This dataset provides daily estimates of the Snow Water Equivalent (SWE) using data from 46 COSMOS-UK sites across the United Kingdom. One set of estimates is derived from the cosmic ray neutron sensor and provides an estimate of the average SWE within the sensor’s large (>100m) footprint. Other SWE estimates are based on either a snowmelt model, or, for certain sites, either a snow depth sensor or a buried 'SnowFox' neutron sensor. Additionally, daily neutron counts, the albedo, and a collection of figures for each snow event are provided.

Provenance & quality

The dataset lists data from all snow days, detected through their effect on the measured albedo, from the date of installation of each COSMOS-UK site up to summer 2019. Comparison of the available SWE estimates suggest typical uncertainties (1 standard deviation) of less than about 4mm for both the CRNS and SnowFox estimates, 4mm for the depth-based estimate and 5mm for the snowmelt model.
