The Swath Stitcher operation for G3 is used to stitch together multiple files of swath data. The operation takes a series of swaths as an input and creates a single output swath. The output values are the concatenation of the input swaths, in temporal order.
Data in Satellite Swath Format
Input Order Numeration
Output Description: Single concatenated swath
Output Parameters: Same as input
Description of this Operation
- Swath: 1- or 2-dimensional data structure, typically representing an array of measurements distributed along the center pixel of a satellite track.
- Scan line: horizontal dimension of swath
- Vertical level (altitude or pressure): vertical dimension of swath
- Pixel: individual data element of the swath.
- Each input swath is read from its input file.
- The swaths are concantenated into a single long swath, in input order.
- The stitched swath is then written to the output file, along with the corresponding time, longitude, latitude, and (if needed) pressure level data.
- If the data consists of profile data, the profile at each pixel is written out.
Algorithm Details: IDL is used because which array-based operations may be performed easily in that language.
Caveats/Warnings: The vertical and horizontal dimensions for swaths described here are the transpose of the arrangement used in HDF4 files.
Origin/Software: Implemented in IDL.
Other Information: This document currently describes only the mathematical approach used in the computation.
