AWS summaries – Summer

Narrung – Period September 3, 2022 – December 4, 2022 compared to same period in 2021

Total rainfall for the period was 201 mm contrasting with 96.8 mm in the same period in 2021. The averaged daily temperature was 14.36 deg C largely the same as the 14.27 deg C received in 2021. Relative humidity averaged 75.06% in the 2022 period largely the same as the average of 69.28% received in the corresponding period in 2021. Soil temperature averages at 15 cm averaged 17.94 deg C compared to 18.26 deg C in the same period in 2021. Growing degree days (T base 10) averaged at 4.60 units per day in the period in 2022 was largely the same as the 4.62 units per day average in the corresponding 2021 period. Observing global solar radiation inputs in the 2022 period saw an averaged 231 W/m2/unit period/day with a 250.6 W/m2/unit period/day in the 2021 period. Marginally lower averaged daily wind-speeds in the 2022 period (11.58 km/h) compared to the higher average in the 2021 period of 11.77 km/h. Reference crop evapotranspiration calculated at the site also produced an averaged lower daily rate of 3.38 mm/day in the 2022 period compared to 3.76 mm/day in 2021. Frost hours were nil across both periods.

Mt. Pleasant – Period September 3, 2022 – December 4, 2022 compared to same period in 2021

Relative humidity averaged 80.29% in the 2022 period somewhat higher than the average of 72.35% received in the corresponding period in 2021. Soil temperature averages at 15 cm averaged 13.64 deg C compared to 14.42 deg C in the same period in 2021. Growing degree days (T base 10) averaged at 2.61 units per day in the period in 2022 was lower than the 3.08 units per day average in the corresponding 2021 period. Observing global solar radiation inputs in the 2022 period saw an averaged 214 W/m2/unit period/day with a 238.6 W/m2/unit period/day in the 2021 period. Marginally lower averaged daily wind-speeds in the 2022 period (13.8 km/h) compared to the higher average in the 2021 period of 14.49 km/h. Reference crop evapotranspiration calculated at the site also produced an averaged lower daily rate of 2.81 mm/day in the 2022 period compared to 3.48 mm/day in 2021. Frost hours were nil across both periods.
