Polar Pathfinder Sampler (PPSM): TOVS Polar Pathfinder gridded daily and monthly Arctic atmospheric soundings (1979-1998)
Derived from the global TIROS Operational Vertical Sounder (TOVS) data set, the TOVS Polar Pathfinder provides users with gridded daily and monthly arctic atmospheric soundings. Since 1979, TOVS has been a vital tool for weather forecasting, supplying users with information on the vertical distribution of temperature and moisture in the global atmosphere. TOVS has been particularly useful in providing atmospheric soundings over regions where in situ measurements are sparse.
TOVS Polar Pathfinder data were obtained using a modified version of the Improved Initialization Inversion Algorithm to identify geophysical parameters in snow- and ice-covered areas. The data set has been designed to address the particular needs of the polar research community, and includes quantities used to compute surface turbulent fluxes and drive ocean models.
Variables retrieved from satellite observed radiances for this product include atmospheric temperature profiles, water vapor, surface (skin) temperature, total effective cloud fraction, cloud top pressure, cloud top temperature, turning angle between geostrophic wind and surface stress over ice, emissivity, boundary layer stratification and geostrophic drag coefficient.
TOVS data coverage spans July 7, 1979 through December 31, 1996 at a resolution of 100 km. Sample products for four selected dates in 1988 are included on this CD-ROM.
