^atmdX, mean of the average daily temperatures (°C) in the period between the day of sampling collection (SC) and day X prior to SC; ti2, minimum daily temperature (°C) on day 2 prior to SC; tidX, mean of the minimum daily temperatures (°C) between the day of SC and day X prior to SC; tx3, maximum daily temperature (°C) on day 3 prior to SC; txdX, mean of the maximum daily temperatures (°C) between the day of SC and day X prior to SC; ws2, wind speed on day 2 prior to SC; pdX, mean amount of rain (mm) between the day of SC and day X prior to SC.

^bBoldface indicates the highest component loading a variable has in the particular model part.
