Data from SILO is used by APSIM to simulate the daily cycle of soil temperature. A 73 year record (1950 : present) is used to estimate the distribution of surface (0-150mm) minimum soil temperature during each spring.
The chance of a frost damaging the crop is estimated by counting the number of times air temperature goes below 0 oC during the 73 year period. The crop is considered vulnerable after seven leaves have emerged, a duration that varies with average air temperature - colder temperatures lengthen leaf appearance.
The distribution is presented as a box plot, where the 25th and 75th percentiles are marked as a box, and the center mark is the median (50th). The whiskers of each box are the 5th and 95th percentiles.
