          Termination of NWS Ozone Air Quality Predictions

ozone air quality predictions and developmental predictions of
fine particulate matter (PM2.5) produced using the Community
Model for Air Quality (CMAQ) at the National Centers for
Environmental Prediction (NCEP). This termination is proposed
due to the current fiscal environment. NWS will maintain
operational air quality predictions of smoke, dust, and volcanic
ash, as well as dispersion model predictions for the emergency
management community responding to harmful releases.

26, 2012, to:

nwssp.comments@xxxxxxxx

NWS will evaluate all comments to determine whether to proceed
with this termination. It is expected that the operational ozone
output will be terminated on or about March 5, 2013, and the
experimental ozone output and developmental PM2.5 predictions
will be terminated on or about January 22, 2013.

Specifically, this will result in the termination of all surface
ozone and developmental PM2.5 predictions over the CONUS, Alaska
and Hawaii that are made from the 06 UTC and 12 UTC prediction
cycles.

All web-based ozone prediction displays at:

http://airquality.weather.gov/

will no longer be available, including the following graphical
displays and numerical tables for operational ozone predictions
over the CONUS, Alaska and Hawaii:

- The 1 hour average ozone concentration at the lowest model
layer near the surface

- The 8 hour average ozone concentration at the lowest model
layer near the surface

- The 1 hour average daily maximum ozone concentration at
the lowest model layer near the surface

- The 8 hour average daily maximum ozone concentration at
the lowest model layer near the surface.


Operational ozone predictions from the NWS National Digital
Guidance Database (NDGD) server at:

will no longer be available, including the following files for
the CONUS, Alaska and Hawaii:

the lowest model layer near the surface.

the lowest model layer near the surface.

- ds.mozone01.bin: The 1 hour average daily maximum ozone
concentration at the lowest model layer near the surface.

- ds.mozone08.bin: The 8 hour average daily maximum ozone
concentration at the lowest model layer near the surface.

Operational ozone predictions will no longer be available from
the NCEP server:

and from the Real-Time NOMADS server:

In addition, the experimental CMAQ system that provides
developmental Fine Particulate Matter (PM2.5) predictions for
the CONUS will be terminated.  The experimental CMAQ is executed
for the 06 UTC and 12 UTC cycles at NCEP.  The developmental
PM2.5 predictions are normally only available to the NWS Air
Quality Forecaster Focus Group.
