NSCAT
  • Project Level 1.7
    An engineering data set containing times, locations, backscatters (so), and attenuation for each beam. Winds are not available. A more detailed description is available on the PO.DAAC's web site.

  • Project Level 2.0
    An operational data set containing (50 km resolution) winds with little engineering information. The four most likely ambiguities are provided, and the selected ambiguity is at the beginning of the array. A more detailed description is available on the PO.DAAC's web site.

  • COAPS/NSCAT Level 2.0
    The NSCAT project's Level 2.0 swath data sets (50 km resolution) are sub-sampled to remove data fields that are less likely to be used (e.g., most of the header, unselected ambiguities, and engineering data). Retained fields are wind speed, wind direction, time, latitude, and longitude. The scatterometer winds are calibrated to a height of 10 m (unchanged from the projects L2.0 data sets). The data sets are also resorted from the original orbit by orbit organization, to daily observations. There is no processing of data. The goal is to provide essential data in a more user-friendly format. The data set should be considered research quality.

  • Project W25
    An operational data set containing (25 km resolution) winds with little engineering information. The four most likely ambiguities are provided, and the selected ambiguity is at the beginning of the array. A more detailed description is available on the PO.DAAC's web site.

  • COAPS/NSCAT W25
    The NSCAT project's W25 swath data sets (25 km resolution) are sub-sampled to remove data fields that are less likely to be used (e.g., most of the header, unselected ambiguities, and engineering data). Retained fields are wind speed, wind direction, time, latitude, and longitude. The scatterometer winds are calibrated to a height of 10 m (unchanged from the projects L2.0 data sets). The data sets are also resorted from the original orbit by orbit organization, to daily observations. There is no processing of data. The goal is to provide essential data in a more user-friendly format. The data set should be considered research quality.

  • COAPS/NSCAT Kinematic Stresses
    The NSCAT project's L1.7 swath data sets are used to calculate kinematic stress magnitudes (25 km resolution). Directions are assumed to be equal to the L2.0 directions. Retained fields are kinematic stress magnitude, stress direction, time, latitude, and longitude. The data sets are also resorted from the original orbit by orbit organization, to daily observations. The data set should be considered research quality. A paper describing the technique for calculating the kinematic stresses (Weissman and Graber, 1999) is in press.

QSCAT

  • COAPS/QuikSCAT Compact Level 2B
    RSS's Level 2B (Ku2001 model function) swath data set (25 km resolution) is sub-sampled to remove data fields that are less likely to be used (e.g., most of the header, unselected ambiguities, and engineering data). Retained fields are wind speed, wind direction, time, latitude, and longitude. The scatterometer winds are calibrated to a height of 10 m. The data sets are also resorted from the original orbit by orbit organization, to daily observations. There is no processing of data. The goal is to provide essential data in a more user-friendly format. The data set should be considered research quality.

  • COAPS/QuikSCAT Stresses
    The QuikSCAT project's L2A and L2B swath data sets are used to calculate stress magnitudes (25 km resolution). Directions are assumed to be equal to the L2B directions. Retained fields are stress magnitude, stress direction, time, latitude, and longitude. The data sets are also resorted from the original orbit by orbit organization, to daily observations. The data set should be considered research quality. These will not be available unit the NSCAT stress algorithm is made applicable to the QuikSCAT data.
