two_sites

A dataset containing daily weather data in APSIM format for
Site_1: at -27 S, 151 E and Site_2: -28 S, 152 E for the period 1
to 5 Nov 2020

datasets

Calculate agrometeorological variables for crops
including growing degree days (McMaster, GS & Wilhelm, WW
(1997) <doi:10.1016/S0168-1923(97)00027-0>), cumulative
rainfall, number of stress days and cumulative or mean
radiation and evaporation. Convert dates to day of year
and vice versa. Also, download curated and interpolated
Australian weather data from the Queensland Government
DES longpaddock website
