Abstract


Photosynthetically Active Radiation (PAR) data have been collected at six sites in Dead Run (near Woodlawn, MD) since June 2012 by the Center for Urban Environmental Research and Education at University of Maryland, Baltimore County (http://cuere.umbc.edu) as part of NSF project CBET-0854307. 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 a Onset Microstation Data Logger H21-002 http://www.onsetcomp.com/products/data-loggers/h21-002 and downloaded manually every 60 days. Data are stored on a SQL server at CUERE. The UMBC PAR sensor deployments are co-located with USGS stream gages at: Dead Run Franklintown (http://waterdata.usgs.gov/md/nwis/uv/?site_no=01589330), DR1 (http://waterdata.usgs.gov/md/nwis/uv?site_no=01589317), DR2 (http://waterdata.usgs.gov/md/nwis/uv?site_no=01589316), DR3 (http://waterdata.usgs.gov/md/nwis/uv?site_no=01589320), DR4 (http://waterdata.usgs.gov/md/nwis/uv?site_no=01589315), DR5 (http://waterdata.usgs.gov/md/nwis/uv?site_no=01589312).
