Surface energy fluxes in wheat (Triticum aestivum L.) under irrigated ecosystem
Journal of Agrometeorology, 2012 The surface energy fluxes were measured over irrigated wheat during winter season. 2008-09 and 2009-10 sown on first week of November. Study revealed that the net radiation flux (Rn) varied from 420 to 693 was during 2008-09 and 328 to 926 W m-2 during ...

Uncertainty analysis of computational methods for deriving sensible heat flux values from scintillometer measurements [PDF]
Atmospheric Measurement Techniques, 2009 The use of scintillometers to determine sensible heat fluxes is now common in studies of land-atmosphere interactions. The main interest in these instruments is due to their ability to quantify energy distributions at the landscape scale, as they can ...

Summertime elemental mercury exchange of temperate grasslands on an ecosystem-scale [PDF]
, 2008 In order to estimate the air-surface mercury exchange of grasslands in temperate climate regions, fluxes of gaseous elemental mercury (GEM) were measured at two sites in Switzerland and one in Austria during summer 2006.

Meteorologische Zeitschrift, 1994 The correct partitioning of the energy between the sensible and latent heat fluxes at the bare soil and computing its ground temperature is very important in designing the surface scheme for modeling the processes in the land-air exchange. However, using

Recovery of the old nova V840 Ophiuchi: A carbon rich system [PDF]
, 2003 We present optical spectroscopy and multi colour photometry of the old nova V840 Oph. We rediscovered the nova based on its position in the colour--colour diagrams. It stands out as a very blue object with an additional red component.

Estimation of evapotranspiration using Bowen ratio method
IFAC-PapersOnLine, 2018 Abstract Evapotranspiration (ET) or water loss to the atmosphere is one of the most significant parts of the hydrologic cycle, and its estimation is subjected to uncertainties. Therefore, Calculation of the ET is an integral part of agricultural water management in local, regional and global water balance studies.

Modified formula for estimating the Bowen ratio – description of the determination procedure [PDF]
Acta Scientiarum Polonorum. Formatio CircumiectusAim of the study: One way of estimating evapotranspiration is to use the heat balance structure of active surface. Material and methods: The paper shows how to derive a formula estimating the Bowen ratio by using measurement data of heat balance ...

Footprint-weighted tile approach for a spruce forest and a nearby patchy clearing using the ACASA model [PDF]
Biogeosciences, 2018 The ACASA (Advanced Canopy–Atmosphere–Soil Algorithm) model, with a higher-order closure for tall vegetation, has already been successfully tested and validated for homogeneous spruce forests.

Trumpet Initial Data for Boosted Black Holes [PDF]
, 2018 We describe a procedure for constructing initial data for boosted black holes in the moving-punctures approach to numerical relativity that endows the initial time slice from the outset with trumpet geometry within the black hole interiors.
