<div>Hi Mickias,</div>
<div> </div>
<div>Why don't you try just to remove<strong> h </strong>(history) in the Registry for the output variables (especially 4D)</div>
<div>you don't need in your output stream. I used to run 30-50 years for wind purposes (wind farms)</div>
<div>and usually left U,V, T, P and T in main output.</div>
<div>Please don't forget to recompile WRF after editing Registry file.</div>
<div> </div>
<div>Good luck,</div>
<div>Dr Mikhail Titov</div>

<div class="gmail_default" style="font-family: "comic sans ms" , sans-serif;font-size: small;color: rgb(11,83,148);">Thank you very much for your email. Yes, I've used the model output from NCAR to enforce my model (NCAR CESM Global Bias-Corrected CMIP5 Output to Support WRF/MPAS Research) and I'm interested in simulating from 1970 to 2005 for the past and do the same in the mid-century. No need to do ungrib in this case as the data is already in intermediate format and I've downloaded the data for the entire time frame. My concern is, for that one-year successful simulation I did, the size of wrfbody is about 20 GB and I'm concerned how big it's going to be for the entire 30 years? I'm wondering if there is a way to break the 30 years simulation into fewer number of years such as three 10 years while I run the metgrid.exe and real.exe?</div>

<div style="font-family: trebuchet ms , sans-serif;">Hi Mickias,<br/>
</div>
<div style="font-family: trebuchet ms , sans-serif;">I assume that you had your initial and boundary conditions for meteorology for the one year that you ran the model for, in your wrfinput and wrfbdy files. You must have produced these files through ungrib and metgrid utilities, and must have downloaded a reanalysis or global model data like FNL/GFS or ECMWF to create these files.<br/>
</div>
<div style="font-family: trebuchet ms , sans-serif;">You cannot run a regional model (WRF) without initial and (more importantly) boundary conditions. So you'll have to first run a global model for the 30 years past and 30 years future, or alternatively contact someone who has run it and has the output available for that period. Then use that data (instead of FNL etc.) to create new wrfinput and wrfbdy files. This would require a fair amount of restructuring and reformatting of data if you want it to be processed by WPS. Once you've produced your wrfinput and wrfbdy files for the required period, you can go ahead and run WRF.<br/>
<br/>

<div style="font-family: trebuchet ms , sans-serif;">Good luck!<br/>

Can I just adjust the dates in my namelist.wps to my 30 years span timeframe and run geogrid and do the rest of the running processes as one continuous simulation?
