RISSimulation of Evapotranspiration and Its Response to Plant Water and CO2 Transfer Dynamics
Publisher: American Meteorological Society
Abstract: Evapotranspiration (ET) is controlled by atmospheric demand, plant and soil hydraulic constraints, and the plant physiological activities that determine canopy resistance. This paper introduces a new ET scheme developed ...
Evaluation of Water Stress Impact on the Parameter Values in Stomatal Conductance Models Using Tower Flux Measurement of a Boreal Aspen Forest
Publisher: American Meteorological Society
Abstract: he impact of water stress on plant stomatal conductance (g) has been widely studied but with little consensus as to the processes governing its responses. The photosynthesis-driven stomatal conductance models usually employ ...
Variations of Climate, Surface Energy Budget, and Minimum Snow/Ice Extent over Canadian Arctic Landmass for 2000–16
Publisher: American Meteorological Society
Abstract: AbstractSnow and ice over land are important hydrological resources and sensitive indicators of climate change. The Moderate Resolution Imaging Spectroradiometer (MODIS) dataset at 250-m spatial resolution generated at the ...
Trends in Land Evapotranspiration over Canada for the Period 1960–2000 Based on In Situ Climate Observations and a Land Surface Model
Publisher: American Meteorological Society
Abstract: An assessment of annual trends in actual evapotranspiration (AET) and associated meteorological inputs is performed at 101 locations across Canada with available long-term hourly surface climate observations to determine ...

A Method to Derive the Multispectral Surface Albedo Consistent with MODIS from Historical AVHRR and VGT Satellite Data
Publisher: American Meteorological Society
Abstract: Multispectral surface albedo and bidirectional properties are required for accurate determination of the surface and atmosphere solar radiation budget. A method is developed here to obtain time series of these surface ...

Modeling the Response of Canopy Stomatal Conductance to Humidity
Publisher: American Meteorological Society
Abstract: Humidity of air is a key environmental variable in controlling the stomatal conductance (g) of plant leaves. The stomatal conductance?humidity relationships employed in the Ball?Woodrow?Berry (BWB) model and the Leuning ...
Comparing Evapotranspiration from Eddy Covariance Measurements, Water Budgets, Remote Sensing, and Land Surface Models over Canada
Publisher: American Meteorological Society
Abstract: his study compares six evapotranspiration ET products for Canada?s landmass, namely, eddy covariance EC measurements; surface water budget ET; remote sensing ET from MODIS; and land surface model (LSM) ET from the Community ...
