It has been recognized that human activities play a key role and must therefore be considered in future climate simulations. The representation of anthropization in land surface schemes within global earth system models is at a relatively nascent stage and must be improved for more accurate future projections of water resources. The understanding of the impact of anthropogenic processes has been hampered by the lack of consistent and extensive observations. Here, we present the Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment (LIAISE) project field campaign which brought together ground-based (surface energy budget estimated at 7 sites, 269 radio soundings made at 2 sites and multiple remote sensing instruments for profiling the lower atmosphere), airborne measurements (3 airplanes and numerous drones measuring surface and atmospheric properties) and satellite data (to derive estimates of irrigation timing, soil moisture, evapotranspiration and surface temperature) to improve our understanding of key natural and anthropogenic land processes and boundary layer feedbacks. The study area is in the Ebro basin of northeastern Spain in a hot, dry Mediterranean climate, with a sharp demarcation between a vast intensively irrigated region and a much drier rainfed zone to the east. Analysis of the observations reveal strong surface heterogeneities of evapotranspiration within the irrigated zone (differences upwards of approximately 7 mm day-1 between fields), linked to the crop type, vegetation phenology and soil moisture, all of which were modulated by irrigation. The significant surface flux differences between the irrigated and rainfed zones were found to result in strongly contrasting atmospheric boundary layer properties (between 2 supersites​ separated by 14 km) extending upwards through the lowest several km of the atmosphere.}}, author = {{Boone, Aaron and Bellvert, Joaquim and Best, Martin and Brooke, Jennifer K. and Canut-Rocafort, Guylaine and Cuxart, Joan and Hartogensis, Oscar and Moigne, Patrick Le and Miró, Josep Ramon and Polcher, Jan and Price, Jeremy and Seguí, Pere Quintana and Bech, Joan and Bezombes, Yannick and Branch, Oliver and Cristóbal, Jordi and Dassas, Karin and Fanise, Pascal and Gibert, Fabien and Goulas, Yves and Groh, Jannis and Hanus, Jan and Hmimina, Gabriel and Jarlan, Lionel and Kim, Ed and Dantec, Valérie Le and Page, Michel Le and Lohou, Fabienne and Lothon, Marie and Mangan, Mary Rose and Martí, Belén and Martínez-Villagrasa, Daniel and McGregor, James and Kerr-Munslow, Amanda and Ouaadi, Nadia and Philibert, Alban and Quiros-Vargas, Juan and Rascher, Uwe and Siegmann, Bastian and Udina, Mireia and Vial, Antoine and Wrenger, Burkhard and Wulfmeyer, Volker and Zribi, Mehrez}}, booktitle = {{Journal of the European Meteorological Society}}, issn = {{2950-6301}}, keywords = {{Anthropization, Irrigation, Agriculture, Field campaign, Surface energy budget, Evapotranspiration, Land–atmosphere interactions, Ebro basin}}, number = {{Dez.}}, publisher = {{Elsevier BV}}, title = {{{The Land Surface Interactions with the Atmosphere over the Iberian Semi-Arid Environment (LIAISE) field campaign}}}, doi = {{10.1016/j.jemets.2025.100007}}, volume = {{2}}, year = {{2025}}, } @misc{11432, abstract = {{Currently, numerous single track railway lines are disused due to economic reasons. One way they could be reactivated for bidirectional on demand traffic is by small cabin-like vehicles, lateral stabilized by a system of control moment gyroscopes and a moveable mass. Regarding such a vehicle, there is currently no reference in comparison with other vehicles and no experimental experience or the like. To ensure the functionality and safety of the vehicle even before its realization, a model-based design is carried out for development, analysis, optimization and testing. This paper is focused on the co-simulation of such a vehicle that is controlled by a longitudinal control. In order to take into account the complex interaction between the longitudinal dynamics and the running gear, the entire system must be considered here including the wheel/rail interaction. Co-simulations are performed considering both the mechanical model of the vehicle and the control of the longitudinal dynamics of the overall system. The simulation results show that functionality and safe operation can be ensured by the vehicle longitudinal controls. As a result, the simulation and the measurement of the real system show a good match. By means of HIL and co-simulations, function tests could be shifted to earlier development stages, in order to accelerate the overall development.}}, author = {{Hanselle, Raphael and Stork, Dominic and Lück, Sönke and Rasche, Rainer and Naumann, Rolf and Witte, Stefan}}, booktitle = {{ Advances in Dynamics of Vehicles on Roads and Tracks III Proceedings of the 28th Symposium of the International Association of Vehicle System Dynamics, IAVSD 2023, August 21–25, 2023, Ottawa, Canada - Volume 1: Rail Vehicles}}, editor = {{Huang, Wei and Ahmadian, Mehdi }}, isbn = {{978-3-031-66970-5}}, issn = {{2195-4364}}, keywords = {{field and laboratory testing, autonomous railway vehicles, vehicle control and mechatronics, co-simulation}}, location = {{Ottawa, Canada}}, pages = {{514--523}}, publisher = {{Springer Nature}}, title = {{{Simulation of a Longitudinal Control System for an Automated Driving Self-Stabilized Monorail Vehicle}}}, doi = {{https://doi.org/10.1007/978-3-031-66971-2_54}}, year = {{2024}}, } @misc{9422, abstract = {{Global trends towards the rapidly increasing use of information systems (IS) apply to the IS research domain and related publications.
