  • This dataset contains atmospheric data from the WRF (Weather Research and Forecasting) model. The model is located over the Dudh Koshi Valley, and the model was run for July 2013. WRF version 3.8 was used. This data has been used to create and examine the effectiveness of a new debris-covered glacier representation in the WRF model. There are eight NetCDF files containing the data: The model with the default glacier landmask in the model (WRF_DudhKoshiHimalayas_201306_CleanIceGlaciers.nc); the model with a new representation of debris-covered glaciers (WRF_DudhKoshiHimalayas_201306_DebrisCoverGlaciers.nc); and six sensitivity tests varying albedo, emissivity and roughness length (WRF_DudhKoshiHimalayas_201306_DebrisCoverGlaciers_albedoHIGH.nc, etc).

  • This dataset collection contains momentum budget and snow removal experiment model data from Dudh Koshi Valley in the Nepalese Himalaya. The Weather Research and Forecasting (WRF) model was run for two months, July 2013 and December 2014, to investigate the momentum budget components of the winds in the Dudh Koshi Valley. The two runs were repeated with the permanent snow and ice changed to rock. This data was collected as part of the Dynamical drivers of the local wind regime in a Himalayan valley project (NE/L002507/1).

  • This dataset contains momentum budget model data from Dudh Koshi Valley in the Himalayas. The Weather Research and Forecasting (WRF) model was run for two months, July 2013 and January 2014, to investigate the momentum budget components of the winds in the Dudh Koshi Valley. This data was collected as part of the Dynamical drivers of the local wind regime in a Himalayan valley project (NE/L002507/1). The WRF model has been modified to output the momentum budget components. There are four nested domains, of 27 km, 9 km, 3 km and 1 km resolution. The inner 1 km is 130 km by 130 km, centred on 27.98N, 86.76E.

  • High-resolution simulations of daily precipitation over the Beas and Sutlej basins in the Himalaya from 1980 to 2012 were conducted using the Weather Research and Forecasting (WRF) model by the British Antarctic Survey, Cambridge, UK. It was shown that applying a non-linear bias-correction method to the model precipitation output resulted in much better results. The work formed part of the project ''Sustaining Himalayan Water Resources in a Changing Climate (SusHi-Wat)'' during 2015 to 2018, and was funded by the UK Natural Environmental Research Council grant number NE/N015592/1. The datasets produced are necessary as accurate fine-scale estimates of precipitation over catchments in the Himalaya mountain range are required for providing input to hydrological models, as well as identifying precipitation extremes for assessing hydro-meteorological hazards.

  • Simulated ice thickness (ice, metres, 100 m grid spacing) and supraglacial debris thickness (debris, metres, 100 m grid spacing) for Khumbu Glacier, Nepal, produced using the iSOSIA ice-flow model presented in Rowan et al. (2021; Journal of Geophysical Research-Earth Surface). The model domains used for the entire glacier and active glacier simulations (metres above sea level, 100 m grid spacing), and the present-day ice thickness estimate (metres, 30 m grid spacing) used to create the subglacial topography are included. The files contained in this collection present the outputs from three experiments carried out in Rowan et al. (2021; Journal of Geophysical Research-Earth Surface): 1. Simulation with a continuous debris layer, where h0 = 0.23 m and dT = 1.5 degC, showing the effect of change in mean annual air temperature to the present day (2015 CE) from 1.5 degC relative to the Little Ice Age 2. Simulation with a discontinuous debris layer, where h0 = 0.94 m and dT = 1.5 degC 3. Simulation with a discontinuous debris layer of the active glacier, where h0 = 0.94 m and dT = 1.5 degC The subglacial DEMs used for the model domains for the entire glacier and the active glacier, and the present-day (2015 CE) ice thickness estimated by Rowan et al. (2015, EPSL) to create the subglacial topography are also included (3 files). Funded by NERC under grant: NE/P00265X/1 "EverDrill: Accessing the interior and bed of a Himalayan debris-covered glacier to forecast future mass loss" to Duncan Quincey (PI) and Ann Rowan (CoI).

  • Simulated ice thickness (ice, metres), supraglacial debris thickness (dh, metres) and velocity (velocity, metres per year) for Khumbu Glacier, Nepal, produced using the iSOSIA ice-flow model presented in Rowan et al. (in revision, Journal of Geophysical Research-Earth Surface). The files contained in this collection present the outputs from three experiments: Experiment 1, six files, three simulations showing the effect of change in mean annual air temperature to the present day from 1.5 degC to 3.5 degC relative to the Little Ice Age. Experiment 2, four files, two simulations showing the effect of change in the h0 constant describing the reduction in sub-debris melt with debris thickness. Experiment 3, four files, two simulations, showing the effect of change in mean annual air temperature to the present day from 2.5 degC to 3.5 degC relative to the Little Ice Age where h0 = 1.1 m. Results from the optimal simulation, nine files, one simulation, showing results for simulated ice thickness, supraglacial debris thickness and glacier velocity for the Little Ice Age, 1984 CE and 2015 CE. Funding was provided by the NERC grant NE/P00265X/1. ***** PLEASE BE ADVISED TO USE VERSION 2.0 DATA ***** The VERSION 2.0 data set (see ''Related Data Set Metadata'' link below) differs from that presented here in Version 1.0 in that the h0 values were revised based on a maximum debris thickness of 2.0 m (compared to 4.0 m in Version 1.0) and the simulations of the active glacier extent were not part of Version 1.0.
