Li,

It's odd this error you have. All of the source URL's are from an instance of 
the TDS, and work, at least to a certain extent. For example the second 
dataset's DDS can be seen with no problem here:


http://data.nodc.noaa.gov/thredds/dodsC/testdata/ghrsst_ncml/fullAgg/aggregate__ghrsst_L4_GLOB_NCDC_AVHRR_AMSR_OI.ncml.dds

Adding the constraint expression produces the correct result:

http://data.nodc.noaa.gov/thredds/dodsC/testdata/ghrsst_ncml/fullAgg/aggregate__ghrsst_L4_GLOB_NCDC_AVHRR_AMSR_OI.ncml.dds?analysed_sst%5B0:1:1439%5D%5B360%5D%5B720%5D

But the ASCII data request fails:

http://data.nodc.noaa.gov/thredds/dodsC/testdata/ghrsst_ncml/fullAgg/aggregate__ghrsst_L4_GLOB_NCDC_AVHRR_AMSR_OI.ncml.ascii?analysed_sst%5B0:1:1439%5D%5B360%5D%5B720%5D

(My requests for this URL time out with no response.)

However the error you submitted:

is unrelated to the TDS in that the referenced dataset URL: 
http://data.nodc.noaa.gov/opendap/hyrax/ghrsst/L4/GLOB/NCDC/AVHRR_AMSR_OI/2003/348/20031214-NCDC-L4LRblend-GLOB-v01-fv01_0-AVHRR_AMSR_OI.nc.bz2

References a different dataset on an instance of a Hyrax server, not a TDS.

I'm thinking there may be some copy/paste confusion happening that's mudding 
the waters here...
