AMSR-E/AMSR2 Unified L2B Half-Orbit 25 km EASE-Grid Surface Soil Moisture V001
The AMSR-E/AMSR2 Unified Level-2B land product provides a long-term data record by combining AMSR-E and AMSR2 data. This data set includes surface soil moisture estimates derived from L1R brightness temperatures using the Normalized Polarization Difference algorithm (NPD) and the Single Channel Algorithm (SCA) along with ancillary information gridded to the 25 km Equal-Area Scalable Earth Grid (EASE-Grid).

- Type: ECHO ORDERSDescription: NSIDC_ECS EOSDIS ECHO ORDERS Service Implementation
- Type: EGI - No ProcessingDescription: Using this service, 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, or through our Application Programming Interface (API). This API offers you the ability to programmatically order and bulk-download data using temporal and spatial filters without the need to script against NSIDC's data directory structure. This may be valuable if you are interested in incorporating data access commands into your analysis or visualization code.
- Type: NOT PROVIDEDDescription: Our subscription service automatically sends you new data as they are delivered from active NASA satellite missions, either via SCP or HTTPS pull. This service is convenient if you require the latest data for a specific region, but you do not want to actively search and order data files regularly. The service cannot be applied to past data already archived at NSIDC.
- Type: NOT PROVIDEDDescription: NASA's Global Imagery Browse Services (GIBS) are responsive and highly available web services designed to facilitate visual discovery of scientific phenomena, support timely decision making for natural hazards, and make imagery of the planet more accessible to the media and public. Much of the imagery is updated daily, and some products span almost 30 years. Access to GIBS imagery is available through the following standards-based web services and formats: Web Map Tile Service (WMTS), Tiled Web Map Service (TWMS), Web Map Service (WMS), Keyhole Markup Language (KML), and Geospatial Data Abstraction Library (GDAL).
- Type: NOT PROVIDEDDescription: Allows users to download select NSIDC Earth Observing System (EOS) DAAC data directly via HTTPS. Products are available from AMSR, AMSR-E, ASO, Aquarius, HMA, IceBridge, ICESat/GLAS, ICESat-2, MEaSUREs, MODIS, NIMBUS, NISE, Passive Microwave, SnowEx, SMAP and VIIRS.Show MoreShow Less
- Type: Web User InterfaceDescription: An interactive tool that estimates when satellites have passed, or will pass, over an area of the Earth. Users specify latitude and longitude or select a location on the map for which to calculate a 5-day sequence of satellite overpasses.
- Type: Downloadable ToolDescription: HDFView is a visual tool for browsing and editing HDF4 and HDF5 files. Using HDFView, you can view a file hierarchy in a tree structure, create new files, add or delete groups and datasets, view and modify the content of a dataset, and add, delete and modify attributes.
- Type: Downloadable ToolDescription: Panoply is a desktop application that interactively plots georeferenced and other arrays encoded in the netCDF, HDF and GRIB file formats. With Panoply you can: Slice and plot geo-referenced latitude-longitude, latitude-vertical, longitude-vertical, time-latitude or time-vertical arrays from larger multidimensional variables; slice and plot "generic" 2D arrays from larger multidimensional variables; slice 1D arrays from larger multidimensional variables and create line plots; combine two geo-referenced arrays in one plot by differencing, summing or averaging; plot lon-lat data on a global or regional map using any of over 100 map projections or make a zonal average line plot; overlay continent outlines or masks on lon-lat map plots; use any of numerous color tables for the scale colorbar, or apply your own custom ACT, CPT, or RGB color table.
- Type: Web User InterfaceDescription: A search interface providing users the ability to search amongst all data sets cataloged by NSIDC.
- Type: Downloadable ToolDescription: A Jupyter notebook exploring data coverage, size, and customization service availability along with direct data download utilizing the NSIDC DAAC's Data Access and Service API.
- Type: Web User InterfaceDescription: NASA Earthdata Search is a map-based interface where users can search for Earth science data, filter results based on spatial and temporal constraints, and when available, order data with customizations including re-formatting, re-projecting, and spatial and parameter subsetting. Thousands of Earth science data sets are accessible from 12 science-oriented Distributed Active Archive Centers (DAACs). The NSIDC DAAC distributes several hundred data sets in NASA Earthdata Search, many with customization options.
- Type: Web User InterfaceDescription: Search and filter data files for a given data set using a map-based interface. Data filtering options include filename wildcard, start and end date, and spatial area as bounding box, polygon, or geospatial file import.Show MoreShow Less
