Monthly statistics

This module computes statistical values over timesteps of the same month. Depending on the chosen operator the minimum, maximum, range, sum, average, variance or standard deviation of timesteps of the same month is written to outfile. The time of outfile is determined by the time in the middle of all contributing timesteps of infile. This can be change with the CDO option –timestat_date <first|middle|last>.

Usage

cdo_monavg(ifile, complete_only = NULL, ofile = NULL)

cdo_monmax(ifile, complete_only = NULL, ofile = NULL)

cdo_monmean(ifile, complete_only = NULL, ofile = NULL)

cdo_monmin(ifile, complete_only = NULL, ofile = NULL)

cdo_monrange(ifile, complete_only = NULL, ofile = NULL)

cdo_monstd(ifile, complete_only = NULL, ofile = NULL)

cdo_monstd1(ifile, complete_only = NULL, ofile = NULL)

cdo_monsum(ifile, complete_only = NULL, ofile = NULL)

cdo_monvar(ifile, complete_only = NULL, ofile = NULL)

cdo_monvar1(ifile, complete_only = NULL, ofile = NULL)

Arguments

ifile

String with the path to the input file.

complete_only

BOOL - Process the last month only if it is complete

ofile

String with the path to the output file.

Details

monmin    Monthly minimum
          For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = min\{i(t',x), t_1<t'<=t_n\}
monmax    Monthly maximum
          For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = max\{i(t',x), t_1<t'<=t_n\}
monrange  Monthly range
          For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = range\{i(t',x), t_1<t'<=t_n\}
monsum    Monthly sum
          For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = sum\{i(t',x), t_1<t'<=t_n\}
monmean   Monthly mean
          For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = mean\{i(t',x), t_1<t'<=t_n\}
monavg    Monthly average
          For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = avg\{i(t',x), t_1<t'<=t_n\}
monstd    Monthly standard deviation
          Normalize by n. For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = std\{i(t',x), t_1 < t' <= t_n\}
monstd1   Monthly standard deviation (n-1)
          Normalize by (n-1). For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = std1\{i(t',x), t_1 < t' <= t_n\}
monvar    Monthly variance
          Normalize by n. For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = var\{i(t',x), t_1 < t' <= t_n\}
monvar1   Monthly variance (n-1)
          Normalize by (n-1). For every adjacent sequence t_1, ...,t_n of timesteps of the same month it is:

          o(t,x) = var1\{i(t',x), t_1 < t' <= t_n\}
