View LAADS DAAC Data
View Data allows users to preview full-resolution images, created from LAADS data products on a web-based map using the GLOBAL Imagery Browse Services (GIBS) tile service, prior to downloading or ordering data sets.
Find LAADS DAAC Data
Interactively search for and download or order data from the LAADS DAAC with Find Data, also known as LAADS Web Search and Order tool. Search by product name, keywords or data characteristics, collection number, date ranges, and geographic area of interest. Download data directly or order data to be optionally post processed and/or staged for download. We support the following post-process operations: subset by dataset name, subset by geographic area of interest or shape, gridding swath data, reprojection to new map projection, mosaic, and reformat to different file formats.
NASA EOSDIS Earthdata Search
Search for and order data from all NASA Earth Observing System missions. Search by product name, keywords, EOSDIS campaign, platform and instrument, date range, and geographic area of interest.
NASA EOSDIS Worldview
Interactively browse global, full-resolution NASA EOS satellite imagery and then download the underlying data. Most of the 100+ available products are updated within three hours of observation, essentially showing the entire Earth as it looks "right now".
USGS Earth Explorer
Provides online, interactive search, browse display, metadata export, and data download for earth science data from the archives of the U.S. Geological Survey (USGS). The USGS Long Term Archive (LTA) at the National Center for Earth Resource Observations and Science (EROS) in Sioux Falls, SD, contains a comprehensive record of the Earth's changing land surface, including:
- Aerial Photography
- Advanced Very High Resolution Radiometer (AVHRR)
- CEOS Legacy
- Commercial Satellites
- Declassified Data
- Digital Elevation
- Digital Line Graphs (DLG)
- Digital Maps
- Earth Observing One (EO-1)
- Global Fiducials
- Global Land Survey (GLS)
- Heat Capacity Mapping Mission (HCMM)
- ISERV
- Land Cover Products
- Landsat Satellite Archives, Characterization, and Legacy Products

AppEEARS
HTTP Interface
All LAADS DAAC products are available at no charge through our download site at https://ladsweb.modaps.eosdis.nasa.gov/archive. The directory structure is as follows:
allData/<collection number>/<product name>/<year>/<day of year>/<file name>
Open Geospatial Consortium (OGC)
The OGC (Open Geospatial Consortium) is an international not for profit organization committed to making quality open standards for the global geospatial community. These standards are made through a consensus process and are freely available for anyone to use to improve sharing of the world's geospatial data.
Web Coverage Service (WCS)
Access data via an application programming interface (API) and the internet by specifying product, geographic, and temporal coverage information.
For the specification, see OpenGIS Web Map Tile Service Implementation Standard.
For information on using a WCS to connect to LAADSWeb and search for and stream back data, see MODAPS Web Coverage Service (WCS) API.
OPeNDAP
The MODIS and VIIRS products in LAADS are available through our OPeNDAP service, which can be accessed at MODAPS Web Coverage Service (WCS) API. The directory structure is identical to that of the web site:
allData/<collection number>/<product name>/<year>/<day of year>/<file name>
OPeNDAP allows data to be downloaded in several formats, such as NetCDF, and allows data to be subset. The following URLs provide examples of how OPeNDAP can be used to download data:
/opendap/RemoteResources/laads/allData/6/MOD03/2013/056/MOD03.A2013056.0000.006.2013056075649.hdf.nc
Download data from day 65, year 2013, ESDT MOD03, and ArchiveSet 6 in NetCDF format.
/opendap/RemoteResources/laads/allData/6/MOD03/2013/056/MOD03.A2013056.0000.006.2013056075649.hdf.ascii
Download data from day 65, year 2013, ESDT MOD03, and ArchiveSet 6 in ASCII format.
/opendap/RemoteResources/laads/allData/6/MOD03/2013/056/MOD03.A2013056.0000.006.2013056075649.hdf.nc?Scan_Offset[0:1:4059][0:1:2707]
Download data from day 65, year 2013, ESDT MOD03, and ArchiveSet 6 in NetCDF format but only include the Scan_Offset variable in a range of 0 to 4059 with a stepping of 1 in the first dimension and a range of 0 to 2707 with a stepping of 1 in the second dimension.
Webification (W10N)
Webification (W10N) is an enabling technology that simplifies the use of data on the web platform. The core idea of Webifcation is to make the inner components of resources directly addressable and accessible via well defined and meaningful URLs.

LAADS Web Service API-V2
API-V2 is a JSON / REST based Application Programming Interface (API) that allows users to search for and download LAADS data products using a programmable interface.
LAADS Web Service (LWS) Classic
LAADS Web Service Classic is a SOAP and REST based Application Programming Interface (API) that allows users to search, order, and download MODIS Level-1 and atmosphere data products through a programmable interface.

- OpenSearch Description Document (XML)
- Dataset OpenSearch Description Document (XML)
NOTE: The API-V2 API is meant to eventually replace the "LWS Classic" API, which will be deprecated in the future.
Full Year Download
A shell script that allows one to download an entire year's worth of data by swapping out values for product, collection, and year.
LAADS Data Download Scripts
Example scripts for batch downloads via a command-line interface (CLI) or other scripting languages such as Shell Script, Perl, and Python.
stage_MODIS.pl
An example perl script that uses SOAP protocol to talk to LAADS Web Service (LWS) Classic. Allows one to search for and download LAADS data from the LAADS HTTP archive tree by product name, collection, date range, and area of interest.
