<p><font face="Arial">Can someone please explain to me how the bracketed notation works to extract data from a GDS. By this I mean the following:</font></p>
<p><font face="Arial"></font> </p>
<p><a href="http://metserver:9090/dods/neww3/neww3.00z.ascii?htsgwsfc[0:20][0:40][110][72" target="_blank"><font color="#000000"><em><font face="Arial">http://metserver:9090/dods/neww3/neww3.00z.ascii?htsgwsfc[0:20][0:40][110][72</font></a><font face="Arial">]</font></em><font face="Arial">
</font></font></p>
<p><em><font face="Arial"></font></em> </p>
<p><font face="Arial">which extracts htsgwsfc over ensemble members 1-21 (0-20 when zero based), time values 0-40 at x=110 and y=72 and gives an ascii text file I can grab using something like wget.</font></p>
<p><font face="Arial"></font> </p>
<p><font face="Arial">Am I able to use this kind of notation in GrADS scripts to access a chunk of data that I can define to a variable?</font></p>
<p><font face="Arial"></font> </p>
<p><font face="Arial">e.g.</font></p>
<p><font face="Arial"></font> </p>
<p><font face="Arial">'define myvar = </font><a href="http://metserver:9090/dods/neww3/neww3.00z.ascii?htsgwsfc[0:20][0:40][110][72" target="_blank"><font color="#000000" face="Arial"><em></a><a href="http://metserver:9090/dods/neww3/neww3.00z.?htsgwsfc[0:20][0:40][110][72]'" target="_blank">http://metserver:9090/dods/neww3/neww3.00z<u>.?htsgwsfc[0:20][0:40][110][72</a></u>]'</em></font></p>
<p><font face="Arial"></font> </p>
<p><font face="Arial">All combinations I try don't work and I can't find any documentation on it.</font></p>
<p><font face="Arial"></font> </p>
<p><font face="Arial">I have looked at the documentation for access using the curly bracket notation, e.g.:</font></p>
<p><a href="http://metserver:9090/dods/_expr_{neww3/neww3.t00z}{htsgwsfc}{73:73,111:111,1:1,00Z20MAY2014:00Z25MAY2014}" target="_blank"><font color="#000000" face="Arial"><em>http://metserver:9090/dods/_expr_{neww3/neww3.t00z}{htsgwsfc}{73:73,111:111,1:1,00Z20MAY2014:00Z25MAY2014}</em></font></a></p>
<p><font face="Arial"></font> </p>
<p><font face="Arial">...but I don't seem to be able to capture the ensemble dimension using this format.</font></p>
<p><font face="Arial"></font> </p>
<p><font face="Arial">Any help will be greatly appreciated.</font></p>
