Overview

Thank you for taking an interest in the FLASH (Flooding in Appalachian Streams and Headwaters) Initiative and CLIMBS (Climate Resilience through Multidisciplinary Big Data Learning, Prediction and Building Response Systems) project. The data provided in this repository is used across both projects.

This document provides guidance on the provided data and metadata. If you have questions about the data that this document cannot answer, please contact Lindsey Barnes, CLIMBS and FLASH research technician, at lindsey.barnes@louisville.edu.

Sensor Metadata

Contained in file 'SensorLocations_LASTUPDATE.csv'. Includes site descriptions, coordinates, sensor information, and upstream catchment area.

Data Guidance

The data provided is collected from the following sensors:

• Solinst water level and temperature pressure loggers

• Solinst water level, temperature, and conductivity pressure loggers

• Geolux non-contact depth and flow radars

• YSI EXO2 water quality sensors

• HOBO rain gauges and weather stations

Solinst Water Level Data

All Solinst water level data can be found by navigating to 'All-Data_NON-FLAGGED' > 'Water-Level-Pressure-Compensated' folder. Water level data is provided already barometric pressure compensated. These sensors require manual data collection and processing, so final data timestamps may vary between sites.

PLEASE NOTE that the provided data has not undergone a quality control error-flagging process at this time and should be treated with discretion.

Each Excel file in the 'Water-Level-Pressure-Compensated' folder contains three (3) sheets:

1. SITE_Compensated: All pressure-compensated water level data from installation date to most recent collection date.

   • Column descriptions:

   i. Date: Format MM/DD/YYYY HH:MM

   ii. Time: Timezone observed timestamp in five-minute intervals. Format HH:MM:SS AM/PM

   iii. LEVEL_cm: Pressure compensated water level in centimeters

   iv. CONDUCTIVITY_uScm: Specific conductivity in microsiemens per centimeter (when applicable)

2. Metadata: Information about the Compensated_Data sheet, including sensor model and serial number, recording interval, site name and coordinates, installation date, and barometric pressure compensation details. For quick reference of all Solinst sensors, site names, coordinates, and installation dates are also included in the 'SensorLocations' file.

3. Collection_Log: Log of sensor data collection and servicing, with field notes and manual water level depth readings for sensor accuracy checks.

All other data is telemetered (collected in real-time) and can be found in the 'All-Data_NON-FLAGGED' folder. PLEASE NOTE that the provided data has not undergone a quality control error-flagging process at this time and should be treated with discretion.

Files are labeled as 'SiteName_SensorType_InstallDate-LastDownloadDate'. An overview of each file is as follows:
