A Multiscale Ensemble Filtering System for Hydrologic Data Assimilation. Part II: Application to Land Surface Modeling with Satellite Rainfall Forcing
Publisher: American Meteorological Society
Abstract: Part I of this series of studies developed procedures to implement the multiscale filtering algorithm for land surface hydrology and performed assimilation experiments with rainfall ensembles from a climate model. However, ...
Data Assimilation for Estimating the Terrestrial Water Budget Using a Constrained Ensemble Kalman Filter
Publisher: American Meteorological Society
Abstract: A procedure is developed to incorporate equality constraints in Kalman filters, including the ensemble Kalman filter (EnKF), and is referred to as the constrained ensemble Kalman filter (CEnKF). The constraint is carried ...
Computation of Potential Flow on S2 Stream Surface for a Transonic Axial-Flow Compressor Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A set of conservative full potential function equations governing the fluid flow along a given S2 streamsurface in a transonic axial compressor rotor was obtained. By the use of artificial ...
Assessment of a High-Resolution Climate Model for Surface Water and Energy Flux Simulations over Global Land: An Intercomparison with Reanalyses
Publisher: American Meteorological Society
Abstract: AbstractLand surface water and energy fluxes from the ensemble mean of the Atmospheric Model Intercomparison Project (AMIP) simulations of a Geophysical Fluid Dynamics Laboratory (GFDL) high-resolution climate model (AM2.5) ...
Evaluation of Subseasonal Drought Forecast Skill over the Coastal Western United States
Publisher: American Meteorological Society
CFSv2-Based Seasonal Hydroclimatic Forecasts over the Conterminous United States
Publisher: American Meteorological Society
Abstract: here is a long history of debate on the usefulness of climate model?based seasonal hydroclimatic forecasts as compared to ensemble streamflow prediction (ESP). In this study, the authors use NCEP's operational forecast ...
A Long-Term Land Surface Hydrologic Fluxes and States Dataset for China
Publisher: American Meteorological Society
Abstract: long-term consistent and comprehensive dataset of land surface hydrologic fluxes and states will greatly benefit the analysis of land surface variables, their changes and interactions, and the assessment of land?atmosphere ...

Publisher: American Meteorological Society
Multisource Estimation of Long-Term Terrestrial Water Budget for Major Global River Basins
Publisher: American Meteorological Society
Abstract: systematic method is proposed to optimally combine estimates of the terrestrial water budget from different data sources and to enforce the water balance constraint using data assimilation techniques. The method is applied ...
A Multiscale Ensemble Filtering System for Hydrologic Data Assimilation. Part I: Implementation and Synthetic Experiment
Publisher: American Meteorological Society
Abstract: The multiscale autoregressive (MAR) framework was introduced in the last decade to process signals that exhibit multiscale features. It provides the method for identifying the multiscale structure in signals and a filtering ...
