This is very simple problem. U set x and y as points instead of lat, lon<br>
while using fwrite.<br>

Hai Rupak,<br>
<br>
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" target="_blank">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" target="_blank">uwnd09daily.nc</a> '<br>
'sdfwrite u'<br>
<br>
This will write the newly defined variable to an external file (here <a href="http://uwnd09daily.nc" target="_blank">uwnd09daily.nc</a> ) .<br>

Hi,<br>
<br>
<br>
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.<br>
<br>
<br>
Any help in this regard is appreciated.<br>
<br>
<br>
Thanking you,<br>
<br>
