TL;DR: In this paper, the authors analyzed potential collision activities among orbiting objects for the next 100 years from the low Earth orbit, medium Earth orbit (MEO), to geosynchronous orbit (GEO) regions.

TL;DR: In this paper, a new risk index based on the Normalized Difference Vegetation Index (NDVI) is defined, in which a static map of fire probability is modulated with the NDVI values to study the dynamic of fire risk over a test area that has been affected by fire in the past years.

TL;DR: In this article, the analysis of the temporal and spatial variations of aerosol and aerosol forcing for major populated and industrial cities in India is presented, where the authors discuss the analysis for the spatial and temporal variation of aerosols and aerosols forcing.

TL;DR: In this article, the authors analyzed the variation of coronal mass ejections during the present solar cycle, including latitude and tilt angle of source regions, position angle of CORONA ejections with respect to their corresponding source regions.

TL;DR: From a large database of ground-based observations the extent of the aurora in corrected geomagnetic coordinates is presented over the duration of the storm event, which showed that the sun and aurora were connected and that auroras generated strong ionospheric currents.

TL;DR: In this paper, the authors used multi-sensor data to study the characteristics of dust storms over the Indo-Gangetic basin and found that these data show characteristic behavior of brightness temperature and Aerosol Index due to dust, which change significantly as dust migrates towards east over Kanpur.

TL;DR: Sawabe et al. as mentioned in this paper used fuzzy Hough transform to detect craters in images with low sun angle, circular features in edge images, curves and circles in thinned and connected edge lines, and discrete or broken circular edge lines.

TL;DR: A review of the available literature to assess the characteristics of the magnetic disturbances and the locations and times of the telegraph effects is presented in this article, which is used to construct a timeline for the whole of the disturbed interval comprising the magnetic storms of August 28/29 and September 2/3.

TL;DR: The Sun Watcher using Active Pixel system detector and image processing (SWAP) is a solar imager in the extreme ultraviolet (EUV) that has been selected to fly in 2007 on the PROBA 2 technological platform, an ESA program as mentioned in this paper.

TL;DR: In this paper, the authors used repeat pass radar images (InSAR) for landslide detection and risk assessment in a mountain village and a mass waste above an alpine traffic route.

TL;DR: In this article, the authors analyzed the urban heat island (UHI) effects on the ten most populated cities of Hungary, including the Budapest agglomeration area, using remotely sensed data.
