Hi all,
I have set up a TDS (Version 4.1.20100520.1554 - 20100520.1554) and I am having
some problem requesting for data using the built-in OPeNDAP service.
I am trying to subset the dataset based on a spatial extent (bbox), and in the
opendap documentation, it is mentioned that this is possible if you specify a
constraint in your request.
(http://opendap.org/user/guide-html/guide_34.html#id6)
I am getting the following error when I try to make a simple query
http://apacsrv6/thredds/dodsC/bom/mslp.2009043000.nc.ascii?mslp&lat>15.0 :
Error {
code = 2;
message = "The variable `15' was not found in the dataset.";
};
My Dataset is as follows:
Dataset {
Float32 lat[lat = 480];
Float32 lon[lon = 600];
Int32 tm_step_size;
Int32 base_date;
Int32 base_time;
Int32 valid_date[time = 1];
Int32 valid_time[time = 1];
String seg_type[time = 1];
Float32 mslp[time = 1][lat = 480][lon = 600];
} bom/mslp.2009043000.nc;
---------------------------------------------
lat[480]
-55.0, -54.875, -54.75, -54.625, .......
lon[600]
95.0, 95.125, 95.25, 95.375, 95.5, ......
tm_step_size, 240
base_date, 20090430
base_time, 0
valid_date[1]
20090430
valid_time[1]
0
seg_type[1]
"FORC"
mslp[1][480][600]
[0][0], 983.6426, 983.6654, 983.6847, 983.7006, ....
[0][1], ....
.....
I have noted that the syntax of the OPeNDAP request within thredds is a bit
different, could someone kindly assist?
Thank you for your time.
