LAADS Web - Level 1 and Atmosphere Archive and Distribution System

HOME DATA IMAGES TOOLS HELP

Welcome to LAADS Web! LAADS Web is the web interface to the Level 1 and Atmosphere Archive and Distribution System (LAADS). The mission of LAADS is to provide quick and easy access to MODIS Level 1, Atmosphere and Land data products and VIIRS Level 1 and Land data products.

Data
Search, order, and download MODIS Level 1, Atmosphere and Land data products and VIIRS Level 1 and Land data products. Products may also be subset by parameter, area, or band, mosaiced, reprojected, or masked.

Images
Visually browse MODIS Level 1, Atmosphere and Land data products.

Tools
Access tools to use with MODIS Level 1, Atmosphere and Land data products and VIIRS Level 1 and Land data products.

Help
Get help including tutorials and contact information.

MODIS level 2 clouds, aerosols, snow, sea ice, fire, land surface temperature, and land surface reflectance products are available within 2.5 hours of observation at LANCE-MODIS.

Information about the production, archive and distribution of the data products in LAADS can be found at the MODAPS Services website.

Any questions should be directed to MODAPS user support. Contact information can be found on the Contacts page.
