dear GrADS experts, <div><br></div><div>i successfully used the SDFWRITE command to write a regular grads-format data into a NETCDF file. thank you very much! it's really convenient in the latest version of GrADS!</div>
<div><br></div><div>i do have a question, however. is it possible to indicate a Special Time (e.g., Specific Date of the Beginning of the Data Sets) in the control files?</div><div><br></div><div>the data i'm looking is from the same model but split into different sets, due to the large size of the data. i hope to keep the information of the FIRST DAY OF THE MODEL OUTPUT in each of the netcdf file.</div>
<div><br></div><div>the control files i have are like this: </div><div><br></div><div>for first set of data:</div><div><br></div><div><div>dset ^Out1.dat</div><div>OPTIONS LITTLE_ENDIAN </div><div>undef -9999.</div><div>title FRCN 20C3M Run1 Specific Humidity </div>
<div>XDEF 100 LINEAR 0 0.25</div><div>YDEF 60 LINEAR 0 0.25</div><div>ZDEF 10 LEVELS 1000 925 850 750 700 600 500 400 300 200</div><div>-->TDEF 365 LINEAR 1jan1981 1dy</div><div>VARS 1</div><div>q 9 0 mm/day</div>
<div>endvars</div></div><div><br></div><div>for the 2nd set of data:</div><div><br></div><div><div><div>dset ^Out2.dat</div><div>OPTIONS LITTLE_ENDIAN </div><div>undef -9999.</div><div>title FRCN 20C3M Run1 Specific Humidity </div>
<div>XDEF 100 LINEAR 0 0.25</div><div>YDEF 60 LINEAR 0 0.25</div><div>ZDEF 10 LEVELS 1000 925 850 750 700 600 500 400 300 200</div><div>--> TDEF 365 LINEAR 1jan1982 1dy</div><div>VARS 1</div><div>q 9 0 mm/day</div>
<div>endvars</div></div></div><div><br></div><div>the "TDEF" indicate the starting time of each specific data set. Then I used sdfwrite function to convert these data sets into netcdf files. i hope to keep the information of the FIRST DATE OF THE MODEL OUTPUT in each netcdf file.</div>
<div><br></div><div>i googled this issue but didn't find the answer =( is there a way to add such an information?</div><div><br></div><div>thank you very much!</div><div><br></div><div>sincerely,</div><div>shing</div>
