Let infile be a time series of the daily minimum temperature TN, then the number of days where TN > T is counted. The number T is an optional parameter with default T = 20°C. Note that TN 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_tr(ifile, T = NULL, freq = NULL, ofile = NULL)
cdo_etccdi_tr(ifile, T = NULL, freq = NULL, ofile = NULL)
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.

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.
