1 Overview
This document depicts the product flows between NOAA source systems and FAA as well as
other sink systems in the NextGen 4-D Weather Data Cube IOC timeframe. The source systems
are providers of the products referenced in the IOC Product Flow Sheet which was drafted by
NOAA and FAA. The sink systems are receiving parties of the products provided by source
systems. This document is closely coupled with Attachment D, Data Dictionary, which provides
more details about the required products by NOAA and FAA sink systems.
2 Notation
The key words “SHALL”, “SHALL NOT”, “REQUIRED”, “MUST”, “MUST NOT”,
“SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY” and “OPTIONAL” in this
document are to be interpreted as described in IETF RFC 2119 [IETF 2119].
3 Purpose and Scope
This document is based on the IOC Product Flow Sheet version 11.5, which is an excel
spreadsheet developed by NOAA NWS SEC Analysis Branch and FAA. It has been verified by
Aviation Weather Services Branch and managed by the JPDO. The IOC Product Flow Sheet
contains target datasets required by FAA and NOAA systems along with their descriptive
technical information.
The information in this document represents a snapshot of the NOAA system-level architecture
as of March 2011. The Contractor is expected to follow up with each NOAA source system
provider by verifying up-to-date system configurations and understanding its evolving
architecture. For example, some NOAA source systems are expected to undergo infrastructure
enhancements that will introduce new datasets with different spatial and temporal resolutions.
The term „Cube Interface‟ refers to the hardware, software, and communication link to a Cube-
enabled provider or consumer system. Refer to the Statement of Work (SOW) for definition of
the Cube boundary. For the provider system, the Cube Interface is representative of the Data
Provider Interface (DPI) and Legacy Provider Interface (LPI). Whereas, the Cube Interface for a
consumer system is representative of the Data Consumer Interface (DCI). See Attachment E,
Interface Design Document, for more details on DPI, LPI, DCI, and the IP-based Private
Network depicted in diagrams throughout the remainder of this document.
4 Current Architecture
The diagram below illustrates the current system-level architecture between the NOAA and FAA
systems that participated in the FY10 Capability Evaluation (CE). This is a high-level diagram
for informational purposes only. The intent of this diagram is to show the complexity of current
system connectivity.

5 NOAA Source Systems (Source Data Sets)
The following organizations/systems have been identified as the major and most likely providers
of products/datasets listed in the IOC Product Flow Sheet v11.5. For each provider system, a
RECOMMENDED configuration is depicted.
5.1 Telecommunications Operations Center
The NWS Telecommunications Operations Center (TOC) is a critical component in the
collection and dissemination of weather data both domestically and internationally and will play
a key role in support of the 4-D Weather Data Cube. In the IOC timeframe, the TOC MAY
provide the following product groups:
Next Generation Radar (NEXRAD) level 3 products
National Digital Forecast Database products
Caribbean Weather Radar
HIPS Polar Orbiting Satellite Data (Alaska) (see HIPS Configuration #1)
Textual Products
NEXRAD products originate from 155 NEXRAD radars that are distributed across the CONUS.
These radars operate using different volume coverage patterns and in turn have varying
frequencies to scan their respective volume. Raw radar data is processed into level 2 and 3
products at each radar‟s adjacent Weather Forecast Office (WFO), or special center in some
cases. Both Level 2 and 3 products utilize OpsNet (formerly known as NOAAnet) as its
transport mechanism. The Level 2 products are passed from each of the WFOs (122) to the ROC
or TOC, depending on their geographical location. From there, Level 2 products can be accessed
using LDM from organizations that have Internet2 access. All Level 3 products are sent from
each WFO to the AWIPS National Control Facility (NCF) located at the TOC where they are
disseminated back to any AWIPS station via OpsNet as well as NOAAPort. Level 3 products
are also accessible from the NWSTG.
Note: The following configurations exclude NOAAPort/SBN to simplify diagrams.
5.1.1 NEXRAD Recommended Configuration
This configuration utilizes the current infrastructure to disseminate NEXRAD level 3 products to
the TOC/AWIPS NCF. Since the NCF serves as a hub for all the WFO‟s providing NEXRAD
level 3 products, it makes a good candidate entry point for the FAA to obtain these radar
products in a centralized manner.

The NDFD and NDGD can be considered a single point to access data (unlike the NEXRAD
level 3 products). In this case, the Cube Interface will serve all the NEXRAD level 3 products as
well as all the NDFD and NDGD products.

Currently, the TOC receives Caribbean Weather Radar via the International Satellite
Communications System (ISCS) and places it in the NWSTG (for more information on ISCS,
see Reference section below). The data consists of one product:
Caribbean Weather Radar
o Caribbean Radar Mosaic.
Since only one product is desired, it‟s feasible to utilize the current infrastructure to deliver the
product to the TOC, and serve it through TOC‟s Cube Interface. The following configuration
MAY be used to serve the Caribbean Radar Mosaic.

5.1.4 HIPS Polar Orbiting Satellite Recommended Configuration
There are two potential sources for HIPS, or HIPS-like, data. Both options are outlined below.
The Contractor shall coordinate with the Government to determine which source is most
appropriate for the future of NOAA.
The HIPS system is connected to NWS Alaska Region, and the system has been duplicated and
is made available from NWS Pacific Region as well. Once the data has been transferred to the
regions, it is then made available to their AWIPS stations via LDM. Currently the Alaska and
Pacific Region AWIPS are not configured to transfer HIPS products back to the AWIPS NCF at
the TOC. If this is chosen as the appropriate source, the OpsNet connection at one, or both, of
the regions need to be upgraded to handle the additional bandwidth required to transfer HIPS
products to AWIPS NCF where they can be made available via the Cube Interface located at the
TOC. The diagram below depicts the corresponding data flow.

