Re: [thredds] THREDDS & WCS

this one seems to be working:

 http://oceanwatch.pfeg.noaa.gov:8081/thredds/dodsC/satellite/AG/ssta/3day

but this one fails:

 http://oceanwatch.pfeg.noaa.gov:8081/thredds/dodsC/satellite/PH/ssta/1day

the reason is that the second one is not recognizing the vertical coordinate (needed for 
making a grid) (try putting each of those URLs into the "CoordSys" Tab on 
ToolsUI if you want to see how I noticed this).

works:

double altitude(altitude=1);
    :actual_range = 0.0, 0.0; // double
    :fraction_digits = 0; // int
    :long_name = "Altitude";
    :standard_name = "altitude";
    :units = "m";
    :axis = "Z";
    :_CoordinateAxisType = "Height";
    :_CoordinateZisPositive = "up";

doesnt work:

 float altitude(altitude=1);
    :actual_range = 0.0f, 0.0f; // float
    :fraction_digits = 0; // int
    :long_name = "Altitude";
    :standard_name = "altitude";
    :units = "m";
    :axis = "Z";

in fact both should work due to the axis attribute (I think), but we arent 
correctly handling it in CF. If you can add either or both coordinates, it 
should fix the problem for now:

    :_CoordinateAxisType = "Height";
    :_CoordinateZisPositive = "up";

let me know....
