Swarm Electric Field Instrument (EFI) Thermal Ion Imager (TII) Raw and Corrected Imagery and Spectra at Low resolution (TISL)
Thematic areas: Plasma measurements, Space Weather
Applicable missions: Swarm
Applicable spacecraft: Swarm-A, Swarm-B, Swarm-C
Swarm Electric Field Instrument (EFI) Thermal Ion Imager (TII) raw and corrected imagery and column sum spectra products at ligh resolution. Measurements are derived by University of Calgary within the "TII Raw And Corrected Imagery / Spectra" (TRACIS) project. This product represents an official archive of Level 0 TII full images and derived (Level 1B) gain-corrected images and energy and angle-of-arrival count-rate spectra. The low-resolution (LR) product consists of TII full images and derived products at the variable TII full image cadence, which varies from a few seconds to several minutes according to the operation plan for each satellite. Image quality is characterized with respect to various TII imaging anomalies.
