Subject: Comments
Requested by November 26, 2012, on Proposed
Termination of NWS Ozone Air Quality Predictions
NWS is proposing to terminate all operational
and experimental 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.
Please provide comments on the proposed
termination, by November 26, 2012, to:
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:
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndgd/GT.aq/
will no longer be available, including the following files for the CONUS,
Alaska and Hawaii:
- ds.ozone01.bin: The 1 hour average ozone
concentration at the lowest
model layer near the surface.
- ds.ozone08.bin: The 8 hour average ozone
concentration at 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:
ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/aqm/prod/
http://www.ftp.ncep.noaa.gov/data/nccf/com/aqm/prod/
and from the Real-Time NOMADS server:
http://nomads.ncep.noaa.gov/pub/data/nccf/com/aqm/prod/
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.
Experimental ozone prediction displays at:
http://airquality.weather.gov/expr
will no longer be available, including the following experimental
ozone displays for:
- 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.
Experimental ozone predictions from the NWS
National Digital Guidance Database (NDGD) server at:
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.aq/
will no longer be available, including the following experimental
ozone files for the CONUS:
- ds.ozone01.bin: The 1 hour average ozone
concentration at the lowest
model layer near the surface.
- ds.ozone08.bin: The 8 hour average ozone
concentration at the lowest
model layer near the surface.
- ds.pozone01.bin: The 1 hour average daily
maximum ozone concentration at the lowest model layer near
the surface.
- ds.pozone08.bin: The 8 hour average daily
maximum ozone concentration at the lowest model layer near
the surface.
Experimental ozone predictions will no longer
be available from the NCEP server:
ftp://ftp.ncep.noaa.gov/pub/data/nccf/com/aqm/para/
http://www.ftp.ncep.noaa.gov/data/nccf/com/aqm/para/
and from the Real-Time NOMADS server:
http://nomads.ncep.noaa.gov/pub/data/nccf/com/aqm/para/ .
Please note that NOAA’s ozone predictions
will no longer be available for automatic generation of air quality products
distributed through Websites and other means outside of NOAA, including, but
not limited to:
