Abstract

In this paper an attempt has been made to estimate radiative fluxes of short wave, long wave as well as non-radiative fluxes such as sensible heat flux and the surface soil heat flux during daytime over a bare soil at a tropical station Anand (22°35â²N, 72°55²E, 45.1 m asl), for the dry convective period 13-17 May 1997. The site-specific parameters such as attenuation coefficients, albedo, transmissivity, etc. are obtained with the help of observations during 2-11 May 1997. The results are compared with real time data. Comparison of estimated and observed radiative fluxes showed a good agreement. The root mean square error (rmse) is 3 for incoming solar radiation and 8 for net radiation. The sensible heat flux is in general under-estimated. The surface soil heat flux values estimated by two different methods are fairly close to each other. The surface temperature estimated by Fourier s law for heat conduction shows good agreement with the observed values with rmse 5.
