Delaware Water Gap National Recreation Area and Upper Delaware Scenic and Recreational River

The purpose of this report is to provide a concise weather and climate summary for the period from January 1 through December 31, 2009 and to place current patterns and trends in an appropriate historical and regional context (Knight et al., in preparation). It is the authors' intention that this report will satisfy an inherent interest in meteorological phenomena and meets a portion of the Eastern Rivers and Mountains Network (ERMN) Weather and Climate Monitoring objectives: - Document long-term trends in weather and climate through seasonal and annual summaries of selected parameters (e.g., multiple forms of precipitation, temperature). - Identify and document extremes and averages of climatic conditions for common parameters (e.g., precipitation, air temperature) and other parameters where sufficient data are available (e.g., wind speed and direction, solar radiation). - Provide information on near real-time weather parameters, historical climate patterns, and climate station metadata from a single, easy-to-use Internet portal.
