The data in the aircraft portion of the Land Atmosphere Ice Interaction (LAII) Alaska Landscape Flux Survey (ALFS) were collected in June 1994, June 1995, August 1995, and June 1996. The object of the effort was to measure remote sensing variables, the vertical flux density of sensible and latent heat, CO2, and momentum for extrapolating surface-based measurements to regional scales. The aircraft operations were conducted from Deadhorse Airport near Prudhoe Bay, Alaska, and consisted of daytime and nighttime transect flights.

The measured parameters included water vapor, sensible heat, CO2, Photosynthetically Active Radiation (PAR), and surface reflectances from the Alaskan North Slope tundra, and were used to study the factors that control spatial variability of the exchange. Scalar flux densities were measured with a resolution of approximately 2-3 km. Supporting meteorological parameters such as temperature, humidity, CO2 and H2O concentrations, wind speed and direction, surface temperature, incoming and net radiation were also observed.

This study was conducted with the National Science Foundation and San Diego State University.
