<br>
I'm trying to make a runtime modification to the variables which are written into the wrfrst* files<br>
(using a text file defined by the "iofields_filename" option in the namelist), however I cannot work<br>
out which data stream the wrfrst* files are written from. Could anyone advise me if this is possible<br>
to do or not, and if it is possible then how should I write my commands to do this?<br>
<br>
Thanks,<br>
Doug<br>
