| D Region Absorption Prediction, Release 2 |
The D-Region Absorption Prediction, Release 2
(D-RAP2) product provides a suite of graphic and
text information about the global High Frequency
(HF) radio propagation conditions related to the
state of the ionosphere’s D-region. D-RAP2 will
be web based
(http://www.swpc.noaa.gov/drap/index.html) and is
an enhancement of the current D Region Absorption
Prediction product
(http://www.swpc.noaa.gov/dregion/index.html).
D-RAP2 fills a void that exists in the current
product by providing absorption information due
to energetic proton precipitation at high
latitudes. The web site provides:
o A main page containing a global map of the
highest HF frequencies affected by a 1dB
attenuation, estimated recovery times, and links
to subordinate pages.

| Western Region Standardized Fire Weather Web Pages |
The need for improved fire weather information
via the internet by land
management and fire suppression agencies in
Western Region (WR) is continually increasing.
Multiple fire weather user agencies have
requested a consistent WFO fire weather web page
layout and more interactive graphical web pages
to provide critical fire weather information.
To account for these requests, WR tested
consistent, interactive, fire weather web pages
at every WR WFO from August 1, 2008 to June 1,
2009. Customer comment via a standard web
survey,e-mail and face-to-face fire weather
meetings was overwhelmingly positive. The pages
became operational on November 2, 2009. |

| Hazard Grids in the National Digital Forecast Database |
The NWS provides access to operational and
experimental gridded forecasts of weather
elements (e.g., maximum temperature, sky
cover)through the NDFD. The NDFD contains a
seamless mosaic of digital forecasts from NWS
field offices working in collaboration with the
National Centers for Environmental Prediction
(NCEP). The hazard grids are prepared by all
Weather Forecast Offices (WFO) and are available
via the NDFD. Hazard grids are valid for more
than two hours. The hazard grids depict all
active long duration watch, warning and advisory
hazards issued by NWS WFOs . The hazard grids
include long duration coastal, marine,
nonprecipitation, tropical and winter weather
hazards. It also includes convective and some
hydrological watches. It does not include the
following short duration warnings: Tornado
Warning, Severe Thunderstorm Warning, Extreme
Wind Warning, Flash Flood Warning, and Special
Marine Warning. It does not include the following
Long Duration Watches and Warnings issued in
RiverPro and WarnGen:Flood Watch for forecast
points, Areal Flood Warnings and Flood Warnings
for forecast points. In addition, it initially
will not include Gale Warnings, Storm Warnings
and Hurricane Force Wind Warnings issued in the
Offshore and High Seas forecast by OPC and TAFB.
The NDFD Hazard grid definition is defined as,a
weather or hydrologic hazardous event issued for
the protection of life and property and the
enhancement of the national economy.
The Hazards grid will be in experimental status
in the NWS Alaska Region until further notice. |

| National Digital Forecast Database User Defined GRIB2 files |
Gridded forecasts requested by a user from the
National Digital Forecast Database (NDFD) are
encoded into GRIB2 and transmitted to that user
via the World Wide Web (WWW). A user can be any
member of the public, a government agency, or a
commercial enterprise. The user chooses one of
the weather elements that is available in the
NDFD and specifies the bounding latitudes and
longitudes of the grid that will be transmitted
via a Web CGI interface. GRIB2 is data encoding
standard described by the World Meteorological
Organization in its document FM92 GRIB, Edition
2, Code Form and Tables.... |

| NWS web services via wireless technologies |
NWS is responsible to make its weather, water and
climate information widely availableto taxpayers
using commonly accepted standards and
technologies. One of the most widely accepted,
available and cost effective means of
accomplishing this objective is
the use of web services via the internet, and NWS
has implemented a corporate-wide HTTP-based web
service. This service has allowed users instant
access to current NWS information via industry
standard web browsers and internet connections. A
rapidly evolving technology in the United States
today is the ability to access internet content
via wireless devices such as Personal Digital
Assistants (PDA) and cell phones.

| Fire Weather Point Forecast Matrix |
Land management agencies in Georgia and North
Carolina have expressed a need for easily
accessible tabular forecast data that is tailored
toward fire behavior applications. A fire weather
version of the Point Forecast Matrix (PFM) table
fits this need well because it allows agency
specialists to quickly run simple fire behavior
models for planning purposes. The product is
called the Fire Weather Point Forecast Matrix
(PFW) and is generated routinely for the National
Fire Danger Rating System (NFDRS) sites or other
areas as determined by the users. This additional
data will help land management agencies to ensure
the safety of fire crews as well as better plan
prescribed burns and other projects in a cost and
resource effective manner. Also, land managers
have expressed a need for better tools to predict
and manage smoke dispersion. They have also
requested that the NWS include an Atmospheric
Dispersion Index (ADI) and Low Visibility
Occurrence Risk Index (LVORI) in the PFW product.
WFO Fire Weather PFW’s are generated for the
Remote Automated Weather Station (RAWS)/NFDRS
sites using an edited version of the standard PFM
formatter. This formatter produces needed fire
weather parameters from the local WFO’s Digital
Forecast Database (DFD). PFW's can be generated
for any grid point in a DFD based upon user
request. The web delivery of the product for
fire weather customers will include a disclaimer
at the top of the page stating “This product is
for planning and review purposes only and is not
to be substituted for an official fire weather
spot forecast. The data displayed are calculated
from a 5.0 by 5.0 km digital database and only
approximates weather conditions in highly varying
terrain. Please relay any comments you have to
your local NWS office.
An example of the PFW can be seen at:

| Observed Precipitation Map |
The National Weather Service (NWS) collects
rainfall data to support its forecast and warning
operations. Individual River Forecast Centers
(RFCs)and Weather Forecast Offices typically
provide rainfall collectives in text format and
graphical format for their areas of
responsibility. The National Centers for
Environmental Prediction (NCEP) Climate
Prediction Center (CPC), collects additional data
from cooperative observers. This rainfall data is
made available to HPC and is used extensively for
verification purposes.This rainfall data is
plotted on a map of the CONUS and made available
to
forecasters. The data is used for feedback on
forecast accuracy and can be used in case
studies and other scientific endeavors. |
