** 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.
