Which group represents the value for minimum temperature over the last 24 hours?

The value for minimum temperature over the last 24 hours in a METAR report is typically represented by the group that follows the 6-character group indicating the station identifier and preceding any significant weather details. The group “400561007” signifies specific meteorological information - the first two digits (40) represent tenths of degrees Celsius, while the subsequent digits indicate the minimum temperature observed (i.e., 5.1 degrees Celsius). This format is consistent with reporting minimum temperatures as part of standard meteorological observations. Understanding this structure is essential for accurate interpretation of METAR reports, as it allows meteorologists and other users to assess temperature variations effectively over the specified period.
