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.

This dataset consists of field measurements of Pseudogymnoascus roseus DNA concentrations in soil and three edaphic factors (soil temperature, water potential and snow depth) at Mars Oasis, Alexander Island, from 2009 to 2012, under different temperature, irrigation and substrate (glucose, glycine and tryptone soy broth) treatments. Laboratory measurements of hyphal extension rates, conidial germination, numbers of conidia produced per colony of fungus and specific enzyme activities of three P. roseus isolates are also included.
