This data consists of APSIM v7.10 model set ups and weather files used to simulate crop production under usual practice and in response to the 3 and/or 6 month seasonal climate forecasts at 8 different case study farms. Case studies were from individual farms in the grains (including cotton), sugarcane, and rice industries in Australia (farm managers deidentified). The model setups include any modified xml files to better represent crops and other modules). The weather files include historical records obtained from the SILO data base for the nearest weather station to the farms (modified by radiation sourced from Senaps data source), 'perfect' forecasts calculated from the historical record, and seasonal climate forecasts generated from the Access-S2 and ECMWF general circulation models.
