Abstract : The annual sums of the various radiation components near Point Barrow, Alaska, in 1965 were 322 kjoules sq cm for global short-wave radiation, 794 kjoules sq cm for atmospheric back radiation, 185 kjoules sq cm for reflected short-wave radiation and 870 kjoules sq cm for terrestrial outgoing radiation. Net total radiation for the year was 22 kjoules sq cm. Monthly averages of albedo varied from 18% for July to 83% for March. The average temperature for the year was -13.0C. The absolute minimum was -44.3C and the absolute maximum 16.4C. The coldest month was February with an average temperature of -33.7C. August was the warmest month with an average temperature of 3.5C. Half-hourly, daily, and monthly radiation values for net total, total global, and global short-wave radiation, daily average cloud cover, albedo values, and ambient air temperature averages and extremes are presented.
