<p>Dear Nikhil,</p>
<p><br>
</p>
<p>Thanks for your heartiest cooperation. Finally, I have downloaded pressure levels and surface data. I have seen some posts in WRF users group that they run <b style="font-size: 12pt; font-family: 'Times New Roman';">calc_ecmwf_p.exe </b><span style="font-size: 12pt;">between
ungrib.exe and metgrid.exe. </span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Could you tell me please is it always essential if I use ERA-interim data.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Also I have seen that if I want to run </span><b style="font-size: 12pt; font-family: 'Times New Roman';">calc_ecmwf_p.exe</b><span style="font-size: 12pt;">,then I need </span><span style="font-family: 'Times New Roman'; font-size: 12pt;"><b>ecmwf_coeffs</b> </span><span style="font-size: 12pt;">table
in the working directory. According to ARW </span><span style="font-size: 12pt;">user guide, I have found a</span><span style="font-size: 12pt;"> link "</span><a href="http://www.ecmwf.int/products/data/technical/model_levels/index.html" id="LPlnk848193" style="font-size: 12pt;" title="http://www.ecmwf.int/products/data/technical/model_levels/index.html
Ctrl+Click or tap to follow the link">http://www.ecmwf.int/products/data/technical/model_levels/index.html</a><span style="font-size: 12pt;">" </span><span style="font-size: 12pt;">for </span><span style="font-size: 12pt; font-family: 'Times New Roman';">ecmwf_coeffs</span><span style="font-size: 12pt; font-family: 'Times New Roman';"> </span><span style="font-size: 12pt;">table.
But the table is not existed in that link. I want to </span><span style="font-size: 12pt;">use "e_vert=50 or 60". </span></p>
<p><span style="font-size: 12pt;">Could you please suggest any link or any sample where I can get </span><b style="font-size: 12pt; font-family: 'Times New Roman';">ecmwf_coeffs</b><span style="font-size: 12pt; font-family: 'Times New Roman';"> </span><span style="font-size: 12pt;">table. </span></p>
<p><span style="font-size: 12pt;">Could you please advise what criteria I have to follow to edit that table.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Your further suggestions will be highly appreciated.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Kind regards,</span></p>

First I have tried to use FNL data for WRF model. But I am not getting the good results compared to observation data. Therefore, I wish to use ERA-interim data. I have seen on the following website that there are different types (Types of Level) data sets such
as <b>Model Levels, Pressure Levels, Surface Levels</b> and so on.</p>

(1) Could you tell me please what is the criteria to select different data options. Do I need all types of data into same folder? Or I can use any of them.</p>

(2) Do I need any preprocessing work after downloading the data and before use in WRF model? Is it need to change anything in Vtable?</p>

18 hrs. If so, then how I can do that.</span></p>
