Proposal Title: Comprehensive Ionospheric Characterization Within Storm Enhanced Density
Source Regions
ABSTRACT:
The initial phases of geomagnetic disturbances often cause pronounced enhancements of electron density and total
electron content (TEC) at mid and low latitudes. The location of the Arecibo incoherent scatter radar at ” 30 deg
geomagnetic latitude puts it in a prime position to observe the development of enhanced equatorial anomalies and
electric fields in the source region for mid­latitude storm enhanced density. These mechanisms and structures are of
great significance to magnetosphere/ionosphere coupling studies and the equatorial/mid/high latitude storm time
system. Arecibo radar measurements as part of a coordinated multi­instrument observation strategy would
quantify the ion composition, plasma parameters, and inner plasmasphere electric field drivers / plasma transport
as disturbance events progress.
