    • Assessing Obukhov length and friction velocity from floating lidar observations: A data screening and sensitivity computation approach 

      Silva, Marcos Paulo Araujo da; Rocadenbosch Burillo, Francisco; Farré Guarné, Joan; Salcedo Bosch, Andreu; González Marco, Daniel; Peña Diaz, Alfredo (Multidisciplinary Digital Publishing Institute (MDPI), 2022-03-14)
      Article
      Open Access
      This work presents a parametric-solver algorithm for estimating atmospheric stability and friction velocity from floating Doppler wind lidar (FDWL) observations close to the mast of IJmuiden in the North Sea. The focus of ...
    • Atmospheric boundary layer height disambiguation using synergistic remote sensing observations: case examples from VORTEX-SE 

      Rocadenbosch Burillo, Francisco; Tanamachi, Robin; Silva, Marcos Paulo Araujo da; Villalonga, Joan; Frasier, Stephen J.; Turner, David Dave (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2020)
      Conference report
      Open Access
      Synergistic remote sensing of the atmosphere, combined with adaptive techniques, offers unprecedented opportunities to characterise the evolution of key atmospheric features such as the Atmospheric Boundary Layer (ABL). ...
    • Clouds’ microphysical properties and their relationship with lightning activity in northeast Brazil 

      Pereira de Abreu, Lizandro; Andrade Goncalves, Weber; Vieira Mattos, Enrique; Rodrigues Mutti, Pedro; Torres Rodrigues, Daniele; Silva, Marcos Paulo Araujo da (Multidisciplinary Digital Publishing Institute (MDPI), 2021-11-01)
      Article
      Open Access
      The Northeast region of Brazil (NEB) has a high rate of deaths from lightning strikes (18% of the country’s total). The region has states, such as Piauí, with high mortality rates (1.8 deaths per million), much higher than ...
    • Convective boundary-layer height estimation from combined radar and Doppler lidar observations in VORTEX-SE 

      Villalonga, Joan; Beveridge, Susan L.; Silva, Marcos Paulo Araujo da; Tanamachi, Robin; Rocadenbosch Burillo, Francisco; Turner, David Dave; Frasier, Stephen J. (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2020)
      Conference report
      Open Access
      The Verification of the Origins of Rotation in Tornadoes Experiment Southeast (VORTEX-SE) provides a wealth of long-duration, high-resolution, vertically pointing observations from active and passive ground-based remote ...
    • Motivating a synergistic mixing-layer height retrieval method using backscatter lidar returns and microwave-radiometer temperature observations 

      Silva, Marcos Paulo Araujo da; Rocadenbosch Burillo, Francisco; Tanamachi, Robin; Saeed, Umar (Institute of Electrical and Electronics Engineers (IEEE), 2022-03-10)
      Article
      Open Access
      Mixing-Layer-Height (MLH) retrieval methods using backscattered lidar signals from a ceilometer (Jenoptik CHM-15k Nimbus) and temperature profiles from a Microwave Radiometer (MWR, HATPRO RPG) are compared in terms of their ...
    • Offshore Doppler Wind LiDAR assessment of atmospheric stability 

      Silva, Marcos Paulo Araujo da; Salcedo Bosch, Andreu; Gutiérrez Antuñano, Miguel Ángel; Rocadenbosch Burillo, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      This paper tackles atmospheric stability typing using a Zephyr™ 300 offshore Doppler Wind Lidar in the context of its progressive acceptance in the offshore wind-energy industry. The lidar-retrieved wind-shear exponent, ...
    • Variance processing for stable boundary-layer height estimation using backscatter lidar data: A discussion 

      Muñoz Porcar, Constantino; Silva, Marcos Paulo Araujo da; Saeed, Umar; Rey Micolau, Francesc; Pay Pérez, M. Teresa; Rocadenbosch Burillo, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      In this paper we present a method for estimating the height of the nocturnal stable boundary layer by using lidar measurements and a single radiosonde for unambiguous initial guess. The method relies on the correlation ...
