Heat flow in the soil (G) was estimated through its relationship with the net radiation
LI-COR systems measure carbon dioxide and water vapor, while radiometers measure the incoming, outgoing and net radiation
gas-phase]), radiative absorption and emission rate, net radiation
source term (defined as positive for a heat loss) and rate of temperature change induced by radiation ([T.
The net radiation
at the earth's surface is of dominant importance in studies of climate changes.
The application chapters in Wilson and Gallant (2000a) describe several such applications using slope, curvatures, contributing area, topographic wetness index (TWI; also called compound topographic index, CTI), incoming shortwave radiation, net radiation
, Prescott index, stream power index, relative elevation and elevation percentile.
In this study, only net radiation
or balance radiation (Rn), sensible heat flux (H) and latent heat (LE) were considered and analyzed along with rainfall, whose data were collected by a micrometeorological station located within the EEcA.
3b) that temporarily dominated the net surface radiation budget until increased solar radiation took over the net radiation
budget during the daylight hours of 23 January (Fig.
W] = correction of the long-wave net radiation
Theoretically this net radiation
input into the system should give some sort of temperature increase, but it's unknown if that signal could be detected or what the magnitude of it would be," said Grise.
Where, Rn is net radiation
(Watt/m2) Le = latent heat of vaporization (Joule/kg), E = flow of water vapor (Kg/m2s), H = sensible heat flow (Watt/m2), G = soil heat flow (Watt/m2), A = heat storage column (Joule/m2).
This equation expresses the partition of the net radiation
(Rn) between soil heat flux (G), sensible heat flux (H) and latent heat flux (LE), corresponding to evaporation for a bare soil and transpiration for vegetation canopy.
where Rn is the intensity of the net radiation
