The problem (I think) is that your current time dimensions settings do not overlap with the times available in your file #2.<br>
<br>
Your second file has 12 times but the line in the error message<br>
<div class="im">"Grid limits of request: X = 35 111 Y = 40 88 Z = 1 1 T = -119987 -119987 E = 1 1"<br>
</div>indicates that the time you have selected from the SST file is before the start of the surface current data (t=-119987).<br>
<br>
You can override the current time dimension settings (i.e. choose a particular time) by using, e.g.<br>
d u.2(t=1);v.2(t=1)<br>
to plot the first time of surface current data. You can choose any of the 12 times available in this way.<br>

Hai,<br>
<br>
I want to plot surface current above sst. For this I am using Argo sst data and<br>
Oscar surface current data. The details of this files are given below:<br>
----------------------------------------------------------------------------------------<br>
ga-> q file 1<br>
File 1 : 1x1 Monthly gridded climatology on Standard Levels<br>
Descriptor: Gr_clm_temp_lev_0_2000m.nc<br>
Binary: Gr_clm_temp_lev_0_2000m.nc<br>
Type = Gridded<br>
Xsize = 360 Ysize = 180 Zsize = 27 Tsize = 12 Esize = 1<br>
Number of Variables = 1<br>
temp 27 t,z,y,x argo temperature (degc)<br>
ga-> q file 2<br>
File 2 : OSCAR Surface current data climatology 2003-2010 averaged<br>
Descriptor: oscar2003_2010clim.ctl<br>
Binary: oscar2003_2010clim.bin<br>
Type = Gridded<br>
Xsize = 360 Ysize = 120 Zsize = 1 Tsize = 12 Esize = 1<br>
Number of Variables = 2<br>
u 1 99 zonal velocity component<br>
v 1 99 meridional velocity component<br>
-------------------------------------------------------------------------------------------<br>
<br>
I plotted the sst , but when I am trying to plot the surface current above sst, I am getting<br>
the following warning message.<br>
--------------------------------------------------------------------------------------------<br>

Please tell me how to solve this.<br>
