Jamtalferner glacier in Silvretta has been the subject of mass balance monitoring since 1988. A stake network is maintained for the measurement of glacier mass balance. Complementary to mass balance data, glacier length changes and historical maps are available since about 1850. The basin precipitation is measured with rain gauges. A full energy balance station records air temperature and humidity, snow temperatures, snow height, short wave and long wave incoming and outgoing radiation, rain rate, wind speed and direction as well as snow cover by repeat obliqze photographs. The data is supplied to the world glacier monitoring service in Zurich and made available to the scientific community. The nearby Jamtal hut with internet, phone connection and seminar rooms provides excellent possibilities for researchers.
