The Health of
the Networks (HoN) provides a set of performance measures used for monitoring
the various NOAA observing� networks
including the Cooperative Data Network (COOP). Performance measures for COOP
include data completeness, quality, and validity as well as period of record,
missing stations, and receipt timeliness on a monthly basis. A station
watchlist is also created identifying tempreature data changepoints over� a minimum of ten years. Reports are
distributed via email to the National Weather Service (NWS) regional offices
and are then forwarded to the appropriate Weather Forecast Office (WFO). In
addition to links to the �reports, the
HoN website also provides access to the dynamic graphing and mapping
applications. Tools are also provided for generating suspect station lists
based upon user-defined temperature and precipitation data value changes as a
result of the TempVal and PrecipVal processes.

This page
contains links to various station information options as well as report descriptions,
QC flag defintions, related publications, and additional websites.
The Cooperative Network options page is located at:

This page
provides access to the various types of reporting, graphing, and mapping
applications that are offered by station, state, WFO, NWS region, and RCC
region.
Report Distribution
HoN reports
are distributed in three releases � TD3201 data as Release 1, TD3202 data as
Release 2, and TD3200 as the Final Release.
Release 1 data
comes from the TD3201 archive and is comprised of
Release 2 data
comes from the TD3202 archive and has been quality controlled for internal
consistency checks. Quality Assurance and Data Completeness reports are
available approximately 60 days after the data month.
Final Release
data comes from the TD3200 archive and includes spatial QC and interactive
areial edits and serves as the primary COOP data archive at NCDC. All six
reports are available approximately 110 days after the data month.
Report
notifications are sent via email and include the appropriate links to the
reports. All reports are also available from the website. Currently, email
notification is limited to NWS regional representatives and a limited number of
NWS headquarters personnel. The reports are then forwarded to appropriate WFOs
if it is determined that further investigation is necessary.

Report Descriptions
Six types of
reports are generated from the HoN system � Data Completeness, Quality
Assurance, Data Validity, Missing Stations, Station Changepoint List, and the
Station Watchlist.�
Data
Completeness � Completeness
percentages are displayed for temperature and precipitation elements. Links are
included to the Monthly Data Listing, MI3, the Monthly Snapshot, and Station
Graphs. Completeness reports are available by state, NWS region, and RCC region
for Release 2 and Final Release data.
Quality
Assurance � This report
displays the number of identified errors, timeshifts, and missing values for
temperature and precipitation elements. Links are included to the Monthly Data
Listing, MI3, the Monthly Snapshot, and Station Graphs. Quality Assurance
reports are available by NWS region for Release 1and Release 2 data and by state,
NWS region, and RCC region for Final Release data.
Data Validity � Data Validity provideds a combination
of completeness percentages and quality for temperature and precipitation
elements. Links are included to the Monthly Data Listing, MI3, the Monthly
Snapshot, and Station Graphs. Validity reports are available by state, NWS
region, and RCC region for Final Release data only.
Missing
Stations � Missing
station lists are generated for each data month and display the begin date for
the station as well as the last data month received. Links are included to MI3,
Station Graphs, and Station Inventories. Missing reports are available by
state, NWS region, and RCC region for Release 2 and Final Release data.
Station Watchlist � The
station watchlist displays stations with a detected changepoint within the past
12 months that do not have a corresponding metadata change within 6 months of
the changepoint.� Links are included to
the Monthly Data Listing, MI3, the Watch Report, and Station Graphs. Watchlists
are available by NWS region for Final Release data only.
Station
Changepoint List �
Detected changepoints are displayed for max and min temperature elements. Links
are included to the Monthly Data Listing, MI3, the Watch Report, and Station
Graphs. Changepoint reports are available by NWS region for Final Release data
only.
Graphing Options
Graphs are available by station, WFO, state, NWS region, and RCC region. The begin and end dates default to the earliest and latest data available and can be changed by the user.
- Station options include completeness and quality, validity, metadata changes, receipt timeliness, and changepoint detection various elements/qualifiers.
- WFO, state, NWS region, and RCC region options include completeness and quality, validity, practice and equipment changes, receipt timeliness, station moves, stations reporting, and period of record for various elements/qualifiers.
Mapping Options
Maps are available by WFO and state for active stations as well as temperature and precipitation completeness, quality, and validity and �missing stations, station practice changes, receipt timeliness, period of record, open/closed/moved, and changepoint/watchlist.
The station options page also includes a station locator map.
Suspect Data Options
Suspect station lists are generated by WFO and user-defined parameters for the difference in observed versus �corrected� values for temperature and precipitation and are available for Final Release data only.
The detailed station data
listing includes links to the entire data month listing, the QA flags, and
Datzilla.
