The surface variables are available at 3-hourly intervals, but you can just use the 6-hourly data (or interpolate the 6-hourly data to 3hrs in ungrib). Note that specific humidity is available at 6-hourly intervals, too (hus). This should be enough to run WRF, but it might require a few changes to the namelists (e.g., use_tavg_for_tsk to compensate for the missing 6-hourly skin temperature). This page might be helpful, too: <a href="http://www.meteo.unican.es/wiki/cordexwrf/SoftwareTools/CmorPreprocessor">http://www.meteo.unican.es/wiki/cordexwrf/SoftwareTools/CmorPreprocessor</a></div><div><br></div><div><div><b>3-hourly:</b></div><div>huss</div><div>tas</div><div>uas</div><div>vas</div><div><br></div><div><b>6-hourly (model level):</b></div><div>ps</div><div>hus</div><div>ta</div><div>ua</div><div>va</div><div><br></div><div><b>6-hourly (pressure level):</b></div><div>psl</div><div><br></div><div><b>monthly:</b></div><div>ts</div><div>mrlsl</div><div>tsl</div><div><br></div><div><b>static:</b></div><div>orog</div><div>sftlf</div></div><div><br></div><div>Cheers</div><div><br></div><div>Dom</div><div><br><div><div>On 12/07/2014, at 4:01 pm, Jose Augusto Paixão Veiga <<a href="mailto:veiga.uea@gmail.com">veiga.uea@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr"><div style="margin: 0px; font-size: 12px; font-family: Helvetica;">Dear all,</div><div style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></div><div style="margin: 0px; font-size: 12px; font-family: Helvetica;">someone could tell me please what is the minimal number of variables necessary to make a run with WRF? I am asking this because I need to use data from HadGEM-2-ES model to force WRF for a couple of experiments for present climate (1980-2000) and future climate (2080-2100, RCP8.5). </div><div style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></div><div style="margin: 0px; font-size: 12px; font-family: Helvetica;">In a first look at Vtable.GFS (that I usually use for my runs) I saw the data dependencies from Temperature (T), U, V, Relative Humidity (RH), Height, T at 2 m, RH at 2 m, U at 2 m, V at 2 m, Surface Pressure, Sea-Level-Pressure, Soil Moist for 4 layers, T bellow ground for 4 layers, Ice flag, Land/Sea flag, Skin Temperature, terrain field, water equivalent snow depth and physical snow depth. </div><div style="margin: 0px; font-size: 12px; font-family: Helvetica; min-height: 14px;"><br></div><div style="margin: 0px; font-size: 12px; font-family: Helvetica;">However, for ESGF portal where I intend download data from HadGEM-2-ES experiments the available variables, at 6/6h frequency, are just 6: T, U, V, Sea-Level-Pressure, Specific Humidity and Surface Air Pressure, i. e., there are no variables of RH, T at 2m, U and V at 2 meters, T skin (or SST) among others cited before. So, how can I run WRF? </div><p style="margin:0px;font-size:12px;font-family:Helvetica;min-height:14px"> <br class="webkit-block-placeholder"></p><div style="margin: 0px; font-size: 12px; font-family: Helvetica;">I really appreciate if some one could help me with this doubt.</div><div><div dir="ltr"><div><span style="font-family:arial,sans-serif;font-size:13px;border-collapse:collapse"><br>
