r4123 r4132 852 852 The observation files and settings understood by \textbf{namobs} have been outlined in the online 853 853 obs oper section. In addition there are two further namelists wich control the operation of the offline 854 obs oper. \textbf{namo ff} which controls the input model fields and \textbf{namcl4} which controls the854 obs oper. \textbf{namooo} which controls the input model fields and \textbf{namcl4} which controls the 855 855 production of class 4 files. 856 856 … … 863 863 \textbf{votemper}, \textbf{vosaline} and optionally \textbf{sshn} present. 864 864 865 For each field read there must be an entry in the \textbf{namo ff} namelist specifying the865 For each field read there must be an entry in the \textbf{namooo} namelist specifying the 866 866 name of the file to read and the index along the \emph{time\_counter}. For example, to 867 867 read the second time counter from a single file the namelist would be. … … 871 871 \begin{verbatim} 872 872 !---------------------------------------------------------------------- 873 ! namo ffOffline obs_oper namelist873 ! namooo Offline obs_oper namelist 874 874 !---------------------------------------------------------------------- 875 875 ! ooo_files specifies the files containing the model counterpart 876 876 ! nn_ooo_idx specifies the time_counter index within the model file 877 &namo ff877 &namooo 878 878 ooo_files = "foo.nc" 879 879 nn_ooo_idx = 2 … … 892 892 \begin{verbatim} 893 893 !---------------------------------------------------------------------- 894 ! namo ffOffline obs_oper namelist894 ! namooo Offline obs_oper namelist 895 895 !---------------------------------------------------------------------- 896 896 ! ooo_files specifies the files containing the model counterpart 897 897 ! nn_ooo_idx specifies the time_counter index within the model file 898 898 ! nn_ooo_freq specifies number of time steps between read operations 899 &namo ff899 &namooo 900 900 ooo_files = "foo.nc" "foo.nc" 901 901 nn_ooo_idx = 1 2 … … 915 915 at different indices can be combined at a particular frequency in time to 916 916 generate a pseudo model evolution.
