Description: Predicts the occurrence times (in day-of-year) of spring
        phenological events. Three methods, including the accumulated
        degree days (ADD) method, the accumulated days transferred to a
        standardized temperature (ADTS) method, and the accumulated
        developmental progress (ADP) method, were used. See Shi et al.
        (2017a) <doi:10.1016/j.agrformet.2017.04.001> and Shi et al.
        (2017b) <doi:10.1093/aesa/sax063> for details.
