UK Polar Data Centre, Natural Environment Research Council, UK Research & Innovation. https://doi.org/10.5285/6be7d300-b42c-42f4-af59-2138e2a4dfe4 The datasets are temperature time series from strings of thermistors, each located at a discrete depth within one of six boreholes into Khumbu Glacier, Nepal. 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. The data are presented in whole or in part in Miles et al. (2018). Funding was provided by the NERC grant NE/P00265X/1 and NE/P002021/1. ***** PLEASE BE ADVISED TO USE VERSION 2.0 DATA ***** The VERSION 2.0 data set (see 'Related Data Set Metadata' link below) which contains an additional 11 months of measurements.

Details are provided in Miles et al. (2018). Resolution: The thermistors have an interchangeability of 0.4 degrees Celsius. After an ice bath calibration, previous studies have suggested that an accuracy of +/- 0.05 degrees can be achieved around 0 degrees. This is therefore the expected accuracy at 0 degrees, but represents an indication of uncertainty rather than a maximum limit (particularly as temperatures diverge away from 0 degrees). See Doyle et al. (2018) and Miles et al. (2018) for more information. Data quality: Detailed methodology, including accuracy estimation, is presented by Miles et al. (2018). Boreholes were drilled, and sensors installed, in April-May 2017 and 2018. Each thermistor typically logged temperature every 10 minutes for the time periods evident from each data record. For the three 2017 instrumented boreholes, this logging interval was changed to hourly measurements in May 2018. asNeeded completed
