    • An extraordinary dry season precipitation event in the subtropical Andes: drivers, impacts and predictability 
      Valenzuela, Raúl; Garreaud Salazar, René Darío; Vergara, Iván; Campos, Diego; Viale, Maximiliano; Rondanelli Rojas, Roberto Francisco (Elsevier, 2022)
      A major storm impacted the subtropical Andes during 28-31 January 2021 producing 4-days accumulated precipitation up to 100 mm over central-south Chile. These are high accumulations even for winter events but the storm ...
    • Automated low-cost LED-Based sun photometer for city scale distributed measurements 
      Garrido, Cristóbal; Toledo, Felipe; Díaz Quezada, Marcos Andrés; Rondanelli Rojas, Roberto Francisco (MDPI, 2021)
      We propose a monochromatic low-cost automatic sun photometer (LoCo-ASP) to perform distributed aerosol optical depth (AOD) measurements at the city scale. This kind of network could fill the gap between current automatic ...
    • Contaminant emissions as indicators of chemical elements in the snow along a latitudinal gradient in southern Andes 
      Pizarro, Jaime; Vergara, Pablo M.; Cerda, Sergio; Cordero, Raúl R.; Castillo Castillo, Ximena Andre; Rowe, Penny M.; Casassa Rogazinski, Gino; Carrasco, Jorge; Damiani, Alessandro; Llanillo, Pedro J.; Lambert, Fabrice; Rondanelli Rojas, Roberto Francisco; Huneeus Lagos, Nicolás Jorge; Fernandoy, Francisco; Alfonso, Juan; Neshyba, Steven (Nature, 2021)
      The chemical composition of snow provides insights on atmospheric transport of anthropogenic contaminants at different spatial scales. In this study, we assess how human activities influence the concentration of elements ...
