ecacfd: Consecutive frost days index per time period

In rcdo: Wrapper of 'CDO' Operators

Consecutive frost days index per time period

Description

Let infile be a time series of the daily minimum temperature TN, then the largest number of consecutive days where TN < 0 °C is counted. Note that TN have to be given in units of Kelvin. A further output variable is the number of frost periods of more than N days. The date information of a timestep in outfile is the date of the last contributing timestep in infile.

Usage

cdo_eca_cfd(ifile, N = NULL, ofile = NULL)

Arguments

ifile	String with the path to the input file.
N	INTEGER - Minimum number of days exceeded (default: N = 5)
ofile	String with the path to the output file.

Value

Operators that output one or more files return a character vector to the output files.

Operators that output an indefinite number of files return a string with the basename of the files.

Operatos that don't return filenames return a character vector with the string output.
