Small Footprint Solar/Wind-powered CASTNET System Dataset

Published by U.S. EPA Office of Research and Development (ORD) | U.S. Environmental Protection Agency | Metadata Last Checked: August 02, 2025 | Last Modified: 2017-08-02
In this Research Effort “Small Footprint Solar/Wind-Powered CASTNET System” there are two data sets. One data set contains atmospheric concentration measurements, at the standard CASTNET site at Cowetta, NC (COW005) and the special CASTNET site at Screwdriver Knob, Cowetta, NC (COW137); the other data set contains test data used to evaluate the small footprint monitoring systems operating conditions/limits. The measurement parameters for the atmospheric concentrations are: Site ID, Year, Dates , SO2 ug/m3, SO4= ug/m3, HNO3 ug/m3, NO3- ug/m3, NH4+ ug/m3, Total NO3- ug/m3, Ca++ ug/m3, K+ ug/m3, Mg++ ug/m3, Na+ ug/m3, Cl- ug/m3. The test data set contains the Site ID, the Date and Time, Battery Voltage (Volts), Flow Rate (lpn), Temp (C), Solar Output (watts), and Wind Output (watts). This dataset is associated with the following publication: Baumgardner, R., C. Rogers, M. Puchalski, J. Walker, T. Lavery, and K. Mishole. Small Footprint Solar/Wind Powered CASTNET System. U.S. Environmental Protection Agency, Washington, DC, USA, 2017.
