Model results: Model-based decision support for the choice of active spring frost protection measures in apple production

Background:

Apple producers are dealing with weather related risks affecting their production. One important risk, is the damage of buds or young fruits by late spring frosts. Fruit growers can protect their apple orchards against this risk in various ways. With a probabilistic model (available on Git Hub: https://github.com/ChristineSchmitz/Supporting_Information_DA_Frost_Protection, https://doi.org/10.5281/zenodo.11473204), we want to support the decision between several active frost protection measures. The measures considered in the model are: overhead irrigation, below-canopy irrigation, stationary wind machines, mobile wind machines, tractor-mounted gas heaters, portable gas heaters, candles and pellet heaters.

As case studies, we parameterized the model for two German apple production regions (Rhineland and Lake Constance region).

Repository content:

This repository contains the simulation results of 100,000 Monte Carlo runs with the model.

The results are provided as .RDS and .csv files. The .RDS files are suitable to be uses with the Code on Git Hub to follow the Post-Hoc analysis and figure plotting.
