General Questions & FAQs
The answer is yes! There are several ways to programmatically access NSIDC data products and metadata using Application Programming Interfaces (APIs). We also provide the ability to access data using an FTP client.
Yes. This code is provided in files called Delivered Algorithm Packages (DAPs), which are available upon special request...
First, the spatial resolution of AMSR/ADEOS-II and AMSR-E/Aqua data doubles the resolution of Scanning Multichannel Microwave Radiometer (SMMR) and Special Sensor Microwave/Imager (SSM/I) data.
This article describes what customizing services are available for AMSR-E data using Earthdata Search.
There are five different levels of AMSR-E data, Level-0 through Level-4.
AMSR-E Slow Rotation Data is a research product distributed by the Japan Aerospace Exploration Agency (JAXA) that have been obtained with a slow rotation of AMSR-E's antenna at 2 rotations per minute (rpm).
What is the difference between smoothed and unsmoothed data in the AE_L2A data set, and how should I use them together?
Each frequency is looking at a different size footprint. Each frequency has its own feedhorn, and is thus susceptible to independent pointing errors. The most important benefit of resampling (or smoothing) is to create a suite of frequencies that are all looking at the same scene.
Why are there holes of data from the Aqua satellite at the North and South Poles, and why are there different sizes in the ascending and descending grids?
The Aqua satellite travels along the dashed line marking the center of a scan. When that center point reaches its maximum latitude, the ascending half orbit (green dots) ends, and a new descending half orbit (orange) starts.
A typical AMSR-E swath width consists of approximately 2000 scans, with 243 pixels per scan for the 6.9 GHz to 36.5 GHz channels, and 486 pixels per scan for the 89.0 GHz channel.

Fortran readers for AMSR-E Level-2B rain data are available upon request. Please contact NSIDC User Services for more information.
Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface. Users have the option to
First, you can open AMSR-E data automatically with ENVI, which handles the HDF-EOS data format by...
To convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. How you install HDF5 depends on your operating system.
AMSR-E sea ice data sets are provided in the Polar Stereographic projection.
The following are instructions on how to import and display AMSR-E Daily Soil Moisture HDF data in ArcGIS. These instructions were tested with ArcGIS 10.0.
Each AE_L2A data file has a time stamp for each scan. The time array is stored as Vdata under the variable name, Time. a) Using the hdp tool, the Time array can be dumped into a text file using the following commands:
The HDF Group has example code for access and visualization of MODIS, GLAS HDF5, AMSR-E, and NISE data in MATLAB, IDL, Python, and NCL.
All data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system, using wget or curl. Basic command line instructions are provided in the article below.
NASA Earthdata Search is a map-based interface where a user can search for Earth science data, filter results based on spatial and temporal constraints, and order data with customizations including re-formatting, re-projecting, and spatial and parameter subsetting.
NASA Worldview is a map interface that allows users to interactively browse imagery, create visualizations, and download the underlying data.
NASA's Global Imagery Browse Services (GIBS) provides up to date, full resolution imagery for selected NSIDC DAAC data sets.
