35. Joint AMSR-E Science Team Meeting Amanda Leon - NSIDC DAAC14-16 July 2008 35 NSIDC’s Ken Knowles developed AS2GT. 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.AMSR-E 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: AMSR-E Swath-to-Grid Toolkit
