SMAP Enhanced L3 Radiometer Global Daily 9 km EASE-Grid Soil Moisture V004

This enhanced Level-3 (L3) soil moisture product provides a composite of daily estimates of global land surface conditions retrieved by the Soil Moisture Active Passive (SMAP) radiometer. This product is a daily composite of SMAP Level-2 (L2) soil moisture which is derived from SMAP Level-1C (L1C) interpolated brightness temperatures. Backus-Gilbert optimal interpolation techniques are used to extract information from SMAP antenna temperatures and convert them to brightness temperatures, which are posted to the 9 km Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0) in a global cylindrical projection.

NSIDC_ECS_ECHO_ORDERS View Service Record
Type: ECHO ORDERS
Description: NSIDC_ECS EOSDIS ECHO ORDERS Service Implementation
NSIDC_ECS_EGI_API_NO_PROCESSING View Service Record
Type: EGI - No Processing
Description: 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.
NSIDC_ECS_HEG View Service Record
Type: ESI
Description: NSIDC_ECS ESI EOSDIS Service Implementation to the HEG Subsetter
NSIDC_ECS_S4S View Service Record
Type: NOT PROVIDED
Description: Our subscription service automatically sends you new data as they are delivered from active NASA satellite missions. 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. Advanced customization services including reformatting, reprojection, and subsetting are also available with your subscription.
NSIDC_ECS_OPeNDAP View Service Record
Type: NOT PROVIDED
Description: OPeNDAP, the Open-source Project for a Network Data Access Protocol, is a NASA community standard DAP that provides a simple way for researchers to access and work with data over the internet. OPeNDAP's client/server software allows users to subset and reformat data using an internet browser, command line interface, or custom user interface such as a C NetCDF or Java NetCDF-compliant data analysis program.
NSIDC_ECS_GIBS View Service Record
Type: NOT PROVIDED
Description: 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).

NSIDC_ECS_WORLDVIEW View Tool Record
Type: Web User Interface
Description: This application allows you to interactively browse global satellite imagery within hours of it being acquired. You can also save it, share it, and download the underlying data.
NSIDC_ECS_APPEEARS View Tool Record
Type: Web User Interface
Description: The Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) enables users to subset geospatial datasets using spatial, temporal, and band/layer parameters. Two types of sample requests are available: point samples and area samples. Interactive visualizations with summary statistics are provided for each sample within the application, which allow users to preview and interact with their samples before downloading their data.
NSIDC_ECS_SMAPR View Tool Record
Type: Downloadable Tool
Description: An R package for acquisition and processing of NASA SMAP data.
NSIDC_ECS_NASA_LaRC View Tool Record
Type: Web User Interface
Description: 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.
NSIDC_ECS_PODPAC View Tool Record
Type: Downloadable Tool
Description: PODPAC is a python library that builds on the scientific python ecosystem to enable simple, reproducible geospatial analyses that run locally or in the cloud. PODPAC can facilitate accessing, subsetting, projecting, interpolating, analyzing, and combining data products.
NSIDC_ECS_HDFView View Tool Record
Type: Downloadable Tool
Description: 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.
NSIDC_ECS_Panoply View Tool Record
Type: Downloadable Tool
Description: 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.
NSIDC_ECS_EASE_Tools View Tool Record
Type: Downloadable Tool
Description: NSIDC provides software and data files for geolocating EASE-Grid data sets at NSIDC. The geolocation software are contains routines in IDL, FORTRAN and C for converting between latitudes/longitude coordinates and row/column coordinates for both EASE-Grid and EASE-Grid 2.0. The geolocation data files are Look-up files that contain arrays with the latitude and longitude at the center of each EASE-Grid and EASE-Grid 2.0 grid cell.
