What are High-Frequency Data Sets?

Across science and engineering fields, remote devices (sensors) are increasingly being used to measure and record data for multiple parameters at high frequencies (readings every 15 minutes or even more frequently) and over long time spans (years). These sensors provide records of change that are essential research and monitoring tools. Sensor technologies are now used to collect high-frequency data on ecologically relevant variables ranging from soil moisture to stream conditions to correlating animal movements with environmental conditions.

Where Do Our Data Sets Come From?

Once we have focused our module topics, we will provide more information on the sources of our data sets. The table below lists possible module topics and data sources.
