QuikSCAT Swath Data Documentation

Swath Data Set Documentation

The QuikSCAT project's Level 2B 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.

QuikSCAT Test Data and Read Files

Documentation on test data is included in this file and on the PO.DAAC's QuikSCAT web site.
Contact: "Glenn Shirtliffe" <gms@seastore.jpl.nasa.gov>
This file contains the following files, which are applicable to all levels of data:

1. The rev/time file, REV_TIME.DAT
2. The batch 0004 quality assurance summary file

Then, for each level of data available on the FTP site, information is provided describing the location, filenames, and size of:

1. The batch 0004 data files
2. The batch 0004 'in-line' quality assurance files (if available)
3. C, Fortran, and IDL read software
4. documentation files
