The National Oceanic and Atmospheric Administration (NOAA) compiles and presents a vast amount of weather information. Unfortunately, specific data is often difficult to find and use in energy analysis. Some of the most commonly used data has been compiled into useful formats and is presented here.

Degree Day Data

    Full year NOAA Monthly Degree Day data has been placed in spreadsheets to facilitate its use in energy analysis. This data may be downloaded as either XLS or PDF files by clicking the appropriate link in the following table:

    Note:  The NOAA indicates that the degree days computed for Jan 12 to April 26 (2008) and for August 20 to October 31 (2009) were erroneous due to corrupted temperature grids. The data was re-run and the following files were updated on July 2, 2008 with the corrected values as posted by the NOAA.
