Image captured by AIRS instrument aboard MODIS satellite on March 4, 2006, daytime. ______ Which regions in the diagram above indicate a cloudy area? Blue Grey Pink None of them; this map does not show clouds. ______ The image above was produced by a single satellite. Which of the following describes this satellite’s orbit? Eccentric orbit Polar orbit Geostationary Low Earth orbit Irregular orbit ______ What explains the fourteen white lens-shaped streaks running north to south? These are areas outside of the satellite’s field of view. These are areas of high cloud coverage. These are areas disrupted by interference from the magnetosphere. These are areas that could not be processed at ground level. These are international non-surveillance areas. ____________ Consider the means by which the satellite detected these data.
