Overview
The PME minPAR contains a tilt sensor to ensure proper orientation and a temperature sensor. Data is recorded on an internal SD card. The miniPAR is powered by 2 AA batteries and can be fitted with an anti-fouling miniWIPER to protect long-term data accuracy.
Measuring Photosynthetically Active Radiation
The miniPAR is fitted with an LI-192 Underwater Quantum Sensor manufactured by LI-COR. The sensor uses a silicon photodiode and glass optical filters to create a uniform sensitivity to light wavelengths in the 400-700nm range. It measures PAR from all angles in one hemisphere. PAR is a key indicator for understanding nutrient loading, photosynthesis, algae blooms, or other biological, chemical, or physical processes.
Battery Powered
PME is confident that the logger can continue collecting measurements for over one year before the batteries need to be replaced at a sampling interval of one minute. The miniPAR is constructed from strong Delrin plastic that does not easily crack or break.
Embedded Tilt Sensor
The miniPAR is unique among similar loggers in that it contains a tilt sensor to measure the orientation of the device. Since PAR measurement accuracy is dependent upon the sensor being pointed toward the water surface, the tilt sensor will alert the user if the sensor is rotated in a particular direction.
PME Software Included
PME software is provided with every miniPAR logger and can be found on the included SD card when it is connected to a computer. The software creates visual plots to read PAR measurements easily and allows the user to set the internal clock and sample rate.

Thin Ice: Year-Long Monitoring in Missouri Reservoirs
The value of multi-lake studies is well understood by international organizations like the Global Lake Ecological Observatory Network (GLEON) and the scientists who work tirelessly to provide data to the larger network. Rebecca North, an associate professor at the University of Missouri-Columbia , is one of many researchers involved in multi-lake research initiatives and conducting research locally in her home state. 
 
Having been born and raised on the shore of Lake Ontario, North grew up in a community that revolved around water. She also saw firsthand one of the worst water quality bodies of the world, the Bay of Quinte, decline throughout her lifetime.

Meadowbrook Creek in Syracuse, New York, has been monitored by Syracuse University (SU) faculty and students for over a decade. Originally established by Dr. Laura Lautz in 2012, the early years of the program focused on collecting grab water samples for laboratory analysis and evaluating the impact of urban land use, human activities, and natural processes on water resources. 
 
 Tao Wen , an Assistant Professor in SU’s Department of Earth and Environmental Sciences, took over the program in 2020 and upgraded the existing systems to include 4G modems that allowed for real-time data viewing.

Continuous data collection in Lancaster County, Pennsylvania, started about 5 years ago, and the county will be making a major upgrade over the next year—switching from relying solely on the internal storage of water quality sondes to telemetry units that enable real-time data viewing.

 Telling Lancaster County's Story Through Data 
Since the Lancaster County Conservation District started monitoring county waterways, the goal has remained the same, according to Amanda Goldsmith, Watershed Specialist for the Watershed Department.
