What is NAWIPS?

• Software suite that supports National Centers’ forecast operations and development activities– GUI and text-based apps– Includes local applications and scripts– Runs everywhere including CCS and Compute Farm– “Soup to nuts”

• Hardware independent– No specific hardware and few system software requirements

• Development team since 1992

2

What is NAWIPS?

• Software development follows an incremental, generalized approach– Support requirements of diverse customers

• HPC, OPC, CPC, SPC, NHC, AWC, SWPC• PR, AR, RFCs• UNIDATA

• Must bring functionality to the field quickly

• Strength is in foundation libraries– GEMPAK

What are we doing?

• Decoders– McIDAS : remapped as well as native projections (GVAR)– GRIB2 : movable grids, named storms, named dispersion models, etc.– Radar mosaic– AWW – advisory, watch, warning : FFA, SVRL, WARN, WCN, WOU,

WSTM, WTCH– SIGMETs : Conv, NConv, Int’l, AIRMET– WCP (watch corner point)– FFG– TCM (tropical cyclone)– NCSCAT : various scatterometer

6

What are we doing?

• National Centers Perspective - general– Combines functionality of 4 legacy GUI applications

• NMAP2 – data display and product generation• NTRANS – multipanel• NSHARP – vertical profile display, diagnostics and editing• NWX – FOS text product select and display

– Gray box conversion• Some variances unavoidable or negotiated

– Much development is new• Leveraged Raytheon implementations where possible

– Flexibility is key

7

What are we doing?

• National Centers Perspective - display– No “localized” spatial scales

– No “short fuse” driven interface• Heavy use of SPFs• Ability to adjust data request and rendering attributes prior to

loading

– Freely configurable via tables• Concept of “desk” (user -> desk -> site -> baseline)• Allows for pre-ops setup

8

What are we doing?

• National Centers Perspective - display– Flexible timeline

• Not restricted to current data• Archived data, case studies

– Multiple editors (tabs)• Leverage Eclipse RCP features• Unlimited number of animation sequences

– Configurable, multiple panes• Leveraged Raytheon framework• Temporal and spatial synchronization (or not)• Ensembles

10

What are we doing?

• National Centers Perspective – NSHARP view– SkewT-Hodograph Analysis and Research Program

– Profile display and analysis • Skew-T, wind profile, hodo• Animation

– Multiple data types• UAIR, PFC, [drops, grids, aircraft, …]

– Multiple pages of diagnostics• Configurable and expandable for additional development

– Interactive• User may adjust graphic (temp, dwpt, wind)• Adjustments reflected in diagnostics

12

What are we doing?

• National Centers Perspective – NWX view– FOS text data selection and display– Graphical selection– Identifiers are mapped into groups and individual products

• Real word interface• Public Products -> State Fcst Discussion, Zone Forecasts, etc.• NHC Products -> Outlooks, Hurricane Discussions, etc.

– Handles scheduled and unscheduled• Forecasts vs. Warnings

– Some products internally decoded for additional information• Graphical display• HPC QPF contours, UV Index

14

What are we doing?

• National Centers Perspective – PGEN view– Product Generation – “PGEN”– Generalized framework for (virtually) all operational products

• Text, images (web), grids, KML, etc.

– Highly configurable• Consistency for forecaster, consistency in products

– Drawing and editing capabilities

– Implemented in AWIPS2 as a “resource”• Operability simultaneous with any data• Should be accessible in other perspectives

15

Product Generation

• Basics– “Product-centric”

• Forecaster indicates what product is being worked• Palette, file names, layers, and other specs adjust to product• More than one product may be active

– Layers virtualized in the framework

– Control panel for active products and layers• Toggle display and rendering characteristics

– Time filtering available

16

Product Generation

• Objects– Drawable Elements (DE)

• Internal canonical XML implementation– JAXB

• Geo-referenced– Display projection irrelevant

• Foundation of primitive single- and multi-point Java classes– More complicated DEs extend primitive classes

• Rendering via Factory design pattern

17

Product Generation

• Objects– Primitives

• Fronts (all types), lines (numerous styles), symbols, combo-symbols, vectors (barbs, arrows, dir arrows, hash), markers, circles (ellipse), text

• Rendering attributes: color, line thickness, etc.

– Extended and compound collections• Jet, Aviation text, tracks, SIGMETs (international, convective, non-

convective, airmet), CCFP, Svr Wx Watch / Status / Cancel, Contours, Cloud, Turbulence, VAA, Tropical Cyclone Advisory (TCA), G-AIRMET, SPC Outlooks

• Attributes as needed

18

Product Generation

• Editing actions– Select– Copy– Move– Modify– Connect– Add point– Delete (DE, point, part, all)– Rotate– Flip– Interpolate– Extrapolate

19

PGEN

• Products - XML files

PGEN

• Products – grids– Any grid size / projection can be created from the Contour DE

• Contour DE is a collection of multi- and single-point DEs• Includes info about field (eg., parameter, level, valid time, etc.)• Includes default rendering information (eg., contour interval)

– Contour DE allows for relative minima and maxima– Extended graph-to-grid algorithm

• Includes minima / maxima• Includes “bounded area” processing

– wave height contours in Atl cannot influence pts in Gulf– SPC Outlook only within CONUS

• Includes optional discrete interval processing

22

PGEN

• Products – images– Save XML file– Run script containing GEMPAK program

• Input XML file• Set DEVICE driver to desired format (PS, GIF, etc.)

– Same XML file can produce multiple displays• Device driver and projection independent

– Most NCEP web images derived via this method
