Mapping of 2D sporadic E structure using high density GPS receivers in South East Asia

Sporadic E (Es) is a cloud of intensified electron concentration that developed at the ionospheric E layer that might interrupt the pathway of radio communication. Despite the abundance of studies on Es have been carried out, equatorial Es was hardly highlighted. This investigation was executed with...

description Sporadic E (Es) is a cloud of intensified electron concentration that developed at the ionospheric E layer that might interrupt the pathway of radio communication.

This investigation was executed with the intent of observing the Es events near equatorial South East Asia (SEA) region. Using well-established methods such as ionosonde and Equatorial Atmosphere Radar that set up at Kototabang, Indonesia, the E layer was simultaneously analysed to identify Es.
