The next three digits in the group ""017"" give the temperature in degrees and tenths of a degree Celsius, _01.7 °C (28.9 °F). The last four digits ""1017"" indicate the dew point, _01.7 °C (28.9 °F). Note: ASOS software, as of this update, uses whole degrees in °F to compute the °C values in this group."
