We present, for the first time, spectral behaviour of aerosol optical depths (AODs) over Manora Peak, Nainital located at an altitude of ∼ 2 km in the Shivalik ranges of central Himalayas. The observations were carried out using a Multi-Wavelength solar Radiometer during January to December 2002. The main results of the study are extremely low AODs during(More)
In this paper, we have made a statistical analysis of solar Hα flares that occurred during the period 1996 to 2005 to investigate their spatial distribution with respect to northern and southern hemispheres of the Sun. The analysis includes a total of 21608 single events. The study shows a significant N−S asymmetry which is persistent with the evolution of(More)
The objective of this thesis is to investigate the reflectance prediction of colored surfaces. Reflectance prediction methods in three different cases were proposed. In the first case, spectra of mixed pigments were simulated as well as spectra of mixing pigments and their concentrations were predicted. In the second case, spectra in multi-angle measurement(More)
