1 NAWIPS Migration Briefing to Development Collaboration David Plummer NAWIPS Software Development Team Lead NCEP / NCO 29 September 2010

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

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 3

What is NAWIPS? GEMPAK Foundation Libraries Application Libraries Device Drivers GPLT GEMPAK Apps / Local Apps (SFMAP, GDPLOT2, etc.) GUI Apps (NMAP, NSHARP, etc.) 4

Merging National Centers Perspective in CAVE –No changes to other perspectives (D2D, Hydro, etc.) NMAP2NTRANSNWXNSHARP AWIPS2 CAVE NC Perspective NAWIPS GUI Apps GEMPAK text Apps AWIPS2 Services (Database - read access only) 5

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 9

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 11

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 13

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 20

PGEN Products – Text products –Apply style sheet to XML –TCA (Tropical Cyclone Advisory) - 21 IRENE WATCH/WARNING BREAKPOINTS/ADVISORY NUMBER 1 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL AM AST FRI SEP HURRICANE IRENE FLZ /E.NEW.KNHC.TR.W T1200Z T0000Z/ 800 AM AST FRI SEP JUPITER-INLET-FL 26.95N 80.06W FERNANDINA-BEACH-FL 30.66N 81.44W $$ FLZ /E.NEW.KNHC.TR.A T1200Z T0000Z/ 800 AM AST FRI SEP CARD-SOUND-BRIDGE-FL 25.29N 80.37W JUPITER-INLET-FL 26.95N 80.06W $$ ATTN...WFO...CHS...MLB...MFL...JAX...ILM...

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 23
