Sir</SPAN></FONT></DIV>
<DIV><FONT face="Humanst521 Lt BT"><SPAN class=044480500-07082009>I conducted
the two experiments with real data, the first is WRRv31_18 which runs WRF
day by day separately. The second one is WRFv31_19, running WRF continuously .
By comparing against observations, I found that the bias of WRFv31_19 is
much bigger than that of WRFv31_18 for temperature and wind speed. See the bias
bar for the two runs attached. I wonder if we have to run WRFv31 day by day
for "better" metrological data for driving air quality model such as CMAQ and
CAMx. However this is expensive way because the longer CPU and computing
time are needed. So what is the reliable period to run
WRFv31 continuously for real case? Thank you for your
supports.</SPAN></FONT></DIV>
