Abstract: A combination formula for evaporation that uses the surface temperature measured by infrared thermometers as a boundary condition is successfully tested against the evaporation obtained from a detailed energy balance and ...

Abstract: A transistorized, battery-operated integrator suitable for obtaining the time average of fluctuating electrical analogue signals in the field with relative errors of about 0.1 to 0.2 per cent is described. A solid state ...

Abstract: A simple apparatus has been devised which automatically reverses the vertical positions of two pairs of shielded and aspirated wet- and dry-bulb diodes. Analog voltage signals proportional to the dry and wet bulb temperatures ...

Abstract: The time and space variability of global radiation have been studied using data collected from a mesoscale network of integrating pyranometers established in Wisconsin, for the period December 1966 through June 1967. The ...

Abstract: A rugged and stable pressure-sphere anemometer system is described which Provides an accurate measurement of wind velocity and direction within a meter of the ground. The horizontal wind velocity, (u2 + v2)½, agreed very ...

Abstract: The silicon photovoltaic solar cell has made possible the construction of simple pyranometers of reasonable accuracy. Cell response is linear, temperature sensitivity is low, and spectral response does not cause serious ...

Abstract: A three-dimensional pressure-sphere anemometer and fast thermometer system (P.S.A.T.) was used to measure vertical heat flux density in the atmospheric surface layer at 1?4 m above alta fescue and snap beans. Good agreement ...
