    • A-CHAIM: Near-Real-Time Data Assimilation of the High Latitude Ionosphere With a Particle Filter 

      Reid, Ben; Themens, David R.; McCaffrey, A; Jayachandran, P.T.; Johnsen, Magnar Gullikstad; Ulich, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-28)
      The Assimilative Canadian High Arctic Ionospheric Model (A-CHAIM) is an operational ionospheric data assimilation model that provides a 3D representation of the high latitude ionosphere in Near-Real-Time (NRT). A-CHAIM uses low-latency observations of slant Total Electron Content (sTEC) from ground-based Global Navigation Satellite System (GNSS) receivers, ionosondes, and vertical TEC from ...
