- 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.**
**-**** 20-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.**

**Important pressure mandatory levels are (mb):**
**1000, 925, 850, 700, 500, 300, 250**

## 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 1998-2001)**
**•**** ****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**
