Hi Patrick.. You will very likely get a more robust response from Steve Chiswell or someone who really knows what they are doing - but in the meantime - I belive NIDS files should be ready to read by GEMPAK. Try the gpmap program - set your map=1, garea=dset, proj="", radfile=maple_cmp_fcst_200708082145_200708082215.mos, dev=xw|test|.6;.6 and run the program. If it displays it works, if not, you may need to convert this to a different format or use a differnet gempak program to plot the data that I am unfamiliar with. Regarding your second question - there are no tools to take a current snapshot of the atmosphere in gridded form and "prog" it into the future - even by simple advection. GEMPAK is a display tool only - no dynamical or even simple methods to step a current state of the atmosphere into the future. Although - THAT would be cool. You may want to consider using the workstation WRF to help with this exercise. This is a workstation version of WRF. See http://strc.comet.ucar.edu/wrf for details on the type of system required, data inputs, and other info you will need to get off run the model.

Hi everyone, I am brand new to this list. If my questions have already been answered, please inform me of where I can find a message list archive. (I am very new to GEMPAK) How do I make NIDS files available for viewing within NMAP. I have the following information: The filenames appear as: maple_cmp_fcst_200708082145_200708082215.mos The NIDS files are on a 2km grid in a Lambert Conformal projection, with a grid size of 2560 by 1792. The centre lat/lon is 39/-98. Output reference lat1 is 33 and output reference lat2 is 45. The NIDS product code is 140. Secondly, I have a gridded mosaic of Canadian radar data which I would like to translate via the 700hPa GEM regional model wind field. My goal is to create a very short term nowcast. Are there any tools within GEMPAK which would allow me to do this or has anyone else attempted to perform a similar task?