The second option involves using the POES data covering Alaska as a replacement for HIPS
products. Currently, NOAA is turning more towards POES to be the satellite downlink for
Alaska, as opposed to HIPS. If POES data is decided as an equivalent source, then these datasets
can be made available at the proposed NSOF Cube Interface which would already ingest POES
data. The figure below depicts this configuration.

These textual products fall under the World Meteorological Organization (WMO), and come in
WMO ASCII formatted text, as well as other formats including: GRIB, GRID, BUFR, Redbook
graphics, and Vector Graphics. However, the FAA has only identified products falling under the
WMO ASCII text format.
Currently, these products are generated from many disparate sources, but are centrally collected
and disseminated from the TOC/NWSTG. Sources include, but are not limited to:
WFOs
NCEP subcenters
Mobil-land stations (ie. Storm Chasers)
Fixed-land stations

Cube, and in the future WIS will be a Cube consumer. For more information on WIS, refer to
http://www.wmo.int/pages/prog/www/WIS/ref_docs_en.html.
5.2 Meteorological Assimilation Data Ingest System
MADIS provides ingestion, integration, automated quality control (QC), and distribution support
for both NOAA and non-NOAA observations. In the IOC timeframe, MADIS MAY provide the
following product group:
Surface Observations
MADIS currently provides access to data through the internet via multiple protocols (FTP, LDM,
etc). In addition, MADIS data is also pushed and made available at the NWSTG. In the IOC
timeframe, there are two possible architectures applicable to MADIS that will promote an overall

centralized or distributed architecture for the NWS. The distributed configuration is depicted
below.
5.2.1 MADIS Recommended Configuration
Due to the expected demand from AWIPS users, it is likely up to 150 AWIPS station (and their
respective AWIPS Cube Interfaces) will request/subscribe data from MADIS. Therefore, to
avoid system bottlenecks, the Cube Interface should be placed closer to MADIS as opposed to
the centralized configuration serving MADIS datasets from the TOC Cube Interface.

NWS Graphic Product Group
The Aviation Weather Center (AWC) and NOAA Operational Model Archive Distribution
System (NOMADS) can provide the Forecast and Model products, respectively. The Model
Product group is split between the NOMADS-NCEP and NOMADS-NCDC servers (see NCDC
section below). The NWS Graphic Product Group is a set of RedBook graphics that are
produced from within the following NCEP‟s sub-organizations: Hydrometeorological
Predication Center (HPC), Storm Prediction Center (SPC), Aviation Weather Center (AWC),
NCEP Central Operations (NCO), National Hurricane Center (NHC), and Climate Prediction
Center (CPC).
5.3.1 NCEP Recommended Configuration
NOMADS is run at the Web Operations Center (WOC), and ingests data produced by NCEP.
There is also another NOMADS server located at the NCDC which will primarily be used by
AWIPS for data ingest. AWC is a sub-organization of NCEP. There are several configuration
options that can be ascertained from looking at the recommended configuration below.

5.4 National Climatic Data Center
The National Climatic Data Center (NCDC) is the world's largest active archive of weather data.
Their mission is to provide access to and stewardship of the Nation's resource of global climate
and weather related data and information, and assess and monitor climate variation and change.
For IOC, NCDC has datasets of interest for AWIPS and the FAA. In particular, the following
products MAY be provided by NCDC:
Model Product Group
Canadian Weather Radar
The Canadian products are sent over non-profit research networks from Environment Canada to
the NCDC (risq.net on the Canadian side, ncren.net on the U.S. side). Most of the model
products are generated within NCEP, and are sent for archival at the NCDC.

5.5 National Satellite Operations Facility
GOES-R is the next generation geosynchronous satellite constellation run by NOAA/NESDIS.
GOES-R will have an increase in data volume compared to its predecessor. This increase is
caused by improving the data resolution, increasing the number of products generated, and a
decreasing the scan frequency. In the IOC timeframe, the GOES-R Access Subsystem (GAS) is
the likely satellite data access point. At this point, only current operational products from GOES
E/W and POES have been identified for inclusion at IOC. The following product groups MAY
be provided via NSOF.

Currently, the FAA has not yet identified any of the new products made available through
GOES-R‟s additional onboard instruments.
5.5.1 NSOF Recommended Configuration
The Environmental Satellite Processing Center (ESPC), located at NSOF, is the consolidation of
separate GOES and POES satellite data processing centers. Currently, the ESPC is the prime
dissemination point for operational satellite products. Other systems, such as NOAA‟s
Comprehensive Large Array-data Stewardship System (CLASS), obtains satellite data via the
ESPC. In the IOC timeframe, GAS is being developed and integrated as a part of an enterprise
NESDIS Data Processing and Distribution operational capability; i.e., as a part of the NESDIS
ESPC, which makes it the likely IOC data provider.

6.2 Advanced Weather Interactive Processing System II
The Advanced Weather Interactive Processing System (AWIPS) is the system used by
NOAA/NWS to analyze and disseminate operational weather data, including time-sensitive,
high-impact warnings. AWIPS II consists of the current baseline functionality of the current
AWIPS system, but re-architected with a SOA design. The following product groups are
required by AWIPS:

implementing. The Contractor is not responsible for the hardware, or personnel needed at all
„AWIPS Cube Interface‟ locations. Proper documentation, specifically the Contractor‟s
proposed IRD/ICD along with the DCI (see Attachment E), is expected from the Contractor to
allow minimal effort for other organizations within the NWS to be a participant in the Cube.
Due to the evolving nature of AWIPS, the number of AWIPS Cube Interfaces can range from 1
