The solar wind particles CoDICE collects and sorts are highly energized particles, called suprathermal particles, which are moving faster (and therefore have higher energy) than the solar wind particles that SWAPI collects. CoDICE also simultaneously measures the velocity, direction of travel, energies, and types of specific species of PUIs from the local interstellar medium, the interstellar material surrounding our solar system found directly outside of the heliosphere. Some of these are hydrogen and helium ions like SWAPI, but CoDICE is also able to collect and analyze heavier ions than SWAPI can. <_Description>Source: Master/CDFglobalAttributes/TEXT Users should acknowledge the sources of data used in all publications, presentations, and reports using an appropriate DOI.
