    • Estimation of integrated water vapor derived from Global Navigation Satellite System observations over Central-Western Argentina (2015–2018). Validation and usefulness for the understanding of regional precipitation events 

      Camisay, María Fernanda; Rivera, Juan Antonio; Mateo, María Laura; Mackern, María Virginia; Morichetti, Paola (ELSEVIER, 2019-10-07)
      ARTÍCULO PUBLICADO EN REVISTA EXTERNA. This study assesses the possibility of using Global Navigation Satellite System (GNSS) observations in combination with measurements of surface pressure and temperature to derive Integrated Water Vapor (IWVGNSS) estimates in Central-Western Argentina (CWA), a semi-arid region with complex topography. A significant agreement (coefficient of determination > 0.9) is observed between IWVGNSS and IWV estimates from radiosonde measurements, highlighting the capability of the GNSS stations to provide IWVGNSS estimates for a denser network. The variability of ...
    • Tropospheric Products from High-Level GNSS Processing in Latin America 

      Mackern, María Virginia; Mateo, María Laura; Camisay, María Fernanda; Morichetti, Paola Vanina (Editorial International Association of Geodesy Symposia, 2020-07-25)
      ARTÍCULO PUBLICADO EN REVISTA EXTERNA. The present geodetic reference frame in Latin America and the Caribbean is given by a network of about 400 continuously operating GNSS stations. These stations are routinely processed by ten Analysis Centres following the guidelines and standards set up by the International Earth Rotation and Reference Systems Service (IERS) and International GNSS Service (IGS). The Analysis Centres estimate daily and weekly station positions and station zenith tropospheric path delays (ZTD) with an hourly sampling rate. This contribution presents some attempts aiming ...
