AMSR-E Swath to Grid Toolkit (AS2GT)
Entry ID: AS2GT
[ Get Service ]
[ Update this Record ]


Summary
Abstract: The AMSR-E Swath-to-Grid Toolkit (AS2GT) is a suite of software tools to subset and grid Levels 1B and 2A AMSR-E swath data. AS2GT makes it possible to quickly and easily work with the AMSR-E data in ways that may not be available in the Level 3 gridded data sets. This toolkit allows you to process data into custom grids with whatever temporal or spatial resolution you require. AS2GT maintains the highest data quality for your application by giving you control over map projection, number of samples per day, input resolution and interpolation method.

Gridding options in AS2GT include:

Map projection
Resolution and grid dimensions
Resampling method
How to handle overlapping swaths
Subsetting by time or region

AS2GT is a suite of software tools distributed with NSIDC's Passive Microwave Swath Data Tools (PMSDT), shown in the following flow chart. (PMSDT also handles some forms of SSM/I and SMMR data. Please refer to the man pages for the utilities distributed with PMSDT for information.

Access Constraints
Registration is required before you can download AS2GT.
Use Constraints
The following requirements apply to AS2GT and the larger PMSDT package.

- AS2GT runs on Unix and Linux systems.
- Some converters, like hdftogs, get_smmr_tbs, and AMSR_E_L2A_togs, depend on
the Hierarchical Data Format (HDF) version 4 available from NCSA.
- The mapx library available from NSIDC Tools is required to run gsgrid.
- gsgrid stores 2 floating point grids per channel in memory, so you will need
2*Nbands*Width*Height*4 bytes of RAM.
- You´ll need a C compiler and the "make" utility to build it.
- Each AMSR-E L2A half orbit takes up about 80 megabytes of disk space and
there are up to 30 half orbit files per day.
