Vegetation End Method "NuskeAlbert"
Description
The method NuskeAlbert
provides a very simple method which is inspired by
standard climatological procedures but employs a 7 day moving average and
a 5 °C threshold (cf. Walther and Linderholm 2006).
Calculations
2 criteria: temperature & short day criterion
Temperature criterion
7 day moving average of daily mean temperatures end if 5 consecutive days under under 5° C start the search at 1st of July / vegetation start
Short day criterion
last day of the vegetation period is 5th of October
