The BOREAS AFM-03 team used the NCAR Electra aircraft to make
sounding measurements to study the planetary boundary layer
using in situ and remote-sensing measurements. Measurements were
made of wind speed and direction, air pressure and temperature,
potential temperature, dewpoint, mixing ratio of H2O, CO2
concentration, and ozone concentration. Twenty-five research
missions were flown over the NSA, SSA, and the transect during
BOREAS IFCs 1, 2, and 3 during 1994. All missions had from 4 to
10 soundings through the top of the planetary boundary layer.
This sounding data set contains all of the in situ vertical
profiles through the boundary layer top that were made (with the
exception of "porpoise" maneuvers). Data were recorded in
1-second time intervals.
