Abstract This paper presents an improved algorithm, based on the D*-parameter, for dust detection over East Asian region using brightness temperature differences (BTDs) between infrared channels of Advanced Himawari Imager (AHI) onboard Himawari-8. The developed algorithm defines a index in form ratio BTDs: BTD 10.4 μm and 12.4 (BTD 10.4–12.4 ) to that 8.6 8.6–10.4 ). To identify with this inde...

An improved algorithm for the generation of gridded window brightness temperatures is presented. The primary data source is the International Satellite Cloud Climatology Project, level B3 data, covering the period from July 1983 to the present. The algorithm takes window brightness, temperatures from multiple satellites, both geostationary and polar orbiting, which have already been navigated a...

Satellite communication systems play an important role in the deployment of a global communication infrastructure, and the increasing demand for frequency bands with large bandwidth availability to satisfy satellite communications applications requirements makes the exploration of higher and higher frequency ranges of a vital importance. In this paper, an introduction to the WAVE (W-Band Analys...

A new satellite-based rainfall monitoring algorithm that integrates the strengths of both low Earth-orbiting (LEO) and geostationary Earth-orbiting (GEO) satellite information has been developed. The Lagrangian Model (LMODEL) algorithm combines a 2D cloud-advection tracking system and a GEO data–driven cloud development and rainfall generation model with procedures to update model parameters an...

1 0-7803-7651-X/03/$17.00 © 2003 IEEE 2 IEEEAC paper #1197, Updated December 10, 2002 Abstract—Proposed satellite constellation networks, based on Geostationary Earth Orbit (GEO) satellites, Medium Earth Orbit (MEO), and Low Earth Orbit (LEO) systems, will be required to transport IP traffic and to provide quality of service (QoS). This paper proposes a new Diffserv-based scheme of IP bandwidth...

There has been growing interest in broadband satellite networks lately. The unique characteristics of satellites such as long propagation delay, limited bandwidth to be shared among many users, and power limitations necessitate the use of appropriate medium access control (MAC) schemes for bandwidth assignment, particularly in applications with bursty traffic. This paper presents a study of MAC...

Most demand assignment TDMA(1) satellite access protocols use centralised-control access schemes rather than distributed ones because their simplicity and robustness usually compensate for the longer allocation delay. Starting from the FODA/IBEA(2) centralisedcontrol protocol, we studied two distributed-control protocols, named DRIFS(3) and FEEDERS(4) respectively, for accessing a geostationary...
