| Abstract |
Average annual temperatures (maximum, minimum or mean) are calculated by adding daily temperature values each year, dividing by the number of days in that year to get an average for that particular year. The average values for each year in a specified period (1961 to 1990) are added together and the final value is calculated by dividing by the number of years in the period (30 years in this case). Similarly, average monthly temperatures are calculated by adding monthly temperature averages (from daily data) and dividing by the number of years in the specified period. Mean temperatures are calculated by adding the daily maximum temperature and the daily minimum temperature, and dividing by two. Grids are at a resolution of 0.025 degrees.

| Abstract | A monthly average is calculated using 30 years of monthly gridded rainfall data between 1981 and 2010. These monthly averages are used to calculate annual averages. More information is available on the BoM website http://www.bom.gov.au/jsp/ncc/climate_averages/rainfall/index.jsp |

| Abstract |
Annual total heating degree days (count, 18C reference temperature), 1961-1990 Mean monthly and mean annual heating & cooling degree days grids. The grids show the heating & cooling degree days values across Australia in the form of a two-dimensional array. The mean data are based on the standard 30-year period 1961-1990. Heating and cooling degree days are based on the average daily temperature. The average daily temperature is calculated as follows: [maximum daily temperature + minimum daily temperature] / 2. If the average daily temperature falls below comfort levels, heating is required; and if it is above comfort levels, cooling is required. The heating degree days or cooling degree days are determined by the difference between the average daily temperature and the comfort level temperature. The comfort level values used are 12 and 18 degrees Celsius for heating and 18 and 24 degrees Celsius for cooling. For example, if heating is being considered to a temperature comfort level of 18 degrees, and the average daily temperature for a particular location was 14 degrees, then heating equivalent to 4 degrees (4 heating degree days) would be required to maintain a temperature of 18 degrees for that day. However if the average daily temperature was 20 degrees then no heating would be required, so the number of heating degree days for that day would be zero. If cooling is being considered to a temperature comfort level of 24 degrees, and if the average temperature for a day was 27 degrees, then cooling equivalent to 3 degrees (3 cooling degree days) would be required to maintain a temperature of 24 degrees for that day. However if the average temperature was 21 degrees, then no cooling would be required, so the number of cooling degree days for that day would be zero. Average annual heating and cooling degree days are calculated by adding heating and cooling degree days totals over a specified period (1961 to 1990) and dividing by the number of years in that period (30 years in this case). Similarly, average monthly heating and cooling degree days are calculated by adding monthly totals and dividing by the number of years in the specified period.

| Abstract | These maps show the average annual and average monthly (9am and) 3pm relative humidity (RH) over the period 1976 to 2005. Average annual RH is calculated by adding (9am or) 3pm RH values over a specified period (1976 - 2005) and dividing by the number of years in that period (30 years in this case). Similarly, average monthly (9am and) 3pm RH is calculated by adding daily (9am or) 3pm values for a selected month and dividing by the number of years in the specified period. Relative humidity (RH) is an indicator of the moisture content of the air. It is the amount of moisture in the air as a percentage of the amount of moisture the air can contain. Warmer air can contain more moisture than cooler air, which means that for a given amount of atmospheric moisture, RH will be lower if the air is warm and higher if the air is cool. This can be seen by comparing the daily 9am maps (higher RH values) with the daily 3pm maps (lower RH values) for any month of the year. The annual 9am and 3pm RH maps show that RH increases in coastal regions, similar in nature to the distribution of rainfall in the annual rainfall maps. RH tends to be higher in northern Australia due to the wet climate experienced in this region.
