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:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)"><br></div><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)">Thank you very much again and any help would be highly appreciated.</div><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)"><br></div><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)">Kind regards,</div><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)"><br></div><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)">Mickias,</div><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)"><br></div><div style="font-family:"comic sans ms",sans-serif;font-size:small;color:rgb(11,83,148)"><br></div><div class="gmail_extra"><div><div class="h5"><br><div class="gmail_quote">On Thu, Feb 23, 2017 at 9:35 AM, Tabish Ansari <span dir="ltr"><<a href="mailto:tabishumaransari@gmail.com" target="_blank">tabishumaransari@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div style="font-family:trebuchet ms,sans-serif">Hi Mickias,<br><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.

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><br></div><div style="font-family:trebuchet ms,sans-serif">Good luck!<br><br></div><div style="font-family:trebuchet ms,sans-serif">Tabish<br></div></div><div class="gmail_extra"><br clear="all"><div><div class="m_-6244322266035412753m_-1394742838965651244gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div><font size="1"><span style="font-family:tahoma,sans-serif">Tabish U Ansari<br></span></font></div><font size="1"><span style="font-family:tahoma,sans-serif">PhD student, Lancaster Environment Center<br></span></font></div><font size="1"><span style="font-family:tahoma,sans-serif">Lancaster Univeristy<br> <span>Bailrigg</span>, <span>Lancaster</span>, <br><span>LA1 4YW</span>, <span>United Kingdom</span></span></font><br></div></div></div>
