Column, Explanation -------------------------------------------------------------------- 1 Product code 2 Bureau of Meteorology station number 3 Year 4 Month 5 Day 6 Daily minimum temperature (degrees Celsius) 7 Period over which daily minimum temperature was measured (days) 8 Quality of daily minimum temperature ** Important notes ** 1) QUALITY FLAG DESCRIPTIONS Y: completed quality control and acceptable N: not yet completed quality control process or date uncertain, quality not assured Climate data pass through a number of stages in quality control which occurs over a period of time. Data are only included in this product if either one of the following is true: i) If the Quality Flag = Y, then the data have completed the normal quality control process and we do not believe them to be suspect or wrong; ii) If the Quality Flag = N, then no significant errors have yet been detected, although this may change during a later stage of the quality control process. This also appplies if the data have completed the normal quality control process but there is some uncertainty about the date on which the temperature occured. 2) GAPS AND MISSING DATA Very few stations have a complete unbroken record of climate information. A station may have been closed, re-opened, upgraded to a full weather station or downgraded to a rainfall only station during its existence, resulting in breaks in the record for some or all elements. It is important to note that damaged instrumentation can result in gaps in the record for one (or more) meteorological element. In contrast the absence or illness of an observer may result in gaps in the record for all elements at a particular site. 3) INSTRUMENTS AND OBSERVATIONAL PRACTICES Historically, if an observational site moved a relatively short distance (within about 1 to 2 km) it may have continued to use the same station number. Changes may have occurred in instrumentation and/or observing practices over the period included in a dataset, which may have an effect on the long-term record. Observations of temperature at some (but not all) locations prior to 1910 may have been made with non-standard equipment. In recent years many stations have had observers replaced by automatic weather stations (AWSs), either completely or at certain times of the day. 4) LATITUDES AND LONGITUDES Latitudes and longitudes are provided to 2 decimal places. However, in many cases the geographic coordinates of a station will not be accurate to 2 decimal places. More precise positioning may be available upon request (see contact details). 5) TIME For a part of the year some Australian States adopt Daylight Savings Time (DST). The changeover dates vary from State to State and year to year. More information can be found at: http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml The majority of maximum and minimum temperature data have been recorded at 9am local time. The minimum temperature measured at that time is recorded against the day on which it was measured, while the maximum temperature is recorded against the previous day. 6) COPYRIGHT The copyright for any data is held in the Commonwealth of Australia and the purchaser shall give acknowledgement of the source in reference to the data. Apart from dealings under the copyright Act, 1968, the purchaser shall not reproduce, modify or supply (by sale or otherwise) these data without written permission. 7) LIABILITY While every effort is made to supply the best data available this may not be possible in all cases. We do not give any warranty, nor accept any liability in relation to the information given, except that liability (if any), that is required by law. 8) CONTACT DETAILS If you need more information, you can contact us via the Climate Data & Information links at: http://www.bom.gov.au/climate/how/contacts.shtml _________________________________________ Created on Tue 26 Jul 2022 04:16:31 AM GMT-00:00 from Climate Data Online, Bureau of Meteorology. http://www.bom.gov.au/climate/data Further information on this product: http://www.bom.gov.au/climate/cdo/about/about-airtemp-data.shtml
