Hourly air temperature in degrees Fahrenheit and associated three-digit data-source flag, January 1, 1948 - September 30, 2017
Description
The text file "Air temperature.txt" contains hourly data and associated data-source flag from January 1, 1948, to September 30, 2017. The primary source of the data is Argonne National Laboratory (Argonne National Laboratory, 2017) and is processed following the guidelines documented in Over and others (2010). Missing and apparently erroneous data values were replaced with adjusted values from nearby stations used as “backup”. The Illinois Climate Network (Water and Atmospheric Resources Monitoring Program, 2015) station at St. Charles, Illinois is used as "backup". Each data source flag is of the form "xyz" that allows the user to determine its source and the methods used to process the data (Over and others, 2010).
