Summer days index per time period

Let infile be a time series of the daily maximum temperature TX, then the number of days where TX > T is counted. The number T is an optional parameter with default T = 25°C. Note that TX have to be given in units of Kelvin, whereas T have to be given in degrees Celsius. Parameter is a comma-separated list of \"key=values\" pairs.

Usage

cdo_eca_su(ifile, T = NULL, freq = NULL, ofile = NULL)

cdo_etccdi_su(ifile, T = NULL, freq = NULL, ofile = NULL)

Arguments

ifile

String with the path to the input file.

T

FLOAT - Temperature threshold (unit: °C; default: T = 25°C)

freq

STRING - Output frequency (year, month)

ofile

String with the path to the output file.

Details

eca_su     Summer 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_su  Summer 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.
