LAII Alaska Landscape Flux Survey NOAA/ATDD Long-EZ Aircraft Data,
June 1994, August  1995, and June 1996

This data set contains the aircraft portion of the Land Atmosphere Ice
Interaction  (LAII) Alaska Landscape Flux Survey (ALFS). The object of
the effort was to measure  remote sensing variables and 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/nighttime transect flights.

Measured parameters include water vapor, sensible heat, CO2, PAR and
surface  reflectances from the Alaskan North Slope tundra to study the
factors that control  spatial variability of the exchange.  Scalar
flux densities were measured with an  approximate 2-3km resolution.
Additionally, supporting meteorological parameters such  as
temperature, humidity, CO2 and H2O concentration, 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.
