Polar Pathfinder Sampler (PPSM): Polar Pathfinder Products (P-Cube) data cube multi-sensor data at 100km resolution
The P-Cube data set is a 100 km resolution subset of many important variables from three Polar Pathfinder Projects in common projection (Lambert azimuthal equal-area) and common grid (EASE-Grid). For the first time, data sets from multiple sensors measuring the Arctic region are being distributed in a manner that facilitates study of polar processes and interactions between them. A "data cube" of the Polar Pathfinder Products, hence the name "P-Cube," allows users to access variables derived from three satellite sensors and use them together. The common spatial resolution for P-Cube is dictated by the lowest resolution product (TOVS data). The P-Cube allows browsing of the multi-sensor data and exploring the relationships among the variables. For AVHRR and SSM/I data, the user may turn to the full resolution, single instrument Polar Pathfinder data sets for greater details.
A wide range of polar climate research applications is possible using this multi-dimensional suite of variables from AVHRR, TOVS and passive microwave instruments. The prototype version of the P-Cube included on this CD-ROM has a temporal coverage of January 1, 1988 to December 31, 1989, and a spatial coverage poleward of 60 degrees N latitude. Future versions of the P-Cube will have expanded temporal and spatial coverage, as well as additional variables.
The current prototype version of the P-Cube includes the following: atmospheric temperature (10 levels), precipitable water (5 layers), boundary layer stratification parameter, geostrophic drag coefficient, turning angle, and microwave surface emissivity (from TOVS); surface albedo, surface (skin) temperature, solar zenith angle, cloud fraction, standard deviation of surface albedo, and standard deviation of surface temperature (from AVHRR); and total ice concentration, surface type and ice velocity (from AVHRR and SSM/I). From the National Centers for Environmental Prediction (NCEP) surface pressure is provided.
Please note that the P-Cube data set is a prototype for a potential long term data set consisting of integrated Polar Pathfinder Products. At the time of the production of the Polar Pathfinder Sampler CD-ROM, the algorithms for a number of variables are still undergoing development and validation.
