Soil temperature series in Vallon de Nant catchment, Switzerland
Soil temperature has been recorded continuously at 4 sites in the Vallon de Nant, Switzerland, from July 21st, 2009 to November 16th, 2018. The elevation of the sites ranges between 1240 and 2640 m asl. All plots are on calcareous bedrock. Dominant species are: T1: montane forest dominated by Fagus...

| Summary: | Soil temperature has been recorded continuously at 4 sites in the Vallon de Nant, Switzerland, from July 21st, 2009 to November 16th, 2018. The elevation of the sites ranges between 1240 and 2640 m asl. All plots are on calcareous bedrock. Dominant species are: T1: montane forest dominated by Fagus sylvatica and Abies alba in overstorey, Sanicula europaea and Oxalis acetosella in understorey. T2: mesohygrophilous, subalpine pasture dominated by Carex ferruginea and Alchemilla vulgaris. T3: lower alpine, mesophilous grassland, dominated by Festuca melanopsis, Sesleria caerulea and Carex ferruginea. T4: upper alpine grassland, dominaed by Salix herbacea, Salix retusa and Polygonum viviparum. Measures are realized every hour using a temperature logger GeoPrecision M-Log5W (GeoPrecision GmbH, Ettlingen, Germany) with an accuracy of +/- 0.1°C @0°C.
