Hurricane Research Division (HRD) Principal Investigator: Dr. Mark Powell Presented by: Sonia Otero Aircraft Operations Center (AOC) Real-time hurricane monitoring onboard NOAA aircraft Partnership of: with the Cooperative Institute for Marine and Atmospheric Studies (CIMAS)
Background - Every hurricane season, scientists of HRD participate aboard NOAA's hurricane research aircraft on over 200 hours of reconnaissance, surveillance and research of tropical cyclones. - The fleet, operated by AOC, consists of: 2 WP-3D Orion turboprops 1 Gulfstream IV jet - Aircraft instruments collect 1 Hz flight-level and Stepped Frequency Microwave Radiometer (SFMR) observations, and 2 Hz dropsonde data.
Background... - Local Ethernet network on aircraft - Real-time data are sent straight to the National Hurricane Center (NHC) through a 9600 baud satellite link year old aircraft measurement system provides limited plotting - Scientists of coordinated missions with multiple aircraft (NOAA, Air Force, NASA, Navy) have little measurement information from other planes.
About the data... MINOB: URNT40 KWBC NOAA3 WX02A BONNIE Second Data Interval time, position, pressure altitude, wind direction and speed, air and dew point temperatures, peak wind direction and speed, SFMR wind speed, SFMR rain rate
About the data... TEMPDROP: UZNT13 KNHC XXAA ///// AF A MARIE OB MXWNDBND SPL 2525N07835W 1826 LST WND 012 MBL WND Upper-level pressure, temperature, humidity and wind report from a sonde released by carrier. Important pressure mandatory levels are (mb): 1000, 925, 850, 700, 500, 300, 250
Currently, these are your “eyes” aboard a WP-3D:
Next season, we aim for Air Force SFMR aboard N43RF Orion WP-3D N43RF GPS dropsondes C-MAN marine Moored Buoys C-MAN land
Hurricane Katrina, August 29, UTC Air Force flying at ~2500m, NOAA 43RF at ~3000m.
Strategy a Linux server aboard 1 P-3 Orion that: a) acquires MINOB and TEMPDROP from local aircraft network. FTP to NHC brings additional data (2nd aircraft, buoys, etc.) b) maintains relational database to archive flight's local and foreign data c) hosts J2EE (Java 2 Enterprise Edition) Application server to support web client Scientists launch Java web application from their laptops connected to aircraft network
Progress (“So many hurricanes, so little time!”) Aircraft: MINOB and TEMPDROP distribution within aircraft network. Ground: Long-term open-source database (PostgreSQL) ready to archive local and SatCom data feeds. Java applet derived from code re-use of established HRD H*Wind application (HPCC supported ) Leading open-source J2EE Application server (JBoss) hosting Java applet
Future Steps * By January 2006, AOC will equip P-3 N42RF with: - a 64K baud SatCom link - a Linux server with the new display * First tests of system during winter storm experiments based on flights in the Pacific * In Spring 2006, use system in instrument calibration flights * Next hurricane season, it becomes a regular tool
Benefits - Comprehensive monitoring of all involved aircraft measurements in a mission - Increased onboard productivity and effectiveness to diagnose structure, dynamics, intensity - Ground truth measurements included for neighbor comparisons - Open-source approach facilitates standard and cheap software deployment
Realistic Potential Deployment on the other NOAA aircraft Plots of time series, profiles More Ambitious Add visualization of lower fuselage radar, and eventually of tail Doppler radar 3-D graphics more info:
