Glacier mass balance Jamtalferner, Silvretta, Austria, 1990/1991@en

The glacier mass balance of Jamtalferner has been measured annually since 1988/1989 with the direct/glaciological method. Winter mass balance has been determined for 1 May in all years. The mass balance records are complemented by precipitation measurements at a gauge close to the glacier tongue and climate data recorded at the village of Galtür.

自1988/1989年度起，科研人员采用直接冰川学方法（direct/glaciological method）对扬塔费尔纳冰川（Jamtalferner）的冰川物质平衡开展年度观测。所有年份的冬季物质平衡均以5月1日作为测定截止日。该物质平衡观测记录还辅以两项配套数据：一是在靠近该冰川冰舌的雨量计处获取的降水观测数据，二是在加尔图尔（Galtür）村落记录的气候观测数据。
