This project will compile a climatological data set of the                      temperature structure of the lower troposphere north of 65 deg N                latitude with particular emphasis on the boundary layer depth and               temperature inversion strength.  Existing temperature soundings                 will be collated to produce a homogeneous arctic-wide data base.                The lower tropospheric temperature inversion that is                            characteristic of the arctic exerts a substantial influence on                  many aspects of coupled arctic air-sea-ice processes by affecting,              for example, the energy and momentum exchange, trace gas and                    pollutant dispersion, ice crystal formation, and boundary layer                 ozone destruction.  Given the fact that climatic models predict                 that trace gas induced warming will be most pronounced in polar                 regions, climate changes may be most easily detectable in secular               changes in the structure of the boundary layer.  An understanding               of the spatial and temporal scales of the arctic boundary layer                 characteristics is central to a number of atmospheric processes.                The primary goal is to establish a single comprehensive data set                from which to develop a representative climatology of arctic                    temperature inversions and boundary layer parameters.  Rawinsonde               data from land stations, ships, and ice islands, as well as                     aircraft dropsonde data will be analyzed to determine spatial and               temporal trends of such parameters as inversion depth, inversion                base, and vertical gradients of wind, temperature, and humidity.
