Subglacial water discharge exerts an important control on the speed of glacier flow, among other important processes. The amount of subglacial water discharge and the structure of the subglacial drainage system through which is passes vary on hourly to seasonal timescales. However, understanding these important characteristics of subglacial water drainage is hindered by the inaccessibility of the glacier bed. In 2016, seismic and weather data were collected from around Taku Glacier, Alaska, to reveal the structure and evolution of the subglacial drainage system. This study is reported in: Vore, M. E., T. C. Bartholomaus, J. P. Winberry, J. I. Walter, and J. M. Amundson, (under review in November 2018, following minor revisions), Seismic tremor reveals spatial organization and temporal changes of subglacial water system, Journal of Geophysical Research – Earth Surface. This dataset consists of weather data collected during the 2016 melt season at Taku Glacier and used in the above referenced publication for the purpose of modeling meltwater inputs to Taku Glacier. The accompanying seismic data is archived with the IRIS DMC (http://ds.iris.edu/mda/ZQ?timewindow=2015-2016) Data reported here were collected by two Vaisala WXT520 and one Onset HOBO tipping bucket rain gauge deployed off ice, approximately 100 m from the margin of Taku Glacier at two locations, station ETIP (Eastern tip of Taku Glacier) and station TWLV (Adjacent to the location where the glacier is twelve-hundred meters thick). These weather instruments were co-located with seismometers. One WXT520 and the rain gauge at ETIP, at sea level at the glacier terminus, and the second WXT520 at TWLV, at 600 m and approximately 13 km upglacier of the terminus.
