Systematic Bias in Land Surface Models

Source: Journal of Hydrometeorology:;2007:;Volume( 008 ):;issue: 005:;page 989

Author(s): Abramowitz, Gab; Pitman, Andy; Gupta, Hoshin; Kowalczyk, Eva; Wang, Yingping

Publisher: American Meteorological Society

Abstract: A neural network?based flux correction technique is applied to three land surface models. It is then used to show that the nature of systematic model error in simulations of latent heat, sensible heat, and the net ecosystem ...

Soil Moisture Memory in AGCM Simulations: Analysis of Global Land–Atmosphere Coupling Experiment (GLACE) Data

Source: Journal of Hydrometeorology:;2006:;Volume( 007 ):;issue: 005:;page 1090

Author(s): Seneviratne, Sonia I.; Koster, Randal D.; Guo, Zhichang; Dirmeyer, Paul A.; Kowalczyk, Eva; Lawrence, David; Liu, Ping; Mocko, David; Lu, Cheng-Hsuan; Oleson, Keith W.; Verseghy, Diana

Publisher: American Meteorological Society

Abstract: Soil moisture memory is a key aspect of land?atmosphere interaction and has major implications for seasonal forecasting. Because of a severe lack of soil moisture observations on most continents, existing analyses of ...

Publisher: American Meteorological Society

Abstract: The 12 weather and climate models participating in the Global Land?Atmosphere Coupling Experiment (GLACE) show both a wide variation in the strength of land?atmosphere coupling and some intriguing commonalities. In this ...
