MODIS/Aqua Snow Cover Daily L3 Global 500m SIN Grid V006
This data set contains daily, gridded snow cover and albedo derived from radiance data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Aqua satellite. Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections.

- 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. 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.
- 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 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.
- Type: Downloadable ToolDescription: A Python-based Jupyter Notebook demonstrating how to access and visualize coincident snow data from the NSIDC DAAC across in-situ, airborne, and satellite platforms from NASA's SnowEx, ASO, and MODIS data sets, respectively.
- Type: Web User InterfaceDescription: 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.
- 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.
- Type: Web User InterfaceDescription: A search interface providing users the ability to search amongst all data sets cataloged by NSIDC.
- 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: 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: 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: 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: 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.Show MoreShow Less
