研究分野
大気放射学、雲とエアロゾル、気候変動
研究内容
　　主な専門は大気物理学および大気放射学である。特に雲、エアロゾルの微物理特性とその時空間変動に関する研究、またそれらが大気中の放射過程を通して地球の気候変動に及ぼす影響について研究を行っている。また、大学共同利用機関・総合地球環境学研究所の創設に学術調査官として関わり、２００１年４月の研究所創設後には、過去２０〜３０年の中国を中心とする東アジアを対象に、大気中の温室効果気体、エアロゾルの濃度分布と人間活動の関係解明をテーマとする研究プロジェクト「大気中の物質循環に及ぼす人間活動の影響の解明」（研究費：５年間で約３．６億円）のプロジェクトリーダーをつとめた。
主な研究成果は、次のとおりである。
（１）航空機を用いた太陽放射の観測から、北西太平洋上におけるエアロゾルの成層状態と中国大陸からの土壌粒子の輸送過程を明らかにした。その結果、黄砂現象が見られる春以外の季節でも気象条件によっては日本上空から太平洋の自由対流圏に黄砂粒子が輸送されることを明らかにした。
（２）国立環境研究所との共同研究でレーザーレーダーとスカイラジオメーターによる同時観測から大気中のエアロゾルの成層状態と粒径分布の関係、および複素屈折率を明らかにした。
（３）１９８７〜１９９１年に実施されたＷＣＲＰ（気候変動国際協同研究計画）の「雲と放射に関する航空機観測」に中心メンバーとして参加し、当時世界中で議論されていた雲による太陽放射の異常吸収は雲の不均質性がもたらす見かけ上のものであることを示した。
（４）ＮＯＡＡ／ＡＶＨＲＲ衛星データを用いて雲の光学的厚さ、雲水量と雲粒有効半径を求める方法を確立し、航空機観測の結果を用いてその有効性を検証した。
（５）北大との共同研究で１９９５年〜１９９８年にかけて冬季北極域の雲の微物理特性と放射特性に関する観測を行い、これらの雲の放射特性は、気温と水蒸気量の変動によって支配されていることを明らかにした。
（６）国立環境研究所、地球フロンティアと共同でアジア域における１９８０〜２０００年の燃料消費量と大気中への物質（SO2、NOx、CO、BC、OC、NMVOC、NH3、CH4、N2O、CO2）の排出量を推計した。アジア域における燃料消費量は20年間で倍増し、それに伴って、大気中への物質の排出量も1.2倍(BC)~2.3倍（NOx）に増加していること、特に、中国における増加傾向が著しく、20年間におけるNOx排出量の増加率は約3倍にもなることを示した。
（７）エアロゾルの観測を福江島、奄美大島、沖縄等で実施した結果、全般的に東アジアのエアロゾルはブラックカーボンの割合が多く、光吸収特性が強いことを明らかにした。
（８）衛星データ解析から、東アジアではエアロゾルの間接効果により低層雲の雲粒は小さくなっているが総雲量は減少していることを明らかにした。
（９）中国の研究者との共同研究により、ヨーロッパや北米で見られるGlobal Dimming and Brightening（１９９０年頃まで日射量が減少し、その後増加に転じた現象）が中国でも見られること、そしてその大きな要因の一つは人為起源エアロゾルであることを示した。
一言
　地球上にはまだまだ分からないことがたくさんあります。 まずは目標を決めてバリバリと研究を進めて行きましょう。若い人の力が未来を創るのです。
