Data copyright Ferny Grove Weather 2020, Produced 9/02/2020. Data checking has been carried out but errors may still be present and therefore there is no assurance of correctness. Corrections may be made at a later data if errors or deficiencies are found and/or improvements in data handling techniques are made, though data with major improvements may not be updated. Data measured with low accuracy equipment, mostly replaced with professional moderate accuracy equipment from October 5 except for daily rainfall which is measured using non-professional equipment with moderate accuracy.
Site commencement data is April 15 2009 except for daily rainfall which commenced on January 1 1987. Not all variables have been measured over the entire station record. Most variables are measured over a 24 hour period ending in the evening and effective October 5 this is the 24 hours from midnight. Maximum temperatures are measured over the 24 hours from 9 am on the day of measurement. Minimum temperatures are measured over the 24 hours to 9 am of the day of measurement. This is same to the official time standards and measured in degrees C. Rainfall is measured over 24 hours to 9am and recorded on that day. This is the same as the official time standard and measured in millimetres. Some rainfall measurements are not made at 9am and is adjusted based on the automatic record. Minimum Grass Temperature is measured over an approx. 12 hour period ending in the early morning. MSL refers to Mean Sea Level, which is the standard meteorological method of measuring air pressure reduced to sea level based on both elevation and temperature. Grass Minimum Depression is the difference of the grass minimum temperature from the air temperatures and is a positive value when the grass temperature is below the air temperature.
Dew Point, Average Wind Speed, Dominant Wind Direction, Wind Run, Rain Rate and Hourly Rain are measured automatically over a 24 hour period starting at midnight and recorded for that day. This started on the 6 October 2011. Until replaced from 5 October temperature and humidity sensor is under exposed so minimum temperature and maximum humidity are incorrect and low accuracy rain gauge is used which are not used as the site’s official record. This data limitation does not apply to other measurements of temperatures, air pressure and humidity, wind gust, daily and monthly rainfall and rain days elsewhere in this summary which are recorded separately and form the official record for this site. The replacement equipment is sited in more exposed locations and therefore the limitations don’t apply, though the automatic daily rainfall doesn’t form the official data for the site. However the automatic record for some data may be used if data is not available/ not suitable.
Long term averages are based on all available long period past measurements. Long term average for Temperature, Relative Humidity and Air pressure is based on 2009 to 2015 average from the station record and wind speed is based on the 2010 to 2018 average from station record. Long term average for rainfall is based on 1987 to 2017 average from the station record. The Fraction of monthly average expresses how much has fallen in respect to the long term average listed as a percentage.
