Hi Yolanda: > Hello, > > I write to you in order to ask for help for a problem I encounter when > performing an aggregation though time dimension in thredds (using values from > filenames). > > Apparently the aggregation performs well when accessing the aggregated > dataset though opendap and ncss but fails when trying to get a subsetted > netcdf with ncss. i made a test that seemed to work. can you send me the URL that does not work ? > > I have opened the dataset in toolsui and it seems to be ok in the viewer tag > but in the featurestype tag it seems strange that the shape of the created > grid takes twice the time dimension but cannot understand why.

HDF4 files are notoriously bad. can you send me a sample file or two?? also, you need to list the variables to be aggregated, like this <variableAgg name="kk"/> <variableAgg name="l3m_data"/> > > > > The opendap url for the dataset is > > dods://150.241.234.101:8080/thredds/dodsC/ExampleNcML/Agg2.nc through > http://150.241.234.101:8080/thredds/MODIS_L3.html > > > > > > and my xml catalog is: > > > > <?xml version="1.0" encoding="UTF-8"?> > > <catalog name=" Catalog" > xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0" > > xmlns:xlink="http://www.w3.org/1999/xlink"> > > > > <service name="allServices" serviceType="Compound" base=""> > > <service name="ncdods" serviceType="OPENDAP" base="/thredds/dodsC/"/> > > <service name="HTTPServer" serviceType="HTTPServer" > base="/thredds/fileServer/"/> > > <service name="wcs" serviceType="WCS" base="/thredds/wcs/"/> > > <service name="wms" serviceType="WMS" base="/thredds/wms/" /> > > <service name="ncss" serviceType="NetcdfSubset" base="/thredds/ncss/grid/" /> > > <service name="ncstream" serviceType="NetcdfStream" base="/thredds/ncstream/" > /> > > </service> > > > > <dataset name="Example NcML Agg2" ID="ExampleNcML-Agg2" > urlPath="ExampleNcML/Agg2.nc"> > > <serviceName>allServices</serviceName> > > <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"> > > <aggregation dimName="time" type="joinNew" timeUnitsChange="true"> > > <scan location="/data/HDF/" suffix=".L3m_MO_NSST_4" > dateFormatMark="A#yyyyDDD" subdirs="false"/> > > > > <variable name="lon" shape="fakeDim1" type="double"> > > <attribute name="units" value="degrees_east"/> > > <values start="-180" increment="0.04166666"/> > > </variable> > > > > <variable name="lat" shape="fakeDim0" type="double"> > > <attribute name="units" value="degrees_north"/> > > <values start="90" increment="-0.04166666"/> > > </variable> > > > > <variable name="l3m_data"> > > <attribute name="units" value="degrees_Celsius"/> > > <attribute name="scale_factor" value="0.000717185"/> > > <attribute name="add_offset" value="-2.0"/> > > <attribute name="missing_value" value="0.0"/> > > <attribute name="standard_name" value="SST_MONTHLY_AVERAGE"/> > > </variable> > > > > </aggregation> > > </netcdf> > > </dataset> > > </catalog> > > > > _______________________________________________________________________________________ > > <http://www.azti.es/> <http://www.azti.es/> > > Yolanda Sagarminaga > > AZTI - Tecnalia / Unidad de Investigación Marina > > Herrera kaia portualdea z/g > 20110 Pasaia (Gipuzkoa) > Tel: 943 004 800 - Fax: 943 004 801 > e-mail: address@hidden > > www.azti.es ; www.tecnalia.info > > > > P Salva un árbol...por favor, no imprimas este correo a menos que realmente > lo necesites > > _______________________________________________________________________________ > > **************** LEGE OHARRA **************** AVISO LEGAL **************** > DISCLAIMER **************** > > Mezu hau pertsonala eta isilpekoa da eta baimenik gabeko erabilera debekatua > dago legalki.
