Urban Air Mobility demand forecasting: modeling evidence from the case study of Milan (Italy) by Pierluigi Coppola, Francesco De Fabiis, Fulvio Silvestri

“…Demand forecasting is based on random utility mode choice models, which include factors related to the individuals’ perception of vertical take-off/landing and low altitude flying over urbanized areas. The use cases of UAM services include airport shuttles, intercity air connections, and “air-taxis”, i.e., UAM services for short-trips within the metropolitan area. …”

SPATIAL ANALYSIS OF ENVIRONMENTAL AND ANTHROPOGENIC INFLUENCES ON NITRATE CONCENTRATION IN SHALLOW GROUNDWATERS. CASE STUDY: RUSCOVA VALLEY, MARAMUREŞ MOUNTAINS (ROMANIA) by GHEORGHE KUCSICSA, VASILE POPOVICI

“…In addition to nitrate concentration, determined in 26 water samples, several parameters were measured during the field surveys: water pH, temperature, depth to water and altitude of the sample point. Moreover, several environmental and anthropogenic potential explanatory factors for nitrate concentration were analysed: depth to water, land use/land cover, lithology, soil texture, number of households and population density. …”

The Relationship between the Atmospheric Heat Source over Tibetan Plateau and the Westerly-Monsoon Evolution in August and Its Physical Mechanism by Chunxue Wang, Yueqing Li

“…The synthetic analysis indicated that when the AHS was strong, a positive anomaly of a horizontal temperature gradient appeared over TP, which was conducive to the southward shift of the high-altitude temperature gradient center, resulting in the southward position of the axis of the 200 hPa westerly jet, and an upward and downward inclined westerly anomaly zone appeared from the south slope of TP to the main body and its north slope. …”

TIE‐GCM ROPE ‐ Dimensionality Reduction: Part I by Piyush M. Mehta, Richard J. Licata

“…This work focuses on the dimensionality reduction step of the ROPE development process and addresses three limitations of the proof‐of‐concept: (a) extending the altitude upper boundary from 450 km to nearly 1000 km, (b) employing deep learning for nonlinear dimensionality reduction over principal component analysis (PCA) for improved performance during storm periods, and (c) maintaining the spatial resolution of the physical TIE‐GCM model, without down‐sampling, to preserve the spatial scales and variations. …”
