Partitioning of latent heat flux at a northern peatland

Aquatic Botany, 2007
Abstract The partitioning of latent heat flux ( Q E ) to vascular plant and moss surface components was assessed for a Sphagnum -dominated bog with a hummock–hollow surface having a sparse canopy of low shrubs. Results from porometry and eddy covariance measurements of Q E showed evaporation from the moss surface ranged from greater than 50% of ...

The sensitivity and optimization of the model parameters for the simulation of latent heat flux

2010 Sixth International Conference on Natural Computation, 2010
The land surface model (LSM) is very complex, and its parameters are one of the key sources of model prediction error. In order to improve the ability of the simulation, the study addressed the parameter sensitivity analysis, optimization and its effect on the simulated latent heat fluxes from the Noah LSM.

Effects of dynamic heat fluxes on model climate sensitivity: Meridional sensible and latent heat fluxes

Journal of Geophysical Research: Atmospheres, 1985
We incorporate physically based parameterizations of atmospheric meridional heat fluxes into the climate model of Wang et al. (1984) to study their effects on climate changes caused by increases of CO2 abundance and solar constant variations. The physically based parameterizations calculate both the magnitudes and profiles of the sensible and latent ...

Foliage temperature and latent heat flux of irrigated wheat

Agricultural and Forest Meteorology, 1991
Abstract A series of 42 hourly measurements from a weighing lysimeter of foliage temperature provided a basis from which to evaluate the residual energy balance method for determining latent heat flux which incorporated foliage temperature measurements by an infrared thermometer.

Sensible and latent heat flux estimates in Antarctica

1993
The assumption has been made that the net annual contribution of water by the processes of deposition and sublimation to the Antarctic Ice Sheet is zero. The U.S. Antarctic Program started installing reliable automatic weather stations on the Antarctic Continent in 1980.

Remote sensing of surface sensible and latent heat fluxes

Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002
The potential for radar/lidar remote sensing of the surface sensible and latent heat fluxes is discussed, and some preliminary results are given. The method utilizes a parameterization scheme involving observables measured by radar/lidar in the convective boundary layer. >

Sensible and latent heat flux over natural bog vegetation

1995
Abstract Goudriaan's crop model is tested for its ability to describe the energy balance of a natural bog vegetation. Data used to drive the model were collected during the summer of 1994. Model results were compared with field data obtained by means of the eddy correlation technique.

Latent Heat Flux from Small Sheltered Lakes

Boundary-Layer Meteorology, 1998
The dependency of the latent heat flux on the over-water fetch on lakes surrounded by tall, dense forest was studied by making use of measurements made on two different-sized lakes. The measurements were made during the NOPEX (Northern Hemisphere Climate-Processes Land Surface Experiment) field campaign.

Latent heat flux variability over the tropical Indian Ocean

International Journal of Climatology, 2023
AbstractThe seasonal evolution and interannual variability of latent heat flux (LHF) over the tropical Indian Ocean (TIO) region is examined for the period 1980–2019. The seasonal distribution of LHF is dominated by the winter pattern of each hemisphere in the TIO.

Sensible and Latent Heat Flux Measurements over the Ocean

Journal of Physical Oceanography, 1982
Abstract This papar presents an extensive act of sensible heat (Reynolds flux and dissipation methods) and latent heat (dissipation method) flux measurements from a stable deep water tower and from ships on the deep sea. Operational difficulties associated with ship spray and flow distortion and with sensor calibration, response and contamination are ...
