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 ~ deg 30 geomagnetic latitude puts it in a prime position to observe the development of enhanced equatorial anomalies and electric fields in the source region for mid-latitude 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 multi-instrument observation strategy would quantify the ion composition, plasma parameters, and inner plasmasphere electric field drivers / plasma transport as disturbance events progress.
