</DIV></FONT>
<DIV> </DIV>
<DIV>
<DIV>Hai,</DIV>
<DIV></DIV>
<DIV>I have taken a netcdf data file from the following link:</DIV>
<DIV>http://www.nio.org/index/option/com_nomenu/task/show/tid/2/sid/18/id/229</DIV>
<DIV></DIV>
<DIV>While I try to open this file in GrADS I got the following error message:</DIV>
<DIV>====================================================</DIV>
<DIV>ga-> sdfopen nioa_climatology_monthly_temp_salt_nio.nc</DIV>
<DIV>Scanning self-describing file: nioa_climatology_monthly_temp_salt_nio.nc</DIV>
<DIV>SDF Error: 365 day calendars are no longer supported by sdfopen.</DIV>
<DIV> To open this file with GrADS, use a descriptor file with</DIV>
<DIV> a complete TDEF entry and OPTIONS 365_day_calendar.</DIV>
<DIV>====================================================</DIV>
<DIV></DIV>
<DIV>Then I made a descriptor file as given below:</DIV>
<DIV>-----------------------------------------------------------------</DIV>
<DIV>DSET ^nioa_climatology_monthly_temp_salt_nio.nc</DIV>
<DIV>UNDEF -1.e+34f</DIV>
<DIV>XDEF 90 LINEAR 30.5 1</DIV>
<DIV>YDEF 70 LINEAR -29.5 1</DIV>
<DIV>ZDEF 24 LEVELS 0 10 20 30 50 75 100 125 150 200 250 300 400 500 600</DIV>
<DIV>700 800 900 1000 1100 1200 1300 1400 1500</DIV>
<DIV>TDEF 12 LINEAR 1Jan9999 1mo</DIV>
<DIV>OPTIONS 365_day_calendar</DIV>
<DIV>VARS 2</DIV>
<DIV>temp 24 0 NIOA climatology monthly temp (degC) NIO</DIV>
<DIV>salt 24 0 NIOA climatology monthly salt (psu) NIO</DIV>
<DIV>ENDVARS</DIV>
<DIV>--------------------------------------------------------------</DIV>
<DIV></DIV>
<DIV>Then I tried to open it using "xdfopen" command, but then I got the</DIV>
<DIV>following message:</DIV>
<DIV>======================================================</DIV>
<DIV>ga-> xdfopen nioa_climatology_monthly_temp_salt_nio.ctl</DIV>
<DIV>Scanning Descriptor File: nioa_climatology_monthly_temp_salt_nio.ctl</DIV>
<DIV>gadxdf error: Missing or invalid dimension size.</DIV>
<DIV> --> The invalid description file record is:</DIV>
<DIV> --> xdef 90 linear 30.5 1</DIV>
<DIV> The data file was not opened.</DIV>
<DIV>======================================================</DIV>
<DIV></DIV>
<DIV>Please give me your valuable suggestion to solve this problem.</DIV>
<DIV></DIV>
<DIV>The complete details of the data file is given below:</DIV>
