<p>Hi again,</p>
<p>For you wondering why are there two system and when to use which
here is some info:</p>
<p>The two systems are meant to provide complementary information.
Both are good for getting locations of plumes and clouds. They
both run out of GFS, but they have different configuration (e.g.,
horizontal resolution, cloud microphysics scheme, aerosol scheme,
feedbacks) and initialization (UIOWA initialized from latest GFS,
NCAR has 4 days of spinup with FNL with nudging above the cloud
layer) so smoke plumes and clouds could look different. Both
systems are also forced by AOD observations (NCAR uses and
inversion scheme, while UIOWA uses 3DVAR assimilation), so both
should be good for smoke concentrations and AOD loads.</p>
<p>The main differences are: <br>
</p>
<p>The WRF-Chem (UIOWA) has full-chemistry, so you can get detailed
aerosol speciation (OC, BC, SO4, etc) from it. It also has
forecasts of gases (O3, NOx, SO2, biogenics, etc.). <br>
</p>
The WRF with aerosol-aware microphysics (NCAR) is good for spotting
locations with aerosol-cloud-radiation interactions, as there are
two simulations running simultaneously with and without smoke
emissions and the differences between them are included in the
plots. Also, it has 15 tracers each tagged to one day of biomass
burning emissions, so it's good to getting an smoke age estimate.<br>
<br>
Let me know if you have other questions/comments<br>

<p>Hi all,</p>
<p>Hoping that everything will work out in Namibia, we have our
forecast systems up and running. As we discussed in our last
science meeting, we have two systems:</p>

<p>You can read the whole description in the webpage. One of the
highlights is that the "DIFF" fields gives you the differences
between simulations turning on and off fire emissions, so you
can see the effects of the aerosol-cloud-radiation interactions
in variables such as cloud number concentrations, cloud-top
height, LWP and temperature (see sample below). Also, I added
tracers to track biomass burning emitted on a range of 15 days
(some of them are still filling up, so you might see zeros). I
plan to compute age estimates based on these tracers.</p>
<p><b>2) U of IOWA forecasts: </b><br>

<p>These are full-chemistry WRF-Chem simulations including data
assimilation. This system is very similar to what we used in
KORUS-AQ (if you were there). Only aerosol-radiation
interactions are included in this configuration, interactions
will clouds will be included in post-campaign analysis.</p>

</p>
We are still working in some details like titles overlapping with
dates and the runs being updated. Let us know of any other issues
you find and any suggestions of additional variables we could plot<br>
<br>
thanks!<br>
