SMAP L4 Global 9 km EASE-Grid Surface and Root Zone Soil Moisture Land Model Constants V005
SMAP Level-4 (L4) surface and root zone soil moisture data are provided in three products: * SMAP L4 Global 3-hourly 9 km EASE-Grid Surface and Root Zone Soil Moisture Geophysical Data (SPL4SMGP, DOI: 10.5067/9LNYIYOBNBR5) * SMAP L4 Global 3-hourly 9 km EASE-Grid Surface and Root Zone Soil Moisture Analysis Update (SPL4SMAU, DOI: 10.5067/0D8JT6S27BS9) * SMAP L4 Global 9 km EASE-Grid Surface and Root Zone Soil Moisture Land Model Constants (SPL4SMLM, DOI: 10.5067/5C36BVQZW28K). For each product, SMAP L-band brightness temperature data from descending and ascending half-orbit satellite passes (approximately 6:00 a.m. and 6:00 p.m. local solar time, respectively) are assimilated into a land surface model that is gridded using an Earth-fixed, global cylindrical 9 km Equal-Area Scalable Earth Grid, Version 2.0 (EASE-Grid 2.0) projection.

- Type: ECHO ORDERSDescription: NSIDC_ECS EOSDIS ECHO ORDERS Service Implementation
- Type: ESIDescription: NSIDC_ECS ESI EOSDIS Service Implementation to the HEG Subsetter
- 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. 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.
- Type: NOT PROVIDEDDescription: 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.Show MoreShow Less
- Type: Downloadable ToolDescription: An R package for acquisition and processing of NASA SMAP data.
- Type: Downloadable ToolDescription: 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.
- 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: Downloadable ToolDescription: 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.Show MoreShow Less
