Radar Observations of Near-earth
Much useful information about physical and dynamical properties can be obtained from radar observations of near-Earth asteroids (NEAs) that come within reach of 1 Resolution of echoes in Doppler frequency and/or time groundbased radar telescopes . delay can be used to synthesize 1-D or 2-D images that show a target’s size, shape and rotation. Disc-integrated measurements also have value, becaus...
متن کاملGlobal inundation dynamics inferred from multiple satellite observations , 1993 – 2000
[1] Wetlands and surface waters are recognized to play important roles in climate, hydrologic and biogeochemical cycles, and availability of water resources. Until now, quantitative, global time series of spatial and temporal dynamics of inundation have been unavailable. This study presents the first global estimate of monthly inundated areas for 1993–2000. The data set is derived from a multis...
متن کاملRemote sensing of a near-Earth neutral line during the 5 October 2000 substorm
In this paper we examined the continuous motions of a near-Earth neutral line during the recovery phase of the 5 October 2000 substorm. Estimation was based on the PSBL ion beam model proposed by Onsager (1991) and the Geotail observations. Estimated distances from the Earth ranged from 20 to 60 RE and retreated tailward at velocities of 250 and 300 km/s. This event initiated with the arrival o...

متن کاملDeterminations of Relative Timing of Near-earth Substorm Onset and Tail Reconnection
Several studies have recently been performed that are directed towards determining the timing of near-Earth neutral line (NENL) formation in the tail relative to substorm onset. These studies are reviewed here. It is found that they are all consistent with each other and that they show that NENL formation does not occur prior to substorm onset in the inner plasma sheet. This result is inconsist...
