The radiative regime over both tundra and lake were measured in 1966 at the North Meadow Lake micrometeorology study site near Point Barrow, Alaska. The resulting data are of special interest because 1966 is considered climatologically normal, unlike the previously studied years, 1964 and 1965. Global radiation for 1966 was 324 kjoules per sq cm. Annual radiation totals over tundra and lake were, respectively, 175 and 161 kjoules per sq cm for reflected short-wave radiation, 100 and 101 kjoules per sq cm for net long-wave radiation, and 49 and 62 kjoules per sq cm for net total radiation. The average temperature for the year was -13.5C. The absolute minimum was -45.1C and absolute maximum 13.3C. The coldest month was March and the warmest July, with average temperatures of -31.4C and 2.9C, respectively. Hourly values of global short-wave radiation and net total radiation over tundra and lake are presented, along with daily averages or totals for cloud cover, air temperature, global short-wave radiation, net total radiation, reflected short-wave radiation, net short-wave radiation, and albedo. Monthly and annual sums are also tabulated. (Author)
