    • Intercomparison of spanish advanced lidars in the framework of EARLINET 

      Sicard, Michaël; Md. Reba, Mohd Nadzri; Rocadenbosch Burillo, Francisco; Gregorio López, Eduard; Kumar, Dhiraj; Tomás, S; Comerón Tejero, Adolfo; Molero, Francisco; Pujadas, M; Guerrero Rascado, Juan Luis; Alados, L; Pedrós, R; Martinez Lozano, José Antonio (2007)
      Text en actes de congrés
      Accés obert
      To extend and reinforce the action of the EARLINET- ASOS project, a nucleus of Spanish advanced lidars was created. Four systems were intercompared satisfactorily in terms of backscatter coefficients at two elastic wavelengths.

    • Morphological tools for range-interval segmentation of elastic lidar signals 

      Rocadenbosch Burillo, Francisco; Sicard, Michaël; Md. Reba, Mohd Nadzri; Tomás, S (2007)
      Text en actes de congrés
      Accés obert
      This article presents a preliminary semi-automated range-interval segmentation toolset for the identification of: 1) the apparent range of full overlap, 2) the clear-sky level (i.e., the molecular level), and cloud layers ...

    • Piece-wise variance method for signal-to-noise ratio estimation in elastic/Raman lidar signals 

      Md. Reba, Mohd Nadzri; Rocadenbosch Burillo, Francisco; Sicard, Michaël; Muñoz Porcar, Constantino; Tomás, S (2007)
      Text en actes de congrés
      Accés obert
      A straightforward signal-to-noise ratio (SNR) estimator for elastic/Raman lidar channels and related noise-induced errorbars is presented. The estimator is based on piece-wise estimation of the mean signal power and noise ...

    • Practical analytical backscatter error bars for elastic one-component lidar inversion algorithm 

      Rocadenbosch Burillo, Francisco; Md. Reba, Mohd Nadzri; Sicard, Michaël; Comerón Tejero, Adolfo (2010-06-10)

    • Results of site testing using an aerosol, backscatter lidar at the Roque de los Muchachos Observatory 

      Jiménez Fuensalida, Jesús; Muñoz Tuñón, Casiana; Sicard, Michaël; Md. Reba, Mohd Nadzri; Tomás Martínez, Sergio; Comerón Tejero, Adolfo; Batet Torrell, Óscar; Muñoz Porcar, Constantino; Rodríguez Gómez, Alejandro Antonio; Rocadenbosch Burillo, Francisco (2010-06-01)
      Article
      Accés obert
      The Roque de los Muchachos Observatory, located on the island of La Palma in the Canary Islands, is home of many astronomical facilities for its high sky quality. In the context of the Extremely Large Telescope Design ...

    • Seasonal variability of aerosol optical properties observed by means of a Raman lidar at an EARLINET site over Northeastern Spain 

      Sicard, Michaël; Rocadenbosch Burillo, Francisco; Md. Reba, Mohd Nadzri; Comerón Tejero, Adolfo; Tomás Martínez, Sergio; García Vizcaíno, David; Batet Torrell, Óscar; Barrios Porras, Ricardo Alfonso; Kumar, Dhiraj; Baldasano Recio, José María (2011-01-11)
      Article
      Accés obert
      The annual and seasonal variability of aerosol optical properties observed by means of a Raman lidar over Northeastern Spain has been assessed. The lidar representativeness has first been checked against sun-photometer ...

    • Statistical considerations on the extinction error variance for the Raman lidar inversion algorithm 

      Rocadenbosch Burillo, Francisco; Comerón Tejero, Adolfo; Sicard, Michaël; Md. Reba, Mohd Nadzri (2007)
      Text en actes de congrés
      Accés obert
      At the basis of the Raman lidar extinction inversion algorithm is the derivative of the logarithm of the ratio between the atmospheric nitrogen number density and the range-corrected Raman power return. While its computation ...
