Using Tianwen-1 Differential One-way Range Signals to Probe Corotating Interaction Regions: Case Studies

open access: yesThe Astrophysical Journal, 2023
The study reports the first detection of corotating interaction regions (CIRs) in the solar wind by the differential one-way range (DOR) signals transmitted by Tianwen-1. Differential phase delay is calculated for the DOR signals. Variations of the total
