N III Bowen Lines and Fluorescence Mechanism in the Symbiotic Star AG Peg [PDF]

Journal of Astronomy and Space Sciences, 2018
We have investigated the intensities and full width at half maximum (FWHM) of the high dispersion spectroscopic N III emission lines of AG Peg, observed with the Hamilton Echelle Spectrograph (HES) in three different epochs at Mt.

Components of near-surface energy balance derived from satellite soundings – Part 2: Noontime latent heat flux [PDF]

Biogeosciences, 2014
This paper introduces a relatively simple method for recovering global fields of latent heat flux. The method focuses on specifying Bowen ratio estimates through exploiting air temperature and vapour pressure measurements obtained from infrared soundings

Understanding the Partitioning of the Available Energy over the Semi-Arid Areas of the Loess Plateau, China

Atmosphere, 2017
To investigate the mechanism of available energy partitioning to sensible and latent heat fluxes over semi-arid regions, data from the Semi-Arid Climate and Environment Observatory of Lanzhou University (SACOL) were analyzed to assess the effects of soil

Energy Distribution Characteristics and Environmental Impact Factors in Different Regions of the Summer Monsoon Transition Zone

Frontiers in Environmental Science, 2022
The summer monsoon transitional zone is a typical transitional ecosystem that is, also ecologically fragile. It is critical to explore the land surface energy balance and the water and heat transfer processes in this region for water resource management.

Evapotranspiration of riparian ecosystems and irrigated cotton agriculture at the middle reaches of the Tarim River, Xinjiang, China

Central Asian Journal of Water Research, 2017
In the steppes, semi-deserts, and deserts of Central Asia the most productive ecosystems are riparian ecosystems like forests and shrublands. Rivers also serve as the water source for irrigation so that the major settlements and oases of the region are ...
