Terra’s five instruments produce 83 core data products which are distributed through the Land Processes Distributed Active Archive Center (LPDAAC), the Atmospheric Science Data Center (ASDC), Ocean Color Web, Level 1 and Atmosphere Archive and Distribution System, and the National Snow and Ice Data Center (NSIDC).
Each data set is specialized and many work in concert with other data products. To understand how remote sensing works many novice users may benefit from acquainting themselves with the Fundamentals of Remote Sensing, a resource from Natural Resource Canada. Data sets are typically available as Hierarchical Data Format (HDF) files and there are a variety of HDF processing software available that allow users to display and browse images and data file information. Many of these software programs are available in the public domain as well as commercially.
The Terra data from each of the five instruments can be accessed through the respective data centers that host data products. These data centers are listed on each instrument data page.
