Youngmeyer Ranch (KS) Stream Temperature, Intermittency, and Conductivity Data

This resource contains data from stream temperature, intermittency, and conductivity (STIC) loggers placed at the Youngmeyer Ranch field station (KS, USA) for July 16, 2021 to December 31, 2022 at 15 minute resolution as part of the NSF-funded Aquatic Intermittency effects on Microbiomes in Streams (AIMS) project (award IOA #2019603).

The file YMR_SiteInfo.csv contains site locations for each sensor and has three fields:
- siteID = name of site
- lat = latitude of site
- long = longitude of site

The files YMR_AllSTICsCleaned_20210716-20211231.csv and YMR_AllSTICsCleaned_20220101-20221231.csv contain the 2021 and 2022 data, respectively, and have the following fields:
- datetime = date and time of reading (time zone = UTC).
- siteID = name of site for linking to file KNZ_SiteInfo.csv
- SN = serial number of STIC logger used for that reading.
- condUncal = uncalibrated (raw) conductivity output from the STIC
- tempC = temperature [degrees Celsius]
- SpC = specific conductviity in us/cm
- wetdry = binary classification of \"wet\" (water present) or \"dry\" (no water present) for that timestep
- qual_rating = qualitative data rating crit (described below)
- QAQC = flags from data QAQC process (described below)

Due to data logger errors, maintenance, etc. there are not data for all sites at all timesteps.

qual_rating description:
- \"excellent\" = STIC was (1) calibrated prior to deployment, and (2) stayed operational throughout 95% of the download period, and (3) was not displaced from streambed (i.e., the external electrodes were within 1 cm from stream bed at the time of download indicating minimal erosion/deposition), and (4) data from sensor roughly agree with field observations of wet/dry (i.e., >1000 Lux sensor reading on day of removal corresponds to field observations of water at STIC).
- \"good\" = (1) STIC stayed operational throughout the entire download period, and (2) the external electrodes were within 1 cm from stream bed at the time of download, and (3) data from sensor roughly agree with field observations of wet/dry, but (4) the STIC was not calibrated prior to deployment.
- \"fair\" = (1) STIC stayed operational throughout 75% or more of the download period, and (2) data roughly agree with field observations, and/or (3) the external electrodes were between 1-3 cm from streambed at the time of download.
- \"poor\" = (1) STIC stayed operational throughout less than 75% of the download period, and/or (2) the external electrodes were >3 cm from streambed at the time of download, and/or (3) data does NOT agree with field observations.

QAQC description:
- \"N\" = application of calibration curve resulted in negative value for SpC; this was changed to a value of 0.
- \"A\" = wetdry reading flagged as a potential anomaly (i.e., short period of dry surroudned by long period of wet or vice versa)
An empty field here indicates no flags were generated. If multiple flags were generated, they were concatenated.
