Percentage of cold nights
Percentages of days with TN lower than the 10th percentile. The 10th percentile is computed based on the time scale selected (month, season or year) not daily as ETCCDI does. If you want to compute daily you can use RClimDex package.
tn10p(data, data_names = NULL, time.scale = YEAR, na.rm = FALSE)
data |
daily minimum temperature, Celsius |
data_names |
names of each period of time |
time.scale |
month, season or year |
na.rm |
logical. Should missing values (including NaN) be removed? |
percentage
cn = \frac{No. days TN < 10p} {No. days} * 100
data(data_all) tn10p(data=data_all$tn)
