Post subject: | missing ancillary files -- how to get them & which ones |
Hi Peter at Tanzania Met Agency, I am sorry that the master ancillaries were left off from the input data hard drive we sent you. This was a mistake on our part. I will bring them to Dar with me along with any other boundary data you need. If you want to start a test experiment, you can download the corresponding set of missing ancillaries here: http://www.precisrcm.com/ancil/master/ The exact ancillary files (which are the surface and atmospheric boundary conditions for the regional model) are containing in configuration files in $UMDIR/vn4.5/ctldata/ancil_config/[GCM RUNID] For example, the config file for addfa (HadAM3P baseline 1960-1990), can be viewed this way: Code: cd $HOME . setvars cat $UMDIR/vn4.5/ctldata/ancil_config/addfa which yields: Code: ----------- # Master ancillary source # Set to the name of the master ancillary file to be used for each type. # It is assumed that master anciilaries live in directory $ANCIL_MASTER #----------------------------------------------------------------------- source_mask = qrfrac.navy10_BAS source_orog = qrorog.navy10.y84n source_rough = qrparm.ashhr source_vegsoil = qrparm.whs source_whs = qrparm.whs source_igbp = qrdata.igbp source_soil = qrdata.soil source_soilcarbon = qrparm.soilcarbon source_sst = sst.addfa source_sice = sice.addfa source_ozone = ozone.historical.SRES.360 source_so2dms = so2dms.historical.SRES.360 source_oxi = oxi.addfa source_volc = volc.addfa #---------------------------------------------------------------------- # The types of ancilliary which need periodic updating. # E.g. update_types = # E.g. update_types = ozone, sst, sice #---------------------------------------------------------------------- update_types =ozone #---------------------------------------------------------------------- # End of file #---------------------------------------------------------------------- All of the files starting with qr* are already installed with PRECIS 2.0 beta. You need to download the other six sets of files from the website URL. They are not huge files and I think you can manage to get them. Where it says "update_types" these are the files which there are more than one file. There are four ozone files in fact. All in all here are the files you need to download http://www.precisrcm.com/ancil/master/sst.addfa.gz http://www.precisrcm.com/ancil/master/sice.addfa.gz http://www.precisrcm.com/ancil/master/ozone.historical.SRES.360.f9c10.gz http://www.precisrcm.com/ancil/master/ozone.historical.SRES.360.g9c10.gz http://www.precisrcm.com/ancil/master/ozone.historical.SRES.360.h9c10.gz http://www.precisrcm.com/ancil/master/ozone.historical.SRES.360.i9c10.gz http://www.precisrcm.com/ancil/master/so2dms.historical.SRES.360.gz http://www.precisrcm.com/ancil/master/oxi.addfa.gz http://www.precisrcm.com/ancil/master/volc.addfa.gz Download those files to the directory location set in $ANCIL_MASTER which you can see by typing Code: cd $HOME . setvars echo $ANCIL_MASTER The files need to be unzipped! Code: cd $ANCIL_MASTER gunzip -v *.gz Assuming you have addfa boundary data in $PP4LBCDIR/addfa/ and the start dumps (i.e. initial conditions) in $DUMPSDIR, you should now see addfa as a valid option for input GCM in the PRECIS user interface. Refer to the technical manual information on setvars (where the input data needs to be) for more information. Or reply to this comment. Thanks David |
