# tmp\_min\_sd

This parameter quantifies the variability in minimum temperature for each month. The standard deviation is calculated as

$$
σmn\_{mon}=\sqrt{(\frac{∑*{d=1}^N\*(T*{mn,mon}-μmn\_{mon} )^2 }{N-1}})
$$

where $$σmn\_{mon}$$is the standard deviation for daily minimum temperature in month $$mon$$ (ºC), $$T\_{mn,mon}$$ is the daily minimum temperature on day $$d$$ in month $$mon$$ (ºC), $$μmn\_{mon}$$ is the average daily minimum temperature for the month $$mon$$ (ºC), and $$N$$ is the total number of daily minimum temperature records for month $$mon$$.
