Description

The Modified Nesterov Index (MNI) reflects the relationship between observed weather conditions and fire occurrence. It is a cumulative index computed from daily temperature and dewpoint temperature, which is reset when a certain precipitation value is reached.

Usage

mni(dew_point, taverage, rh, pr, data_names = NULL, time.scale = YEAR,
  na.rm = FALSE)

Arguments

dew_point

dew point

taverage

medium temperature

rh

relative humidity

pr

precipitation

data_names

names of each period of time

time.scale

month, season or year

na.rm

logical. Should missing values (including NaN) be removed?

Value

MNI
