摘要: Instantaneous radiative flux components across different climatic regions of USA were computed using Moderate Resolution Imaging Spectroradiometer (MODIS) land, atmosphere and geo-location products for clear sky pixels, colocated in time space with towers. Satellite derived fluxes validated in-situ SURFRAD tower data the respective sites. Significant positive correlation was observed between simulated especially incoming shortwave (r = 0.94), longwave 0.91) outgoing 0.89) radiation. The root mean square errors (RMSE) 50.7, 10.41, 18.54 33.50 Wm−2 shortwave, respectively their corresponding relative RMSE 0.11, 0.10, 0.06 0.08. D-index modeling efficiency (ME) varied from 0.87 to 0.96 0.61 0.85 respectively, indicated good performance present method. coefficient residual mass (CRM) all yielded values close zero except Based on statistical analysis accumulative score highest rank obtained followed by fluxe. From it can be concluded that model predicted satisfactorily flux.
