Hai <font><font color="#888888"><span style="color: rgb(0, 0, 0);">Rupak,</span><br><br> <font color="#000000">This problem may happen due to the x and y axis you set for using fwrite. An easy way to avoid this type of confusion is to write the output in netcdf format using sdfwrite command ( above grads version 2.0). An example is <br>
<br>'reinit'<br>'sdfopen <a href="http://uwnd.2009.nc">uwnd.2009.nc</a>'<br>'set lon 0 360'<br>'set lat -90 90'<br>'set time 01jan2009 04nov2009'<br>'set lev 1000 10'<br>'define u=uwnd'<br>
'set sdfwrite <a href="http://uwnd09daily.nc">uwnd09daily.nc</a>'<br>'sdfwrite u'<br><br>This will write the newly defined variable to an external file (here </font></font></font><font><font color="#888888"><font color="#000000"><a href="http://uwnd09daily.nc">uwnd09daily.nc</a>)</font></font></font><font><font color="#888888"><font color="#000000">.<br>

Hi,<div><br></div><div>I am trying to convert TRMM 3B42.V6 3-hourly rainfall data files into single daily rainfall file using GrADS 'fwrite'. The script is working well. But when I compare the newly generated maps with the original, they are different. The scales for both the maps are same but the rainfall spots are different. I think, there is a mix-up in x,y direction. If this is the case, how do I resolve it. As an example, i am attaching a figure displaying comparison map and the script file with this mail.</div>
<div><br></div><div>Any help in this regard is appreciated.</div><div><br></div><div>Thanking you,</div><div><br></div><font color="#888888"><div>Rupak Rajbhandari</div><div>Department of Meteorology</div><div>Trichandra Campus, TC/TU</div>
