🚀 Excited to announce the release of our MATLAB-based Downburst Simulator code! ⛈️⚡ Our 2D downburst analytical model, now available on Zenodo, simulates horizontal mean wind velocities caused by traveling downbursts immersed in an atmospheric boundary layer. Using a parametric-analytical approach and the Teaching-Learning-Based Optimization (TLBO) algorithm, this tool optimizes downburst parameters based on real data from anemometric or lidar measurements. The optimization process adjusts the geometric and kinematic parameters to fit real measurement data, minimizing errors between recorded and simulated data. Additionally, the TLBO algorithm can analyze the variability of downburst parameters for full-scale anemometric records. The code includes visualization features for comprehensive analysis. 🔗 Explore the downburst simulator here: https://lnkd.in/d9h8yz5u This work builds on the following research articles: 1. Andi Xhelaj, Massimiliano Burlando, Giovanni Solari (2020) - A general-purpose analytical model for reconstructing the thunderstorm outflows of traveling downbursts immersed in ABL flows, Journal of Wind Engineering and Industrial Aerodynamics, 207, 104373. https://lnkd.in/dBQWcVgk 2. Andi Xhelaj, Massimiliano Burlando (2022) - Application of metaheuristic optimization algorithms to evaluate the geometric and kinematic parameters of downbursts, Advances in Engineering Software, 173, 103203. https://lnkd.in/dUm8Nepg 3. Andi Xhelaj, Massimiliano Burlando (2024) - Application of the teaching–learning-based optimization algorithm to an analytical model of thunderstorm outflows to analyze the variability of the downburst kinematic and geometric parameters, Natural Hazards and Earth System Sciences, 24(5), 1657-1679. https://lnkd.in/d8TWvDjk The code allows the analysis and simulation of downburst events and is intended for researchers and engineers working in the field of wind engineering and atmospheric sciences. #Downburst #Simulator #Research #OpenSource #WindEngineering #Zenodo

Is it possible to quickly simulate #ray #tracing #radio #occultation ray path in a three-dimensional environment? Can this be done with high quality and only geometric optics? Our latest publication in the Journal of Geodesy proves that it is possible! Using a new innovative approach to calculate refractive gradients, we have developed a 3D ray tracing algorithm that forms the basis for effective reconstruction of GNSS signals in three-dimensional models, e.g. in GNSS tomography. We test our algorithm in different scenarios with different initial conditions, atmospheric conditions and a priori models. We prove a comparable quality between our algorithm and the most popular 2D Radio Occultation Processing Package (ROPP). For more information and detailed results, see the article: Cegla, A., Rohm, W., Moeller, G. et al. GNSS signal ray-tracing algorithm for the simulation of satellite-to-satellite excess phase in the neutral atmosphere. J Geod 98, 42 (2024). https://lnkd.in/duu33Z3Q

New radar to be used to take first 3D measurements of Northern Lights

I am thrilled to have successfully completed the course "Remote Sensing and Satellite Image Processing with the EOS Platform" from GIU - Geo University. This journey has expanded my knowledge and skills in remote sensing, satellite image analysis, and leveraging the EOS platform for innovative solutions. Looking forward to applying these skills to tackle real-world challenges and contribute to impactful projects! #RemoteSensing #SatelliteImaging #ProfessionalDevelopment #EOSPlatform #LearningJourney

Interested in novel #geospatial #analysis applications and how they can help inform social science and public policy-related questions❓ Our upcoming #Geo4Dev #workshop (#free) https://lnkd.in/eYmrQeNW in #WashingtonDC, led by Xiaoxuan Li (Shawn) from New Light Technologies NLT, will guide users through the steps to combine publicly accessible Airborne Light Detection and Ranging (LiDAR) and Synthetic Aperture Radar (SAR) data to estimate woody cover in Brazil. The workshop will cover #data types and preprocessing, model estimation and selection, #visualization of predictions, and uncertainty calculations. Xiaoxuan and his coauthors developed this approach as part of their 2023 paper in Remote Sensing of Environment, “Quantifying the sensitivity of L-Band SAR to a decade of vegetation structure changes in savannas”. This workshop is a postlude to the Center for Effective Global Action (CEGA)’s annual Measuring Development (MeasureDev) conference. This is an in-person workshop only. Please bring your own laptop. No prior work is expected, but foundational knowledge of R will be required. Please contact Fiona Kastel (fkastel@3ieimpact.org) if you would like to participate but are unsure if you meet this prerequisite. Register here ⬇ https://lnkd.in/eYmrQeNW
