Summary of hand-held CT sampling events, weather conditions and resulting broad-sense heritabilities.

Date and time	Broad-sense heritability	Air temp. (°C)	Rel. humidity (%)	Wind speed (km/h)
18 October 2013	0.17	11.9 (09:00)	48.0 (09:00)	11.0 (09:00)
11:00 to 11:30
25 October 2013	0.13	17.8 (13:30)	28.0 (13:30)	17.0 (13:30)
13:50 to 14:20		19.0 (14:00)	28.0 (14:00)	17.0 (14:00)

Hand-held CT measurements were made on two occasions in 2013 on Treatment 2 only. In Treatment 2, irrigation was supplied to achieve the equivalent of a decile eight rainfall (wettest 20% of years) for the site. Treatment 2 comprised 348 plots. Values in parenthesis denote the time of day when air temperature, relative humidity, and wind speed were recorded. Note, that weather conditions were only recorded prior to the commencement of measurements on the 18th October 2013.
