BOM have no logical explanation of their mystery algorithms which may or may not be applied to various location temperature measurements. Their common explanation is the measurement site probably moved during any questioned time but then they can`t give the exact date and new location of the move. This is embarrassing for Australia that our well funded BOM , a strident supporter of global warming, can`t succinctly explain their raw data changes that enhance warming trends. Billions of co2 abatement measures in wind and solar power have hung on their figures as well as the rich salaries of people such as Tim Flannery.
