Coordinated Science Campaign Planning for Earth Observing Missions
Abstract— This paper addresses the problem of coordinated Earth science campaign planning, the process of transforming a specification of the objectives of an Earth science campaign into a set of observations for accomplishing the campaign, utilizing diverse sensing resources from a collection of remote sensors. The paper also introduces a software architecture for a system that performs coordi...
متن کاملTau from a 190-day high-precision spectroscopic multisite campaign
Context. Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were targets of spectroscopic asteroseismic observing projects. Aims. We search for solar-like oscillations in the two bright red-giant stars γ Psc and θ1 Tau from time series of ground-based spectroscopy and deter...
متن کاملObserving Strategies for the NICI Campaign to Directly Image Extrasolar Planets
We discuss observing strategy for the Near Infrared Coronagraphic Imager (NICI) on the 8-m Gemini South telescope. NICI combines a number of techniques to attenuate starlight and suppress superspeckles: 1) coronagraphic imaging, 2) dual channel imaging for Spectral Differential Imaging (SDI) and 3) operation in a fixed Cassegrain rotator mode for Angular Differential Imaging (ADI). NICI will be...
متن کاملThe CLIMODe FIeLD CAMPAIGN Observing the Cycle of Convection and Restratification over the Gulf Stream
O ne of the best-known hydrographic features of the midlatitude oceans is “Sub-Tropical Mode Water” (“STMW”), an upper-ocean water mass characterized by homogeneous properties and extending, in wintertime, to a depth of some 400 m. Mode waters were first observed over 130 yr ago by Thomson (1877). Since these pioneering observations, they have been found in all midlatitude gyres and adjacent to...
متن کاملInfrasonic Observations of Meteoroids: Preliminary Results from a Coordinated Optical-radar-infrasound Observing Campaign
Recent observations using the newly installed Elginfield infrasound array in coordination with the Southern Ontario all-sky meteor camera network and Canadian Meteor Orbit Radar (CMOR) has shown that the number of meteors producing infrasound at the Earth’s surface is more frequent than previously thought. These data show the flux of meteoroids capable of producing infrasound at the ground is a...
