Ice tilt time-series from sensors installed in boreholes drilled into Khumbu Glacier, Nepal, in 2017 and 2018 as part of EverDrill research project - VERSION 2.0
The datasets are ice tilt time series from strings of accelerometers, each located at a discrete depth within one of three boreholes into Khumbu Glacier, Nepal. Ice deformation can be derived from this tilt data, but has not yet been calculated. Boreholes were drilled in May 2017 and 2018 to investigate the internal properties of Khumbu Glacier, specifically ice thickness, temperature, deformation and structure, as part of the NERC-funded ''EverDrill'' research project. Supporting borehole information is provided as a related dataset.
Funding was provided by the NERC grant NE/P00265X/1 and NE/P002021/1.

Detailed methodology, including accuracy estimation, is presented in the referenced publication.
Resolution:
The accelerometers installed in 2017 have an accuracy of 800 mV g-1 stated by the manufacturer (where g is the normalised gravity vector). A further calibration was carried out (details in Doyle et al. (2018)), resulting in the absolute accuracy of the tilt sensors being determined to be less than ± 1 degree.
The digital sensors installed in 2018 also measured temperature, however, these were not calibrated and are therefore only accurate to ± 0.5 degrees Celsius.
