Reducing correlation sampling error in ensemble Kalman filter data assimilation
Ensemble Kalman filters are widely used for data assimilation in large geophysical models. Good results with affordable ensemble sizes require enhancements to the basic...- publication PDF

Characterization of high‐m ULF wave signatures in GPS TEC data
GPS total electron content (TEC) measurements were used to investigate high-m ultralow frequency (ULF) waves during the recovery phase of a geomagnetic storm. ULF wave signals...- publication PDF
