Study Chromaticity of Solar Spectrum


The chromaticity of solar spectrum is studied with the help of a Solar Spectrum Monitor system that can detect individual color in the spectrum. Recent observations done by the detector on the Solar Radiation and the Erath Milieu Experiment suggest that the sun’s visible spectral irradiance changes from May 2009 to September 2012. The data of Earth’s coordinates and environment have been taken since April 2005 after the devastating Tsunami (December, 2004) of India. The bizarre data of zenith angle, azimuth angle, and temperature of the Earth’s atmosphere show their changes of maxima and minima epoch to epoch. The data of solar spectrum monitor have been taking since 2009 and significant transformations of colored ratios ΔRB/W and ΔRR/W per hour are observed among the regions of each solstice between 2009 and 2012. The author advocates that the abrupt vagaries of the Earth’s movements may cause devastating tsunamis, earthquake, volcanic eruption, cyclones and tornadoes in addition of anomalous changes of solar spectral irradiation, humidity, temperature and pressure; those effects may spoil ecological balance and extinct some living species from the soil of the earth.
