Effects of needleleaf forest cover on radiation and snowmelt dynamics in the Canadian Rocky Mountains
radiation snowmelt dynamics Canadian Rocky Mountains
2014/4/3
Radiation is the main energy source for snowpack warming and melt in mountain needleleaf forests, and runoff
from these forests is the main contributor to spring river flows in western North America....
Topographic effects on solar radiation distribution in mountainous watersheds and their influence on reference evapotranspiration estimates at watershed scale
solar radiation distribution mountainous watersheds
2010/12/22
Distributed energy and water balance models require time-series surfaces of the climatological variables involved in hydrological processes. Among them, solar radiation constitutes a key variable to ...
EVAPOTRANSPIRATION AND PLANT PRODUCTION DIRECTLY RELATED TO GLOBAL RADIATION
EVAPOTRANSPIRATION PLANT PRODUCTION DIRECTLY GLOBAL RADIATION
2009/10/29
This article is based on the thesis, that when sun radiation is not in cxcess
and advected energy supply can be neglected, then for periods of plant
cover and growth, both evapotranspiration and pla...
Prediction equations for estimating evaporation from bodies of water, often
require values of net radiation. Solar radiation data are usually more accurate
and more readily available than measuremen...
The Relationship between Irrigated Pasture Production and Radiation
Relationship Irrigated Pasture Production Radiation
2009/10/29
Regression analyses showed that the best relationship between solar radiation
and pasture production of an irrigated trial cut on a fortnightly basis over 9
years was P = AR 1 B ~ 2 Cwh ere P was th...
Changes in the Flexural Strength of Ice under Radiation Decay
Flexural Strength Ice under Radiation Decay
2009/10/26
The strength of an ice cover significantly affects the timing and severity of
breakup on northern rivers. During the pre-breakup period, thermal and radiative
warming is known to significantly decre...
A Net Radiation Model for Calculating Daily Snowmelt in Open Environments
Net Radiation Model Daily Snowmelt Open Environments
2009/10/26
Climatological data from three stations in western Canada are used to develop
a model for estimating daily net radiation from station latitude, station altitude
and cloud cover. Expressions describi...
Solar Radiation Estimation using Temperature-based,Stochastic and Artificial Neural Networks Approaches
Solar Radiation Estimation Temperature-based Artificial Neural Networks
2009/10/22
Radiation is a variable that governs many hydrological and phenological
processes, but its measurements are not made routinely. To overcome this problem,
continuous hydrological models that include ...
High-resolution satellite-based cloud-coupled estimates of total downwelling surface radiation for hydrologic modelling applications
total downwelling surface radiative fluxes hydrologic modelling
2009/7/22
A relatively simple satellite-based radiation model yielding high-resolution (in space and time) downwelling longwave and shortwave radiative fluxes at the Earth's surface is presented. The primary a...
Combined modelling of shortwave and thermal radiation for one-imensional SVATs
shortwave one-imensional
2009/3/25
Expressions for the upwelling and downwelling fluxes of optical and thermal radiation between soil, vegetation and the sky are derived, under certain simple assumptions. These are that interception of...
Long-term patterns in dissolved organic carbon in boreal lakes: the role of incident radiation, precipitation, air temperature, southern oscillation and acid deposition
dissolved-organic-carbon lakes climate solar-radiation
2009/3/12
Both lake-specific (e.g. pH) and regional (e.g. precipitation) factors affect DOC concentration and pattern. Using annual DOC concentration in nine boreal lakes in the ice-free season, the potential i...
Solar radiation-nutrient interaction enhances the resource and predation algal control on bacterioplankton: A short-term experimental study
Solar radiation-nutrient predation algal
2014/5/4
An in situ experimental assessment was made of the effects of the interaction between spectral composition of solar radiation and the limiting nutrient (phosphorous, P) on the algae-bacteria link, mea...
