Reduction in evaporation due to the bird screen used in the Australian class A pan evaporation network

Key Points

• The aim is to determine the effect of bird screens on evaporation measurements in class A pans across multiple locations.
• Measured evaporation at four different locations fitted with bird screens.
• Calculated monthly evaporation totals from screened pans.
• Averaged results show a seven percent correction is needed for evaporation totals from the screened pans.
