First sentence: The McGill Ice Cap is the larger and more northerly of the two main ice caps on Axel Heiberg Island.  It covers an area of about 7250 sq. km. and accounts for almost half the areal ice coverage of the island.  Its meteorological station, Upper Ice I, was situated at 79deg 41minN, 90deg 27minW, about 1530 m. above m.s.l. (from the Introduction)
Description: On Axel Heiberg Island an area was selected for an High Arctic study and during the summers of 1959-1962 various earth scienctists  concentrated on the elucidation of the phenomena presented.  An essential part of the four-year programme was the operation of several weather stations, some of which have been continued for short periods since.  The meteorological observations were made for two main purposes:  1) to assess the local climate, which is considerably different from that of the two rather distant, permanent weather stations, Eureka and Isachsen, and 2) to provide the necessarily detailed basis for a long-term investigation of the complex relationship between glacier and climate.

This report describes a meteorological and glacial-meteorological survey carried out in the summer of 1960 at Upper Ice Station I, a representative site in the accumulation area of the McGill Ice Cap on Axel Heiberg Island.  Analyses of general meteorological, micrometeorological and radiation data were made, and simple climatological comparisons with other areas are shown.  The heat balance study indicates that net radiation supplied about 64 per cent, atmospheric convection of sensible heat 35 per cent, and latent heat 1 per cent of the total heat supplied to the melting snow surface at the station during 320 hours of melt.  It was found that, of the total heat available, 81 per cent was used to melt the snow surface and 19 per cent to heat the underlying layers of snow and ice.   (from the Abstract)
Notes: At head of title: Jacobsen-McGill Arctic Research Expedition, 1959-1962.   Addenda and errata for this report are found on a single, inserted sheet.  Considerable editorial work for this report was carried out by Miss Mary Hummel and the Scientific Leader [Fritz Mueller].  The report's  illustrations were drafted in final form by Mrs. Jean Wolfe from the author's sketches.  This is the second of the meteorological volumes to appear;  it was preceded by a study of the meteorology of an ablation area as represented by Lower Ice Station, situated at 79deg 25minN, 90deg 30minW, 208 m. above m.s.l. on Axel Heiberg Island's White Glacier.  See Research Report, Meteorology No. 1 by R. H. Andrews for an analysis.
