On the interaction between marine boundary layer cellular cloudiness and surface heat fluxes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
The interaction between marine boundary layer cellular cloudiness and surface fluxes of sensible and latent heat is investigated. The investigation focuses on the non-precipitating closed-cell state and the precipitating open-cell state at low ...

Estimation of Sensible and Latent Heat Fluxes Using Flux Variance Method under Unstable Conditions: A Case Study of Tea Plants

open access: yesAtmosphere, 2022
Evapotranspiration is essential for precise irrigation and water resource management. Previous literature suggested that eddy covariance (EC) systems could directly measure evapotranspiration in agricultural fields.

Sensible Heat Fluxes over an Urban Area—Vancouver, B.C. [PDF]

open access: yesJournal of Applied Meteorology, 1974
The use of the eddy correlation technique is demonstrated for the measurement of sensible heat transfer in an urban area. The problems of time and space sampling (in the horizontal and vertical) are investigated. Based on 27 summer days of observations from a roof-top site in the central built-up part of Vancouver, the diurnal variation of sensible ...

Surface-sensible and latent heat fluxes over the Tibetan Plateau from ground measurements, reanalysis, and satellite data [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
Estimations from meteorological stations over the Tibetan Plateau (TP) indicate that since the 1980s the surface-sensible heat flux has been decreasing continuously, and modeling studies suggest that such changes are likely linked to the weakening of the

Upscaling Sensible Heat Fluxes With Area-to-Area Regression Kriging [PDF]

open access: yesIEEE Geoscience and Remote Sensing Letters, 2015
Surface sensible heat flux (SHF) is a critical indicator for understanding heat exchange at the land-atmosphere interface. A common method for estimating regional SHF is to use ground observations with approaches such as eddy correlation (EC) or the use of a large aperture scintillometer (LAS).

Estimation of Sensible Heat Flux and Atmospheric Boundary Layer Height Using an Unmanned Aerial Vehicle

open access: yesAtmosphere, 2019
In this work, sensible heat flux estimated using a bulk transfer method was validated with a three-dimensional ultrasonic anemometer or surface layer scintillometer at various sites.

Spatio-Temporal Trends of Surface Energy Budget in Tibet from Satellite Remote Sensing Observations and Reanalysis Data

open access: yesRemote Sensing, 2021
Being the highest and largest land mass of the earth, the Tibetan Plateau has a strong impact on the Asian climate especially on the Asian monsoon. With high downward solar radiation, the Tibetan Plateau is a climate sensitive region and the main water ...

Estimation of surface energy fluxes under complex terrain of Mt. Qomolangma over the Tibetan Plateau [PDF]

open access: yesHydrology and Earth System Sciences, 2013
Surface solar radiation is an important parameter in surface energy balance models and in estimation of evapotranspiration. This study developed a DEM based radiation model to estimate instantaneous clear sky solar radiation for surface energy balance ...

Evaluation of the Planetary Boundary Layer Height in China Predicted by the CMA-GFS Global Model

open access: yesAtmosphere, 2022
The key role of the planetary boundary layer height (PBLH) in pollution, climate, and model forecasting has long been recognized. However, the observed PBLH has rarely been used to evaluate numerical weather prediction models in China.
