Global Formulation of the Synthetic Storm Technique Oriented to Satellite Link–Budget Design
Electronics (Switzerland), 2022 We have updated the global Synthetic Storm Technique (referred to as the global SST) by reformulating it according to a larger database of rain rate time series collected in several sites in different climatic regions. For each site, the average annual probability distribution of rain attenuation obtained with the global SST, PSST,gloA, in a slant path,

Application of Synthetic Storm Technique for Diurnal and Seasonal Variation of Slant Path Ka-Band Rain Attenuation Time Series over a Subtropical Location in South Africa [PDF]
International Journal of Antennas and Propagation, 2015 As technology advances and more demands are on satellite services, rain-induced attenuation still creates one of the most damaging effects of the atmosphere on the quality of radio communication signals, especially those operating above 10 GHz.

Subtropical Rain Attenuation Statistics on 12.6 GHz Ku-Band Satellite Link Using Synthetic Storm Technique [PDF]
SAIEE Africa Research Journal, 2018 In this work, measured subtropical rain attenuation was compared with rain attenuation generated theoretically by the Synthetic Storm Technique (SST). The rain attenuation data was obtained from a Ku-band satellite TV link collocated at the site of a rain rate measurement system in Durban, South Africa (28°87'S, 30°98'E). A mathematical model developed

Deriving column-integrated thermospheric temperature with the N2 Lyman–Birge–Hopfield (2,0) band [PDF]
Atmospheric Measurement Techniques, 2021 This paper presents a new technique to derive thermospheric temperature from space-based disk observations of far ultraviolet airglow. The technique, guided by findings from principal component analysis of synthetic daytime Lyman–Birge–Hopfield (LBH ...

Integration of Node Classification in Storm Surge Surrogate Modeling
Journal of Marine Science and Engineering, 2022 Surrogate models, also referenced as metamodels, have emerged as attractive data-driven, predictive models for storm surge estimation. They are calibrated based on an existing database of synthetic storm simulations and can provide fast-to-compute ...

Agronomy, 2021 Erosion is a major problem on agricultural lands in Europe. Erosion measurement tools have traditionally been focused on delocalized quantification but without mapping the real places inside the basin where the erosion took effect.
