Let infile be a time series of the daily precipitation amount RR in [mm] (or alternatively in [kg m-2]), then the number of days where RR is at least x mm is counted. eca_r10mm and eca_r20mm are specific ECA operators with a daily precipitation amount of 10 and 20 mm respectively. The date information of a timestep in outfile is the date of the last contributing timestep in infile except for the etccdi operator. Parameter is a comma-separated list of "key=values" pairs.
cdo_eca_pd(ifile, x = NULL, freq = NULL, ofile = NULL)cdo_eca_r10mm(ifile, x = NULL, freq = NULL, ofile = NULL)
cdo_eca_r20mm(ifile, x = NULL, freq = NULL, ofile = NULL)
cdo_etccdi_r1mm(ifile, x = NULL, freq = NULL, ofile = NULL)
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.
String with the path to the input file.
FLOAT - Daily precipitation amount threshold in [mm]
STRING - Output frequency (year, month)
String with the path to the output file.
eca_pd Precipitation days index per time period
Generic ECA operator with daily precipitation sum exceeding x mm.
eca_r10mm Heavy precipitation days index per time period
Specific ECA operator with daily precipitation sum exceeding 10 mm.
eca_r20mm Very heavy precipitation days index per time period
Specific ECA operator with daily precipitation sum exceeding 20 mm.
etccdi_r1mm Precipitation 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.
