| Summary: | post nubila phoebus ii The Open/Closed field line Boundary (OCB) is the most important boundary in the magnetospheric system. On the dayside, the equatorward edge of the 6300 Å[OI] cusp aurora can be used as a proxy for the OCB. This work, which is a dissertation for the degree of Philosophiæ Doctor consists of three scientific papers focusing on the latitude of the optical cusp OCB and one paper focusing on polar cap patch generation mechanisms in the vicinity of the OCB. In Paper I we use modeling to demonstrate the variability of the cusp aurora with respect to vertical volume emission rate profiles and horizontal modulation owing to neutral wind. A meridian scanning photometer (MSP) simulator has been developed in order to study the manifestation of the cusp aurora in the MSP data from Svalbard. A method for obtaining the OCB location and finding the correct mapping altitude in order to transform the |
