Synopsis

The NWS plans to start removing existing systems such as AFOS, SWIS (satellite display), and WSR-88D PUP during the AWIPS Build 4 timeframe. In order to accomplish this, AWIPS Build 4 must have the critical capabilities of these systems or their functional equivalents. AWIPS Build 4 is a joint development effort, with FSL, Office of Hydrology, Techniques Development Laboratory, and PRC all contributing software; only FSL requirements are addressed in this document. Highlights of this build are:

complete essential AFOS capabilities
complete PUP capabilities
complete initial LDAD capability

Objective

Provide NWS with a reliable, highly functional system, which can be used by forecasters and hydromet technicians to perform their duties and allow NWS to begin removing existing systems.

Replace AFOS Comms

ASOS interface - not sure on dial or dedicated (recommend not an LDAD function either way)
AWIPS Message Handling System (X.400)
- install
- add UI
- specify destination (distribution)
- specify priority
- schedule dissemination of products
- encode/decode messages for the PRC API
- interface to gateway message handling
- user request of data
- o request/reply -- limited, defined by ...
- o putting data to other sites
- make sure cannot put requests in a script
- limit to # of outstanding requests
- request time-out
- specify destination, ID of data to send out

Finish WSR-88D functions

Display all products
Make WSR-88D precip data available to OH
Maximum value method on mosaic for radar
Arithmetic operations on radar for VR shear (extend dis/sp of motion extensions)
PUP archive capabilities
- GUI for archiving
Digital Precip Array on nexrad
- OTR and display
RCM -- request and store text prod from radar (low)
Add priority to products on RPS list editor
SWA family - display and request
AAR (automatic alert request) retransmission
Product list message request?

Initial LDAD

Request/receive prods from different obs platforms
The site can automatically disseminate data to external users
Menu driven product requests for external users
The site can disseminate data to external users upon their request
Send designated hazardous products to appropriate, pre-approved external users selected by geographic areas affected by product...FAX also?
Site can define comms port interface characteristics (E-2,27)
ALERT/IFLOWS/AMOS/RAMOS/ROSA/ROSA DTMF/LARC/spotters interface
LDAD collecting of precip reports
- LDAD accept request for more frequent collections
- Hydro storage

System Enhancements

Revise purging capability -- by version, by time
- GUI for purging parameters
Notification to user when equipment fails
Commanded shutdown in one command (E-2/E-3)
- System shutdown interface (E-2.17)
- single command shutdown
- generate "shutdown" msg to NCF and user specified sites
Keep site status messages for 10 days (e-1.12)
Remove log partition dependencies such that system continues to operate properly even if log partition is filled

Graphics Workstation

delete color tables
new (UNIX version) Interactive skewT

Additional products

Time series (work with TDL)
Image arithmetic operations in product maker

Text Workstation

User sets value for watch/warning expiration alarm (low)
Add Extreme cold, extreme heat to warngen templates (C-7,53)
Capability to store and NOT forward
Prepare forecast products out of manually prepared data -- make zones more generic (C-9, 68)
Move journaling of text to data disks and allow recovery for any workstation from any other text workstation (F-5,57)
Add admin messaging to text workstation
- get PRC X.400 test drivers for sending messages
- 3.8 of MHS Integration Point document

Performance Enhancements

Informix tuning for combined application use

Other

Continue OI replacement (window resizing)
Identified bug fixes
Install ICWF?
Install firewall
Forecaster input to initiate warning mode for site
- (send message to NCF)
- (no automatic visual for mode)
Site Backup (service backup>??)
- send message to NCF
- Get radar data from backup site capabilities via dial-in
- automatic -- scheduled dial-up capability
- add an application to start a cron job for the dialin
Initial Review
- D-2 retrieve data from archive
- install omniback software
NWWS interface?
Integrate LAPS into revision control
investigate regional scale analysis (2000km x 2000km)

Documentation

to be determined

Schedule

June 30 - Requirements completed
July 12 - Task assignments made
December 12 - Development software freeze
December 13 - 27 - Testing and debugging of software load
Early January - Install in Denver

Functional Specifications

This section includes functional specs for each of the requirements above.

(This is only a short example.)

B.4 putting data to other sites

A UI needs to be developed to specify dataset and destination ID. An appropriate message will be constructed and submitted to the X.400 comms handler.

B.6 request/reply

A UI needs to be developed to specify dataset and ID of site from which to request it. An appropriate message will be constructed and submitted to the X.400 comms handler.
