The National Science Foundation (NSF), supported by the Geospace Facility’s Distributed Arrays of Small Instruments (DASI), funded Dr. Cesar Valladares’ research on DASI Track 2: Low-latitude Ionospheric Sensor Network (LISN) Investigations of Traveling Ionospheric Disturbances (TIDs) and Plasma Irregularities. The nearly $900,000 project seeks to provide the operations and maintenance of the LISN. His research may provide insight into how multi-scale TIDs at low latitudes seed plasma phenomena, such as equatorial plasma bubbles, at mid-latitudes.
