Friends and Partners NBAA 2003 JoAnn Y. Ford Manager, Aerospace Weather Standards Division, ARS-200 Aerospace Weather Policy and Standards Staff
ASOS Preplanned Product Improvements (P3I)(FAA Priorities) • Processor Upgrade • Dewpoint Sensor • Ice Free Wind Sensor • Enhance Precipitation Identification • Improve Ceilometer & Sensor Algorithms • Improve Visibility Sensors & Algorithms • All Weather Precipitation Accumulation Gauge (AWPAG) • Snow Depth/Accumulation Sensor (Non-funded requirement)
FY04 FAA allocation for ASOS P3I is $4M - Total FY04 baseline ASOS funding is $9.125M • FY05 FAA allocation for ASOS P3I is $7.5M - Total FY05 baseline ASOS funding is $12.625M
ACU Processor Upgrades • Performance Parameter – Increase processing speed and memory to improve performance and allow new sensor upgrades • Processor prerequisite to PI sensor deployments • 135 of 883 installed as of 9/30/03 • Resolved Key Issue: a few sites were experiencing FAA/ALDARS Comms problems; now releasing additional processors for installation; est. all processors installed by 12/31/03
ACU Processor Upgrade NWS/FAA Current NWS Baseline Milestone
ASOS PI – Dewpoint Sensor • Phased deployment paced by ACU processor and FAA funding • 356 of 883 sites approved for phased deployment • 38 sites currently operating • 405 sensors delivered in 2002; 280 additional ordered September 2003 • Sensor performance to date is excellent

Enhanced Precipitation Identifier NWS/FAA Current NWS Baseline Milestone
Ceilometer Replacement NWS/FAA Current NWS Baseline Milestone
ASOS Configuration Control Board (ACCB) Initiatives (not all-inclusive list) • Change thunderstorm reporting range thresholds for SPECIs • Freezing drizzle algorithm • Connect NWS ASOS sites to ADAS for ITWS • Modify pressure sensor yes/no prompt • Delete RVRNO code
Automated Weather Sensor Developments • ALDARS Installation • ASOS RVR Modification • ASOS-ATIS Interface • Stand Alone Weather Sensors (SAWS)
Friends and Partners Initiatives General Discussion • SPECI transmission anytime – testing will be completed at initial sites in December 2003; deployment to all 883 sites will take several months • AOP/AAF-1 letter was signed; ADAS integration into National Airspace Performance Reporting System (NAPRS) • ASOS Internet availability • Perceived Tower and SFC VSBY Discrepancies version 0.05
