Antarctic daily precipitation amounts for January 1979 - July 2017 from the RACMO version 3p2 limited area atmospheric model, along with flags that indicate extreme precipitation events
Two netcdf files are provided that contain daily precipitation amounts for January 1979 - July 2017 from the RACMO version 3p2 limited area, atmosphere-only model. The model is described in van Wessem, J. M., C. H. Reijmer, M. Morlighem, J. Mouginot, E. Rignot, B. Medley, and E. van Meijgaard, (2014) Improved representation of East Antarctic surface mass balance in a regional atmospheric climate model, Journal of Glaciology, 60, 761-770. The model was run over a 262 by 240 grid point domain covering Antarctica and parts of the Southern Ocean. The model was forced at the lateral boundaries by data from the European Centre for Medium-range Weather Forecasting (ECMWF) Interim reanalysis (ERA-Interim). Flags are provided for extreme precipitation events. A precipitation day was taken as a daily total of precipitation of greater than 0.02 mm. Extreme precipitation events were then taken as days when daily precipitation amount was greater than the 90th percentile of the daily precipitation values over the period 1979 - 2016.

Model-simulated and bias-corrected daily total precipitation from a reanalysis-driven Weather Research and Forecasting simulation of the Beas and Sutlej river basins in the Himalaya, 1980 to 2012
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.
