Hello to everyone,<br><br>I have problem to concatenate the whole years from 1995 to 2005 into one ctl file.<br><br>The script which i am using to concatenate these years is given below;<br><br><b>cdo cat year1995,year1996,year1997...............,year2005</b><br><br><b>before these commands, i used the above command</b><br><br>cdo dv2uv echam_yearout9508 echam_yearout9508_dv2uv.grb <b>[To change it from divergence and vorticity to horizontal wind u,v] </b><br><br>cdo selcode,130,131,132,133,134,142,144,147,157,182,223 echam_yearout9508_dv2uv.grb echam_yearout9508_dv2uv_TUVP.grb <b>[To include the variables generated by the model].</b><br><br>cdo sp2gp echam_yearout9508_dv2uv_TUVP.grb echam_yearout9508_dv2uv_TUVP_grid.grb <b>[Change from Spectral to gridpoint]</b><br><br>cdo ml2pl,100000,80000,50000,20000,10000 echam_yearout9508_dv2uv_TUVP_grid.grb echam_yearout9508_dv2uv_TUVP_grid_press.grb <b>[To Include the Pressure Level before this it was using the hybrid level]<br><br></b>cdo gradsdes2 echam_yearout9508_dv2uv_TUVP_grid_press.grb <b>[To create the ctl file]</b><br><br>And this cdo stuff then generated the ctl file which looks much perfect however as i opened it. It only showed my the 1995:01:01 to last time step 1995:12:31<br><br>I then changed the tdef in the ctl file by using the text editor, instead of this it does not work.

In the initial<br>implementation, the time(s) that are in each file are indicated by the file name.<br>An example of this might be hourly data, where each 24 hours has been placed in a separate file.<br>Each file is named this way:<br>1may92.dat<br>2may92.dat<br>etc.<br>You indicate to GrADS that there are multiple files in this time series by giving a substitution<br>template as the file name:<br><br><b>dset %d1%mc%y2.dat [Where should i have to write this command and will it works then for ctl file as well]</b><br><br><b>What more things i have to include in this script as i simulated the 6 hourly data??</b><br><br><br>and giving an options record that looks like:<br>100<br>options template<br>and specifying the time range and increment in the tdef record:<br>tdef 72 linear 0z1may1993 1hr<br>GrADS will figure out automatically that there are 24 times in each file, and what file names<br>correspond to what times. As you display data, GrADS will only open one file at a time. As you<br>change times such that another file is referred to, the open file is closed, and the new file is opened.<br>Valid substitutions are:<br><br><b>%y2 - 2 digit year (last 2 digits)<br>%y4 - 4 digit year<br>%m1 - 1 or 2 digit month<br>%m2 - 2 digit month (leading zero if needed)<br>%mc - 3 character month abbreviation<br>%d1 - 1 or 2 digit day<br>%d2 - 2 digit day<br>%h1 - 1 or 2 digit hour<br>%h2 - 2 digit hour<br>%h3 - 3 digit hour (e.g., 120 or 012)<br>%f2 - 2 or 3 digit forecast hour<br>%f3 - 3 digit forecast hour<br>%n2 - 2 digit minute (leading zero if needed)<br>for specifying the initial time (e.g., NWP model output from NMC and FNMOC)<br>%iy2 - initial 2 digit year (last 2 digits)<br>%iy4 - initial 4 digit year<br>%im1 - initial 1 or 2 digit month<br>%im2 - initial 2 digit month (leading zero if needed)<br>%in2 - initial 2 minute (leading zero if needed)<br>%imc - initial 3 character month abbreviation<br>%id1 - initial 1 or 2 digit day<br>%id2 - initial 2 digit day<br>%ih1 - initial 1 or 2 digit hour<br>%ih2 - initial 2 digit hour<br>%ih3 - initial 3 digit hour<br>(time increment must be hours)</b><br>This support works on all supported GrADS data types (GrADS gridded, GRIB, GrADS station<br>data). If you specify file format options, the options must apply equally to each file.<br>The real-time data on DECstations makes use of this new feature.
