Satellite data

This Telecommunications Handbook aims to tackle the need prior to the concretization of 5G. It is a wellknown fact that systems evolve so fast that literature tends to become outdated at the moment of publication. Nevertheless, the basics of the relevant systems are valid for the long term, and the presentation of the complete set within one book is justified, especially when the information is useful for a variety of professional profiles in order to understand the interdependencies of the systems.

In this paper, the authors used multi-source data, including the electric field data observed by EFM-100C at Rescue Station No. 1 on the “Bai Sau” beach in Vung Tau coastal area for 166 days from May to October 2019; Himawari satellite data and Nha Be weather radar data and the GLD-360 lightning position data to evaluate the lightning warning method. Radar and satellite data were used to determine deep convective clouds. The GLD-360 lightning position data were used to examine the consistency of lightning location with the deep convective clouds.

Ebook "Regional satellite oceanography" addresses the whole range of problems relating to the application of satellite technology to studies of regional seas and sea phenomona - the Gulf Stream, the Kuroshia Current - and coastal zones. It argues that to emphasize global applications is to fail to take into account fundamental idiosyncracies specific to the regional perspective. In addition, it describes implementation techniques - data gathering; in situ data assurance, algorithms for parameter retrieval; data storage; and data output.
