• 中文摘要： 本計畫原擬使用時逝照相機，自對向天空之凸面鏡中，拍攝其反照之全天空雲況，加以分析研究。因計畫核定及儀器運交之遲滯，而被迫加以修改。初則利用台北松山機場地面目視觀測之一整年雲資料，研究台北雲量之逐月與逐時變化，及其在各高度出現之次數。繼則嘗試以普通照相機先後加裝廣角鏡頭及魚眼鏡頭拍攝雲況照片。最後儀器到達，予以安裝。改進攝影技術，獲得雲況照片。利用幻燈機、微片閱讀機及放映機詳細研閱所攝雲照，個別敘述，並相互比較。對台北全天空雲況變化有啟發性之認識，並奠定今後繼續深入研究此問題之基礎。
• 英文摘要： It was scheduled to use a time lapsecamera to take all sky cloud pictures overTaipei from a convex mirror facing the skyfor study. However, amendment has been madedue to the delay of the delivery of the equip-ment. One year cloud data of surface obser-vation at Shungshan International Airport, Taipei, Taiwan have been used first to studythe monthly and hourly variations of the cloudamount and the frequencies of cloud atdifferent height. Then, cloud photos weretaken by ordinary camera (Nikon) with wideangle lens and subsquently with fish eye lens．Finally, the equipment was installed as soonas it's arrival. After several technical impro-vements cloud pictures were obtained. Byusing projectors, and microfilm reader, Pict-ures were studied individually and compared.Some instructive findings have been acquiredwhich will be a guide for intensive study inthe following year.
