Global land-surface evaporation estimated from satellite-based observations
Global land-surface satellite-based observations evaporation estimated
2011/3/14
This paper outlines a new strategy to derive evaporation from satellite observations. The approach uses a variety of satellite-sensor products to estimate daily evaporation at a global scale and 0.25 ...
A comparison of ASCAT and modelled soil moisture over South Africa，using TOPKAPI in land surface mode
ASCAT modelled soil moisture South Africa TOPKAPI land surface mode
2010/4/7
In this paper we compare two independent soil moisture estimates over South Africa. The first estimate is a Soil Saturation Index (SSI) provided by automated real-time computations of the TOPKAPI hydr...
The Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) for estimation of land surface heat fluxes
Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) estimation land surface heat fluxes
2010/4/7
A Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) is proposed for the estimation of surface heat fluxes using Thermal Infrared (TIR) data over sparsely vegetated surfaces. TSEBPS is ...
An overview of the LOess Plateau mesa region land surface process field EXperiment series (LOPEXs)
LOess Plateau field EXperiment series land surface
2009/7/22
A series of land surface process field experiments were carried out in a mesa region of the Chinese Loess Plateau in each of the years from 2004 to 2008 (acronymized as LOPEX04, LOPEX08, etc.). The g...
A Bayesian approach to estimate sensible and latent heat over vegetated land surface
latent heat land surface Bayesian
2009/7/22
Sensible and latent heat fluxes are often calculated from bulk transfer equations combined with the energy balance. For spatial estimates of these fluxes, a combination of remotely sensed and standard...
Some practical notes on the land surface modeling in the Tibetan Plateau
land surface models land-atmosphere interactions Tibetan Plateau
2009/7/22
The Tibetan Plateau is a key region of land-atmosphere interactions, as it provides an elevated heat source to the middle-troposphere. The Plateau surfaces are typically characterized by alpine meadow...
Estimating spatially distributed monthly evapotranspiration rates by linear transformations of MODIS daytime land surface temperature data
evapotranspiration rates land surface temperature
2009/7/22
Under simplifying conditions catchment-scale vapor pressure at the drying land surface can be calculated as a function of its watershed-representative temperature () by the wet-surface equation (W...
Aggregation effects of surface heterogeneity in land surface processes
Aggregation effects surface heterogeneity land surface processes
2009/5/27
In order to investigate the aggregation effects of surface heterogeneity in land surface processes we have adapted a theory of aggregation. Two strategies have been adopted: 1) Aggregation of radiativ...
Implementing surface parameter aggregation rules in the CCM3 global climate model：regional responses at the land surface
surface parameter aggregation land surface CCM3 global climate model
2009/5/27
The land-surface parameters required as input to a GCM grid box (typically a few degrees) are often set to be those of the dominant vegetation type within the grid box. This paper discusses the use an...
Multi-objective calibration of the land surface scheme TERRA/LM using LITFASS-2003 data

2009/5/18
The turbulent sensible and latent heat fluxes simulated in the operational weather forecast model LM have been checked with data from the field experiment LITFASS 2003 (Lindenberg Inhomogeneous Terrai...
Spatial and temporal patterns of land surface fluxes from remotely sensed surface temperatures within an uncertainty modelling framework
Generalised Likelihood Uncertainty Estimation land surface fluxes surface temperatures
2009/5/18
Characterising the development of evapotranspiration through time is a difficult task, particularly when utilising remote sensing data, because retrieved information is often spatially dense, but temp...

2009/4/13
Global terrestrial snowfall was estimated for 59 years from 1948 to 2006 by applying gauge undercatch correction for snowfall and rainfall based on daily meteorological data and gauge type. Following ...
