Report / Physics and Engineering LaboratorySummary: A comprehensive series of atmospheric measurements was made at Roxburgh from mid-August to mid-October 1981. Artificial fog was generated on several occasions, to assess its use for combatting frost. Experimental details and results are presented in this report. It is concluded that artificial fog, along with other methods relying on either a well-developed atmospheric temperature inversion or low wind drift, is unlikely to be a reliable method for fighting Spring frosts at Roxburgh. An efficient overtree sprinkling system offers the best protection against frost damage. Further research should be directed towards the development of an alternative sprinkler system, more suited to the newer orchard methods being established in Central Otago.
