STATNet: Spatial-temporal attention in the traffic prediction

Alexandre Massoud Alahi, Seyed Mohamad Moghadas, Amin Gheibi

Recent traffic flow prediction methods are lacking abilities to determine predictive features. Thus, they will propagate the error in the next timestamps. In this paper, first, we assess the role of spatial and temporal features on the traffic speed predic ...

Climatology of atmospheric boundary layer height over Switzerland

Benjamin Jérémy Laurent Heutte

Determining the height of the planetary boundary layer (PBL) is of crucial importance as it is a key parameter in air-quality modelling and weather forecasting. Continuous remote sensing measurements allow to estimate this parameter based on temperature, h ...

Numerical Weather Prediction and Artificial Neural Network Coupling for Wind Energy Forecast

Fernando Porté Agel, Jiannong Fang, Lorenzo Donadio

In the past two decades, wind energy has been under fast development worldwide. The dramatic increase of wind power penetration in electricity production has posed a big challenge to grid integration due to the high uncertainty of wind power. Accurate real ...

Augmenting the performance of impoverished sensor networks using machine learning and time reversal: Application to lightning nowcasting and location

Amirhossein Mostajabi

Lightning is formed in the atmosphere through the combination of intricate dynamic and microphysical processes. Mainly due to this complexity, attempts to solve the important problem of lightning prediction have generally failed to yield accurate results. ...

Secondary ice production in summer clouds over the Antarctic coast: an underappreciated process in atmospheric models

Athanasios Nenes, Alexis Berne, Georgia Sotiropoulou, Etienne Gabriel Henri Vignon

The correct representation of Antarctic clouds in atmospheric models is crucial for accurate projections of the future Antarctic climate. This is particularly true for summer clouds which play a critical role in the surface melting of the ice shelves in th ...

The relative contribution of secondary ice processes in Alpine mixed-phase clouds

Athanasios Nenes, Alexis Berne, Georgia Sotiropoulou, Paraskevi Georgakaki, Etienne Gabriel Henri Vignon

In-situ observations of mixed-phase clouds (MPCs) forming over mountain tops regularly reveal that ice crystal number concentrations (ICNCs) are orders of magnitude higher than ice-nucleating particle concentrations. This discrepancy has often been attribu ...

Simulating Mold Risks under Future Climate Conditions

Tobias Kippenberg, Rui Ning Wang, Anat Siddharth, Viacheslav Snigirev, Junqiu Liu, Wenle Weng, Jijun He

This research tests the potential susceptibility of a prevalent, residential, wall assembly to the risk of sustained mold-growth in predicted future climate conditions. Here, the authors demonstrate a methodology that combines hygrothermal and mold-growth ...

Building Electricity Demand Forecasting with Temporal Hierarchies

Lorenzo Donadio

Accurate building electricity load forecasts play a major role in the energy transition, as they facilitate flexibility deployment, grid stability and overall reduce costs and CO2 emissions. This research leaverages forecasting and reconciliation of tempor ...

The Role of Occupants in Buildings’ Energy Performance Gap: Myth or Reality?

Dolaana Khovalyg, Matteo Favero, Verena Marie Barthelmes

Buildings’ expected (projected, simulated) energy use frequently does not match actual observations. This is commonly referred to as the energy performance gap. As such, many factors can contribute to the disagreement between expectations and observations ...

Informed scenario-based RRT∗ for aircraft trajectory planning under ensemble forecasting of thunderstorms

Maryam Kamgarpour, Eduardo Andres Enderiz

Thunderstorms represent a major hazard for flights, as they compromise the safety of both the airframe and the passengers. To address trajectory planning under thunderstorms, three variants of the scenario-based rapidly exploring random trees (SB-RRTs) are ...
