Abstract

Photosynthetically Active Radiation (PAR) data have been collected at multiple sites in Dead Run watershed (near Woodlawn, MD) over variable periods of time since June 2012. The deployed device is a Photosynthetic Light (PAR) Smart Sensor S-LIA-M003 by Onset. The sensor measures light intensity for frequencies relevant to photosynthesis in units of µmol/m2/sec. Sensor specifications are posted at http://www.onsetcomp.com/products/sensors/s-lia-m003. Sensors are configured to collect data at a 5-minute interval. Data are stored in an Onset Microstation Data Logger H21-002 or H21-USB and downloaded manually every 60 days.
