This historical legacy dataset depicts the 50-year mean annual rainfall isoheyts (contours) over Queensland for the period 1920 to 1969. The dataset was a project activity, and produced from the mean annual rainfall of as many locations as possible including private collections. Incomplete datasets were made whole by calculating values for missing periods through correlation with adjacent rainfall stations.
