Research Abstract

本研究は、放射収支精度向上のために、雲の内部構造を含むミクロ・マクロなパラメータを、衛星観測・地上観測の双方から求め、比較検討した。その結果、雲の3次元的な構造が、その光学的厚さの推定精度に大きな違いを与えることを明らかにした。また、SKYNET 沖縄辺戸岬観測施設で行われた集中観測では、これまでの多様な雲・エアロソル計測器材に加え、新たに雲レーダを用いて観測を行った。これによって、レーダによる有効粒径と衛星計測の結果が水雲では比較的良く一致することを示した。しかし、氷晶雲では必ずしも十分でなかった。また、同時計測されたエアロソル散乱係数や雲水量との関係を解析すると、エアロソルの間接効果が認められた。
