Soil moisture and temperature data along the northeast facing hillslope at the Lower Montane site in the East River Watershed, Colorado

Soil moisture, temperature, and electrical conductivity were monitored with 5TE sensors (Decagon Inc.) located at 10 and 50 cm depth at four different locations along the northeast-facing slope at the Lower Montane site in the East River Watershed, Colorado, from Oct 2016 to Oct 2018. The purpose of this dataset was to inform hydrobiogeochemical analyses for the Watershed Function Scientific Focus Area (SFA), including helping to answer several research questions (see reference list for publications that used this dataset). The data are reported in four CSV files labeled by their location identifiers (ER-SMN1–5), and location metadata is provided in SM_loc.csv. In 2018–2019, wildlife interactions with the sensors led to several failures. In 2019, the sensors were replaced and/or repaired. The data from 2019 to 2024 at these and other sites in the area are part of another archive (Dafflon et al., 2025). These data products are part of the Watershed Function Scientific Focus Area collection effort to further scientific understanding of biogeochemical dynamics from genome to watershed scales.
