The majority of SOS assets are so-called "datasets". Originally conceived as a video system for showing space-based collections of Earth data, the SOS has grown in its utility. The majority of data that traditionally appears on the SOS screens concerns the Earth, either from near-real-time data

SOS uses many off-the-shelf hardware and software components. A spherical screen covered in ordinary latex paint hangs suspended in the center of the projection space. The screen is inert; it neither moves nor has any electronic parts. Surrounding the screen are four video projectors, with each

A collaborative network has been established by institutions with access to SOS, as well as partners who are developing educational programming and content for these systems. The SOS Users
Collaborative Network is backed by the NOAA Office of Education (OEd) and the NOAA Earth System Research

The carbon fiber sphere is 68 inches (1.7 m) in diameter and weighs under 50 pounds (23 kg). The sphere is attached to the ceiling or suspension structure with a three-point suspension system to hold the sphere in place and reduce lateral movement and blurring.

The system requires high quality, bright, long-duty cycle projectors, rather than smaller portable and consumer models to endure the requirements of 8–10 hours per day, 7 days per week of most public displays.
