Continuous measurements of standard meteorological variables using an automatic weather station and intermittent measurements of the surface energy balance, carbon dioxide flux, and momentum flux using Bowen ratio, eddy covariance, and sigma-T instrumentation were made for 13 months at a...
The exchange process in the lower region of a maize canopy is analyzed for two nights. It appears that during calm nights a free convection state develops in the lower region of the canopy. Convective heat is released at the soil's surface and transported directly to the higher portion of the...
Energy exchanges between a bare soil and the atmosphere depend on both soil parameters and meteorological conditions. The present work has been designed to describe the sensible heat partition between soil and the atmosphere, and to develop simple methods for calculating soil heat flux from soil...
During the Washita '92 field experiment, the local surface energy balance was evaluated at four locations in the USDA-ARS Little Washita River Watershed near Chickasha, OK, using the Bowen ratio-energy balance (BREB) approach. For any given day, differences in the partitioning of the available...
The photosynthetically active radiation (PAR), defined as the wavelength band of 0.400 μm to 0.700 μm, represents most of the visible solar radiation. Although the proportion of global irradiance that originates from diffuse sky radiation is higher for PAR than for all solar shortwave...
A catalogue of hemispherical photographs was collected from conifer forest plantations in order to assess light obstruction by tree crowns. The three conifer species of interest were red pine ( Pinus resinosa ), jack pine ( Pinus banksiana Lamb.), and white spruce ( Picea glauca ). A tree...
Visible imagery from geostationary satellites have a long history of providing accurate estimates of surface insolation over large spatial domains and at high horizontal resolution. In 1995, the United States launched its second generation of these geostationary (GOES) satellites, GOES-8 and...
Single Scots pine ( Pinus sylvestris L.) was subjected to elevated temperature (year-round elevation), elevated CO 2 (elevation from April 15 to September 15) and a combination of elevated temperature and CO 2 for three years in open-topped chambers. Using the data obtained from field...
