Description Usage Arguments Details Value Author(s) Examples

Creates climate mean monthly values from a monthly series of temperature and precipitation.

1	climate(series, first.yr = NULL, last.yr = NULL, max.perc.missing)

`series`	the monthly series of temperature and precipitation.
`first.yr`	first year of the period over which climatology is calculated
`last.yr`	last year of the period over which climatology is calculated
`max.perc.missing`	maximum acceptable percentage of missing data in the averaging period from `first.yr` to `last.yr` (0-99).

series is a data frame with years, months, temperature (and precipitation) values. Names in series columns must include: year, month, Tn and Tx (minimum and maximum temperatures, respectively) or, as an alternative, Tm (mean temperatures).

If first.yr or last.yr are NULL (default), the lowest and highest values in series are taken as the period.

A data frame with climatic monthly values of: precipitation, minimum and maximum temperatures (if existing in series), mean temperature (either averaged from existing values in series, or calculated by the function as (Tn + Tx)/2), absolute minimum monthly temperature.
