Brad, <br>
<br>
Here's something to check:<br>
How many bytes are in your file <font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">/home/bradn/WINDVERIF/comparing.dat
which </span></font>contains one record with 360 x 181 elements? If
your data is 32-bit, then your file should have 360 x 181 x 4 bytes. If
it has "360 x 181 + 2) x 4 bytes, then you need to add "options
sequential" to the descriptor file to account for the extra control
words (one at the start and one at the end of the record.) If it's
neither of these, then maybe the problem is how the file was written.<br>

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">When I plot the data in
GrADS, the data is not plotted
correctly. It appears that the proper values are not being assigned to
the
proper latitude and longitudes. For reference, my binary file lists the
variable’s
values in a 360 x 181 array, such that longitude is increasing with
increasing
row number, and latitude is increasing with increasing column number.<o:p></o:p></span></font></p>
<p class="MsoNormal"><font face="Arial" size="2"><span

<p class="MsoNormal"><font face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;">I would be very
appreciative if someone could help me solve
this. I have tested the plot using a fixed longitude of 1 degree and
latitude
of -90 to 90, and it appears to work. However, when I add a second
longitude of
2 degrees, it appears GrADS isn’t plotting correctly.<o:p></o:p></span></font></p>
