The Level-1 and Atmosphere Archive & Distribution System (LAADS) Distributed Active Archive Center (DAAC) is located in Goddard Space Flight Center in Greenbelt, Maryland. The discipline domains of the DAAC are Level-1 data and atmospheric science. The LAADS DAAC primarily provides access to global science data products from two major flagship mission instruments: NASA Earth Observing System’s Terra and Aqua Moderate Resolution Imaging Spectroradiometer  (MODIS), and Suomi NPP  (SNPP) and Joint Polar Satellite System  (JPSS)Visible Infrared Imaging Radiometer Suite  (VIIRS).

MODIS Adaptive Processing System

LAADS DAAC receives data processed by MODAPS, archives and distributes MODIS products from both the Terra and Aqua platforms: Level 1 products (calibrated radiances and geolocation) and Level 2 and 3 Atmosphere and Land products.

LAADS DAAC offers three visual browsers of data — global, granule, and tile — to enable users to search and determine the desired data.

LAADS DAAC Provides access to tools such as subsetting, subsampling, reprojecting, and mosaicing.

LAADS DAAC provides access to its data holdings through MODAPS. Data searches may be conducted using product name, temporal window, collection, and spatial coordinates, or may be found and downloaded using the Level 2 and Level 3 browsers. A variety of subsetting and reprojection options are available to the user. Data may also be downloaded directly from the data pool using FTP.
