Further, illustrative implementations may involve obtaining the regression relation expression between the surface roughness and the wind strength and then detecting the sea-surface wind, using the information observed by the satellite again. As such, the sea-surface wind information can be obtained through satellite observation, and the information can be utilized for preventive activities against disaster including typhoon, the energy industry including wind power and the fishery in quasi-real time.

Abstract: An automatic observation apparatus of sky climate conditions is provided in which an opening and closing device is designed such that a lid moves upward and downward by an elevator so as to open and close the upper portion of an observer and thus, although it snows in winter, the lid moves upward and downward while maintaining a state in which snow is accumulated on the lid, the snow does not collapse due to movement of the lid and does not fall onto a transparent cover of the observer, and thereby obstruction of a visual field of a camera by snow is prevented.

Abstract: The present invention relates to a method that obtains emissivity or reflectivity based on ratios of the brightness temperature measured by a satellite and the land surface temperature, calculates two reflectivity using polarizing features of a microwave according to surface characteristics, and measures a volumetric soil water content of a land surface considering that water has different physical characteristics from those of soil. In particular, it may be possible to measure volumetric soil water contents on territories of other countries as well as regions which have many limitations and troubles in direct measurement of the volumetric soil water contents. Accordingly, valuable materials in terms of nation economy may be produced together with substantial contribution to industrial fields that have direct effects on agriculture and disaster prevention.
