L3 |
"Spacecraft- and Mission-level" [research-grade] products; resampled spatially and/or temporally and combined with measurements from other MMS instruments to produce a merged data set. A subset of "mission-level" L3 products are provided only for designated events. |

Note: Survey-based Quicklook and Level-1 products are planned to be used for SITL analysis. FPI is planning to produce a SITL-specific product
NOTES from April 9: How to deal with spacecraft-level ... seems to be missing. Roy mentioned that we may need to break L2 into subcategories. Level 2A and 2B.
