Hi,We recently upgraded ncWMS to add new functionality and for that we are using the java netcdf-4.0.48.4 library. However, we are now having difficulty displaying "wind stress" variable from a certain dataset; the library thinks that it's a vertical axis with units of pressure. Previously, we didn't have this problem with netcdf-4.0.
Following is a brief ncdump of the dataset using ToolsUI (version 4.0.48.5.2) :
dimensions:
x = 1442;
y = 1021;
deptht = 1;
time_counter = UNLIMITED; // (1 currently)
variables:
float nav_lon(y=1021, x=1442);
:units = "degrees_east";
:valid_min = -180.0f; // float
:valid_max = 180.0f; // float
:long_name = "Longitude";
:nav_model = "Default grid";
:_CoordinateAxisType = "Lon";
float nav_lat(y=1021, x=1442);
:units = "degrees_north";
:valid_min = -77.010475f; // float
:valid_max = 89.94787f; // float
:long_name = "Latitude";
:nav_model = "Default grid";
:_CoordinateAxisType = "Lat";
float deptht(deptht=1);
:units = "m";
:positive = "unknown";
:valid_min = 0.0f; // float
:valid_max = 0.0f; // float
:title = "deptht";
:long_name = "Vertical T levels";
:_CoordinateAxisType = "Height";
:_CoordinateZisPositive = "unknown";
float time_counter(time_counter=1);
:calendar = "gregorian";
:title = "Time";
:long_name = "Time axis";
float iocestru(time_counter=1, y=1021, x=1442);
:units = "Pa";
:missing_value = 0.0f; // float
:valid_min = -50.0f; // float
:valid_max = 50.0f; // float
:long_name = "Wind stress u";
:short_name = "iocestru";
:online_operation = "N/A";
:axis = "TYX";
:interval_operation = 432000.0f; // float
:interval_write = 432000.0f; // float
:associate = "time_counter deptht nav_lat nav_lon";
:_CoordinateAxisType = "Pressure";
:Conventions = "GDT 1.3";
:file_name =
"/data/perseus/users/dab/WORK/Exp4/ORCA025/ORCA025-R07-S/2007/ORCA025-R07_y2007m03d01_icemod.nc";
:production = "OPA9.0 beta"; :TimeStamp = "2008-OCT-15 10:29:42 GMT+0100"; }If I change the units to something other than Pa, then the variable is correctly recognised as a variable. Any suggestion will be much appreciated.
Cheers, Adit
