Paper Abstract

Solar irradiance, surface and air temperatures change periodically day by day. Then we measured the surface temperature, air temperature, humidity and wind velocity types of ground object such as concrete, asphalt, soil and grass every hour for one cycle namely 24 hours. The relationship between the diurnal radiative energy form surface/air and diurnal solar irradiance was studied as a function of time. If the phases of them were adjusted to each other, a linear relationship was established between them. The relationship between diurnal radiative energy form surface and that form air were studied. The clear linear relationship was found to hold between them. The values of parameters of the relationship were determined using measured data and compared with the estimated values using the radiation balance model. Finally, we tried to estimate radiative energy from surface/air integrated over a day using Landsat/TM data.
