Abstract An empirical model of subauroral polarization stream (SAPS) electric fields has been developed using measurements ion drifts and particle precipitation made by the Defense Meteorological Satellite Program from 1987 to 2012 Dynamics Explorer 2 as functions magnetic local time (MLT), latitude, auroral electrojet index (AE), hemisphere, day year. Over 500,000 passes are used. This is oriented in degree latitude equatorward aurora takes median values instead mean avoid contribution low...
This study compares emergency department (ED) revisits for patients receiving hospital-based substance-use support compared to those who did not receive specialized addiction services at Health Sciences North in Sudbury, Ontario, Canada.
Magnetorotational instability (MRI) is the most promising mechanism behind accretion in low-mass protostellar disks. Here we present first analysis of global structure and evolution non-ideal MRI-driven T-Tauri disks on million-year timescales. We accomplish this a 1+1D simulation by calculating magnetic diffusivities utilizing turbulence activity criteria to determine thermal rate without resorting three-dimensional magnetohydrodynamical (MHD) simulation. Our major findings are as follows....
Abstract A new model of the equatorward boundary diffuse aurora has been developed using observations precipitating particles made by Defense Meteorological Satellite Program (DMSP) from 1987 to 2012 as well Dynamics Explorer 2 (DE 2), which operated August 1981 February 1983. Using a local multilinear regression algorithm, we investigated use different combinations magnetometer indices and solar wind coupling functions with averaging periods weights find best parameterization for aurora. We...
This paper uses energy flux data from the DMSP F6 thru F19 satellites to construct a new equatorward auroral boundary model. method of processing allows one easily extend detections different instrument generations because it is based on standard deviation value instead hard thresholds. Using this method, provides statistics just under 1 million boundaries between 1986 and 2014. These are normal distribution fits for each Kp/Hp MLT bin, which specify an arbitrary percentile. The compares how...
There is a multitude of wave-like phenomena in Earth’s ionosphere and thermosphere such as acoustic waves, gravity planetary tides, Traveling Ionospheric Disturbances (TIDs) which are the ionospheric manifestation atmospheric waves. These often difficult to study since measurements typically irregular time space due geographic constraints for deploying ground instruments natural orbital motion satellites. This frequently precludes Fourier methods Fast Transform (FFT) from being used. The...
