Ice days index per time period

Let infile be a time series of the daily maximum temperature TX, then the number of days where TX < 0 °C is counted. Note that TX have to be given in units of Kelvin. Parameter is a comma-separated list of \"key=values\" pairs.

Usage

cdo_eca_id(ifile, freq = NULL, ofile = NULL)

cdo_etccdi_id(ifile, freq = NULL, ofile = NULL)

Arguments

ifile

String with the path to the input file.

freq

STRING - Output frequency (year, month)

ofile

String with the path to the output file.

Details

eca_id     Ice days index per time period
           The operator counts over the entire time series.
           The date information of a timestep in outfile is the date of
           the last contributing timestep in infile.
etccdi_id  Ice days index per time period
           The default output frequency is yearly.
           The date information of a timestep in outfile is the mid of
           the frequency interval.
