- 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: 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.
- Type: ESIDescription: Using this service, select data sets from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed and customized through our Application Programming Interface (API). Our API offers users the ability to programmatically request data using temporal and spatial filters as well as applying subsetting, reformatting, and reprojecting. This is valuable when working with big data sets to request just the parameters you need in the format and transformation you want over a specific spatial area or within a specific temporal range. These are the same customization options that are available in Earthdata Search via the Customize data access method for a given data set. The API may also be helpful if you're interested in incorporating data access commands into your analysis or visualization code.Show MoreShow Less
- Type: Web User InterfaceDescription: The ICESat/GLAS Date Conversion Tool includes several options for obtaining information related to laser track start time. To use the tool, use only one of the conversion options at a time. For example, to find time data for Day 236 of Year 2006, use the third option below and fill in the Day of Year and Year fields, and click Convert.
- Type: Web User InterfaceDescription: The ICESat/GLAS Track Conversion Tool provides starting dates and times and related information for a Track for a specified laser period or for all laser periods. Enter the ICESat track number in the Track field, and optionally enter the laser name in the Laser Period field. The default Laser Period is ALL. Click Convert. The resulting Track Conversion Table lists starting dates and time and other related track information.
- 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
