Level 2 2022-04-28 10:30:00.0 0.1 Geophysical properties of the primary Feature of Interest derived from Level 0/1 instrument data by a sequence of computation processes. The spatial extent and time resolution of Level 2 data are usually constrained to those of the source instrument data. Transition to Level 2 commonly includes geolocation of the Feature of Interest and may rely on underlying model assumptions about the feature (such as the slant-to-vertical total electron density transformation or tomography computations). Most commonly, it is the Level 2 resource that the instrument teams release to science community at large for reasoning about the Feature of Interest.
