  35. AS2GT: AMSR-E Swath-to-Grid Toolkit • 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. • 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 Joint AMSR-E Science Team Meeting Amanda Leon - NSIDC DAAC 14-16 July 2008
