocean Interaction (LAOI) Group is directed by Prof. Xubin Zeng.

Vision: Enhanced understanding and prediction of the Earth system.

Mission: To improve the understanding and modeling of land-atmosphere-ocean interface processes in the Earth system by integrating theoretical analysis and modeling with global ground-based, airborne, and satellite observations; and to act as a bridge linking global observation, parameterization, climate modeling, and weather forecasting communities on interface processes.

Research areas: Atmosphere-ocean-land-ice interface processes; Weather and climate modeling; Hydrometeorology; Remote sensing; Nonlinear dynamics; Big data analytics

Research Experience:

  • Over 190 peer-reviewed publications (including invited ones) in the above research areas
  • Over 140 invited presentations and hundreds of contributed talks
  • Development, analysis, and interpretation of remote sensing and in situ data over land, ocean, and sea-ice
  • Development of land model and various parameterizations for weather and climate models
  • Development of theories to understand the climate system
  • Close interdisciplinary collaborations with scientists in hydrology, ecology, geoscience, oceanography, remote sensing, and applied mathematics
  • Acting as a bridge linking measurement technology, in situ and satellite data, and modeling communities

Achievement indicators: One of the good indicators of our research achievements is the wide use of our research products in the world, including the implementation of model parameterizations and value-added global datasets in the NCEP and ECMWF operational models for weather forecasting, in the NCAR Community Earth System Model (CESM) and DOE Energy Exascale Earth System Model (E3SM) for climate studies, in WRF for regional studies, and in other regional and global models.
