Quality

Monthly mean lower stratospheric temperatures are calculated from daily observations of temperature at the 100hPa level. Observations are restricted to within a few hours of 0000UTC to avoid biases and to allow comparison with limited historical data. If less than 25 daily observations are available for a given month, the monthly data are flagged and removed from the State of Environment dataset. The monthly lower stratospheric air temperature anomaly is calculated as the difference between the mean lower stratospheric air temperature for a given month and the long-term mean lower stratospheric air temperature for that calendar month between 1971 and 2000, so that: Anomaly (for given month) = Value (for given month) - Long-term Mean (for relevant calendar month) Although the Bureau of Meteorology uses the period from 1961 to 1990 as the standard period for calculation of long-term means, it was decided that for Antarctic stations, the 1971-2000 dataset was in most cases more complete, and would therefore provide a more accurate long-term mean. These records require analysis for variability and trends. However, there are likely to be significant errors in the data, and these need to be addressed first (see Research Issues). The data are subject to a number of quality checks, although these will not prevent errors: - The radiosonde checks the reasonableness of raw values from the probes whilst converting to temperature. - The receiving station applies reasonableness checks, generally with the involvement of a human observer.
