Air temperature and light intensity measurements within and near the Coweeta basin from 2011 to 2013

In this study 50 HOBO data loggers were deployed at 61 locations within and near the Coweeta basin to record air temperature and light intensity observations. The loggers were deployed between April 2011 and April 2012. The duration of observation at each location varied. All loggers were removed by February 2013. In April 2012, radiation shields constructed of two inverted plastic funnels were added to a subset of loggers in an attempt to reduce the effect of solar radiation on daytime temperature observations. Light intensity data collected by the loggers were used as a means of flagging potentially erroneous observations when the logger was exposed to direct sunlight. A light intensity threshold above which observations were flagged was determined by comparing logger observations to those collected by nearby (<5m) sensors protected with commercial gill style radiation shields. Despite attempts to flag potentially erroneous daytime temperature observations, it is likely that errors remain and these data should be used accordingly.
