Tools

This page provides a list of various tools that work with AMSR-E data.

Tool
Description
AMSR-E Swath to Grid Toolkit (AS2GT) Use this suite of software tools to subset and grid Level-1B and Level-2A AMSR-E swath data. These tools make it easy to process data into custom grids with any temporal or spatial resolution. AS2GT is not a standalone toolkit, but is part of the NSIDC Passive Microwave Swath Data Tools (PMSDT). When you download the software, you get AS2GT as part of the larger package that will also allow you to work with some forms of SSM/I and SMMR data.
Hierarchical Data Format - Earth Observing System (HDF-EOS) NSIDC created this site to answer common questions about HDF-EOS and to provide simple methods for working with the HDF-EOS format. Tools are provided to convert from HDF-EOS to binary, and to dump HDF metadata into ASCII text. In addition, example code for access and visualization of AMSR-E data in NCL, Matlab, and IDL is provided on the HDF-EOS Comprehensive Examples Web page.
Land Masks AMSR-E land masks incorporated into the 6.25, 12.5, and 25 km resolution sea ice products are available as separate arrays in HDF format at each resolution. The land masks are in a polar stereographic projection.
IDL Code to Grid AE_Land Data AMSR-E/Aqua L2B Surface Soil Moisture, Ancillary Parameter, & QC EASE-Grid data files are stored as point data. The point data corresponds to the global EASE-Grid projection. This simple program grids the soil moisture data and outputs it to either a binary or an ascii file.
HDF-EOS to GeoTiff (HEG) This tool enables data to be reformatted, reprojected, stitched/mosaicked, and subsetted. The data can be subsetted by geographic coordinates (spatial) or by data parameters (band). This tool is also available in the shopping cart area of the Data Pool. Table 2 gives the output formats, projections, and subsetting options available using this tool. Table 3 gives the applicable AMSR-E data products that can be used with this tool.
Reverb Reverb is a Web-based, search-and-order tool that provides a way for users to search for Earth Science data from multiple participating archives. Reverb also allows for parameter and spatial subsetting. Table 3 gives the applicable AMSR-E data products that can be subsetted using Reverb.
