Mediterranean high mountain meteorology from continuous data obtained by a permanent meteorological station at Sierra Nevada, Spain. European Geosciences Union General Assembly 2011. Vienna, Austria, 3-8 April 2011. pdf [2.71 MB]The Guadalfeo Project was a scientific study whose main objective was to advance in the scientific knowledge
of the hydrological processes taking place in the Guadalfeo River Basin at Sierra Nevada Mountains. As part
of the Project, the meteorological station of Refugio Poqueira was installed in November 2004 at 2500 m.a.s.l.
Since then and up to now, 5-minutes data have been consistently recorded concerning precipitation, temperature,
relative humidity, solar radiation, wind speed and direction, and downward longwave radiation. The precipitation
reaches in this site a measured mean value of 750 mm/year, 60% of it as snow. The variability between years is
outstanding, ranging from 467 mm/year to 1250 mm/year and from 40% to 70% of snow. The mean temperature
is 6.4 ºC, falling to 1.4ºC during the winter months. The mean relative humidity of 50% is maintained during the
winter as well. The collected data highlight some unique characteristics of high mountain regions in Mediterranean
environments, where the snow is subjected to very a special combination of temperature, humidity and radiation.
Thanks to this knowledge, we were able to develop, among other applications, a physically based snowmelt model
that detected high rates of evaporation from the snow. |
