Title
A quick overview of a new scintillation database
Abstract
This paper explores a new Ka and Q-band dry scintillation database and ancillary meteorological data collected at Aveiro, Portugal in two converging Earth-satellite propagation paths. The measurement equipment, the parameters of both links and the processing procedure of the database are described first. The dependencies of the hourly averaged scintillation standard deviation with respect to several meteorological parameters, measured at the ground level, and with respect to the wet refractive index are analyzed. The diurnal variation of the hourly averaged scintillation standard deviation, on a monthly and yearly basis, is explored. The yearly amplitude distributions, fades and enhancements, are presented and compared against some available models. The scatter plot of the concurrent hourly averaged scintillation standard deviation is analyzed and a frequency scaling factor is tentatively derived.

Ana Pinho was born in November 1995 in Santa Maria da Feira, Portugal. She took a Master's degree in Engineering, Telecommunications and Informatics at the University of Aveiro in 2019 presenting a thesis dedicated to the analysis and modelling of tropospheric scintillation at Ka and Q-band. She now has a scholarship at the Instituto de Telecomunicações-Aveiro Pole to continue the work in scintillation, study some aspects of depolarization in the Ka-band and collaborate in a MEO propagation measurement campaign.
