Hi All,<br>
We are trying to convert TMI SST binary data to GRIB1 format (WRF<br>
compatible) using lats4d. we tried to change the parameter table available in<br>
<a href="http://www-pcmdi.llnl.gov/software/lats/parmfile.html" target="_blank">http://www-pcmdi.llnl.gov/software/lats/parmfile.html</a><br>
but we could not succeed. Can any one help us in providing the<br>
parameter table that can be used to convert TMI to GRIB1 (WRF) format.<br>
We will be grateful to receive any help in this regard.<br>
</blockquote><div><br></div><div>My suggestion would be for you to first let lats4d produce a table automatically (the file name is ".grads.lats.table") and then rename this file and make the necessary changes to make it WRF compatible. There are comments in the automatically generated file. Most likely you will be editing the variable table, certainly the ID column and probably the UNITS column as well. I suspect you can use this NCEP's ops table to figure out the "ID" of each variable:</div>

<div><br></div><div>Once you have a candidate table, rerun lats4d providing this table.</div></div><div><br></div><div>Disclaimer: I've never prepared WRF files myself. If you are successful, could you please post the detailed procedure to gradsusr? </div>
