The study was aimed to study influent concentration of total dried sea salt aerosol to decrease solar radiation located in Phetchaburi province by measuring wave-length between 300-1050 nm using spectroradiometer and model MS-700.Spearman,s correlation was used to determine the relationship between the different concentration of sea salt and the measurement of solar radiation. The result showed that decreasing percentage of solar radiation was decreased causing the reflection of radiation from the sun. Moreover high concentration of solar radiation from spectrum between 390-400 nm by small sea salt aerosol and soil particle. Radiation from the sun with wave-length (visible-light 400-700 nm) was increased due to size of soil particle and sea salt aerosol were smaller than the size of the wave-length. Radiation from the sun with wave-length (infrared 700-1040 nm) was increased in both sea salt aerosol and soil particle because the size of sea salt and soil particle were smaller than wave-length .The higher concentration of the sun concentration was in the wave-length between 910-930 nm and wave-length between 955-961 nm both in sea salt aerosol and soil particle. In additionally there should be a reduction of solar radiation in the wave-length between 955-961 nm. Which occurred only in sea salt aerosol due to radiation blocking (Chunkao, 1979) by sea salt particle. Radiation from the sun with wave-length between 1090-1120 nm was decreased the wave-length called atmospheric windrow, the sun radiation can be increased and decreased .Additionally the result showed correlations significant in wave-length 300-311,751-781,911-971 nm and significant high particular in wave-length 1070-1131 nm .respectively.
