<TITLE>Uses of external soil temperature and moisture in WRF</TITLE>

<P><FONT SIZE=2>Dear WRF Community:<BR>
<BR>
When WRF is run with a land surface model (e.g., NOAH), it requires soil<BR>
temperature and moisture values from the WPS. Question: does the<BR>
WRF *only* use these values for its initial condition, or does it also use<BR>
these values throughout the simulation? If the latter, how are these values<BR>
used? (Are they boundary conditions along the north, south, east,<BR>
and west sides of the grid? Are they boundary conditions for the<BR>
bottom layer? Are they used directly at the surface?)<BR>
<BR>
Thanks,<BR>
<BR>
