7 Geospatial Information Systems Sea Ice Processing Analysis System ARCGIS 10.1 with tailored extension suite (SIPAS) for NIC. System ingests and processes various imagery sources into Geotif format. NIC receives Arctic Cap Nowcast/Forecast System (ACNFS) model data from NRL, files are converted into Geotiff format for display in SIPAS. NIC receives International Arctic Buoy Program (IABP) data from the ARGOS system, files are converted into shapefiles for display in SIPAS

8 GIS use at USNIC SIPAS provides egg tool that automatically converts data to SIGRID-3, an internationally agreed upon export format produced at numerous ice services. This vector file preserves all the data from original ice analysis and can be re-projected without loss of information. CTCC CACaCaSaSaFaFa CBCbCbSbSbFbFb CCCcCcScScFcFc CFFpFpFsFs CNSoSo CDSdSd

17 ACNFS for Special Support at USNIC ACNFS forecasted fields could improve the quality and awareness of ice conditions for tailored special support. "Products from NRL's Arctic Cap Nowcast/Forecast System (ACNFS)" Ice Exercises Resupply Missions Ice Camps/Field Campaigns

18 Fractures, Leads, and Polynyas (FLAP) Provide location and orientation/directional information on fractures, leads, and polynyas across a given region. ACNFS Illustration from NRL's Arctic Cap Nowcast/Forecast System (ACNFS) ICEX fracturing event with ACFNS Reversal in winds and ice drift was predicted 6 days out. Large-scale fracturing was predicted 48-hrs out. Can NIC use ACNFS to provide 1-7 day FLAP Outlooks?

19 Ice Edge Forecasting Apply ACNFS forecasted drift vectors (drift velocity and bearing) to current NIC observed ice edge 48-HR DRIFT VECTOR (ACNFS MODEL) CURRENT NIC ICE EDGE (OBSERVED) 48-HR PREDICTED AUTO-ICE EDGE 48-hr Forecasted Auto-Ice Edge * Experimental product, not currently operational

20 USNIC Tie-Points Project Goal is to improve ice prediction model outputs by provision of precise, high quality ice condition analysis at the model cell level. Sea Ice Concentration Confidence Level Date/Time Stamp of Image Quality feedback into the model to assist in model refinement and in return give back more accurate modeled information for the analysts.
