<div dir="ltr"><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">Hi Mickias,<br><br></div><div class="gmail_default" 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><br></div><div class="gmail_default" 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><br></div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">Good luck!<br><br></div><div class="gmail_default" style="font-family:trebuchet ms,sans-serif">Tabish<br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_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>

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?
