Summary
Abstract The low‐Earth orbit Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS) instruments, spanning 1995–2023, have spatiotemporal patterns within their metadata that are consistent with the South Atlantic Anomaly (SAA). While the SAA had a known influence on these instruments, this study details new variability and impacts. A large volume of radiation‐triggered events can cause the First‐In First‐Out (FIFO) buffer overflow to occur, which temporarily “blinded” LIS and OTD. Patterns of FIFO and the instrument status flags displayed an evolving intensity and areal extent of SAA interference, affecting climatological view‐time records. The interference had a strong relationship to the sunspot number with Pearson correlation values of −0.50 and −0.48 ( p < 0.0001 for bot
