SHOUT

Overview


Description

The Sensing Hazards with Operational Unmanned Technology (SHOUT) project is part of the NOAA's Unmanned Aircraft Systems (UAS) Program. The objectives of the SHOUT project are to:
  1. Quantify the significance of unmanned observations to high impact weather prediction through data impact studies using Observing System Experiments (OSE) based on unmanned observations collected during prototype operational field missions and Observing System Simulation Experiments (OSSE) based on expected unmanned observing capabilities.
  2. Quantify the cost and operational benefit of unmanned observing technology for high impact weather prediction through detailed analysis of life-cycle operational costs and constraints versus scientific benefit.
The overall goal of the SHOUT project is to demonstrate and test prototype UAS concepts of operations that could be used to mitigate the risk of diminished high impact weather forecasts and warnings in the case of polar-orbiting satellite observing gaps.

Overview

During 2015 – 2016, the SHOUT project funding will annually support approximately 14-20 NOAA-dedicated Global Hawk missions divided between western US coast deployments focused on Pacific and Arctic storms and eastern US coast deployments focused on tropical cyclones. The SHOUT Project Scientists are also exploring leveraging opportunities for NOAA-dedicated missions to be conducted in collaboration with 2016 NASA Global Hawk missions proposed for the NASA Earth Venture solicitation currently in progress.

The Global Hawk payload will be selected based on the data impact studies but expected candidates include sensor systems which provide information on vertical meteorological profiles and ocean surface winds. Potential candidates are Airborne Vertical Atmospheric Profiling System (AVAPS), High Altitude MMIC Sounding Radiometer (HAMSR), the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) and the Hurricane Imaging Radiometer (HIRAD).

Instrumentation

  • NOAA: AVAPS - Advanced Vertical Atmospheric Profiling System developed by NCAR, dozens of dropsondes for deployment at altitudes up to 65,000 ft from the unmanned Global Hawk aircraft collect high vertical resolution measurements of the temperature, pressure, relative humidity, and wind speed and direction in the atmosphere.
  • NASA: HIWRAP - High-Altitude Imaging Wind and Rain Airborne Profiler, radar designed to examine the factors of storm intensity: formation, structure and intensification.
  • NASA JPL: HAMSR - High Altitude MMIC Sounding Radiometer an atmospheric sounder intended for aircraft deployment is a microwave temperature and humidity sounder instrument that looks at the microwave spectrum and was designed and built at the Jet Propulsion Laboratory.
  • NASA GHRC: LIP - CAMEX-4 ER-2 Lightning Instrument Package consists of eight state of the art digital electric field mills and a dual-tube Gerdien conductivity probe; These field mills allow the determination of the vector components of the electric field to improve our knowledge of the electrical structure.

Geographic Coverage

Pacific, Arctic, and Eastern US coast.

Data Schedule

AVAPS data capabilities will be implemented in MADIS by June 30, 2015 and data will be available for all SHOUT flights that occur after this date. During missions the MADIS system will be collecting AVAPS information in near-realtime.

As the SHOUT team selects the timing for implementing the remaining sensor type data in MADIS this page will be updated to reflect the implementation schedule.

Volume

Payload for the UAS will be determined by the impact studies and also based on the weather event to be observed. The Global Hawk is capable of carrying 88 AVAPS for a single mission each AVAPS would be sending over 40,000 observation sample points.

Restrictions

No restrictions. All observations are publicly accessible.

WISDOM Balloon Winds

Overview


Description

The WISDOM program aims to improve the hurricane track prediction in the 3 to 7 day period before landfall by providing wind and atmospheric data in areas of the Atlantic basin that are poorly observed. NOAA, with major funding support from the DHS Science and Technology Directorate, conducted a successful initial feasibility test during the 2008 hurricane season with balloons reporting wind data in near real-time. WISDOM will conduct a Proof of Concept in 2009 to determine the long term hurricane track forecast improvements achieved by ingesting WISDOM data into global forecast models.

The WISDOM system is designed around the availability of small super-pressure balloons, and the availability of small (100 gram) electronics which include over the horizon Global Positioning System and satellite radio communications capabilities. The concept is that large numbers of WISDOM balloons with the GPS payload are released to optimize weather prediction at a future time for phenomena of interest.

Advanced techniques of assimilation and modeling are used to determine the release locations of the balloons to optimize their trajectories to improve future numerical weather prediction. A total of 88 WISDOM balloons were launched during the 2008 season - notably 57 balloons around Hurricane Paloma.

Overview of 2009 Operations

In 2009, with major funding support from DHS S&T, NOAA and the Air Force Weather Agency, the program will seek to quantify the forecast improvement provided by ingesting WISDOM data into numerical weather prediction models, including ESRL.s FIM model. Two major hurricanes threatening the US will be targeted for the WISDOM 2009 Proof of Concept deployments. In addition to providing wind data the 2009 WISDOM balloon system will also include termination devices and a pressure sensor. Up to 250 WISDOM balloon systems will be launched from up to ten sites in the continental US and overseas with the aim for improving numerical weather prediction. WISDOM balloons will be launched about 6-9 days in advance of the anticipated hurricane landfall at two altitudes, 12,000 ft and 26,000 ft. Two major tropical cyclones will be targeted for WISDOM launches during the operating season beginning on or about September 1, 2009 and ending on or about October 1, 2009. Data will be reported approximately every 30 minutes. The balloons will remain in the air for about 2-10 days.

MADIS users who request access to the WISDOM data will be sent an email when the launches occur. After the flights, the data will remain accessible from the MADIS archive of saved-real time data. The long term goal is to saturate the data void for every major storm with several hundred balloons in an attempt to measurably improve the 3 to 7 day hurricane forecast. Observations from these data void areas may significantly improve the 24 hour forecast, saving lives and property, conserve energy, and potentially save millions of dollars. WISDOM data should be considered experimental.

Geographic Coverage

Launch locations for the 2009 Hurricane Season:
  • Atlantic: Barbados; Azores; Dakar, Senegal.
  • Caribbean: Islamorada, FL; Puerto Rico; Bermuda.
  • US East Coast: Tybee CGS, GA, Wallops Island CGS, VA.
  • US Gulf Coast: Waveland, MS, Corpus Christi, TX.

Data Schedule

Data will be available in 2009 only during yet to-be-determined tropical activity periods in September. Reports will be available approximately every 30 minutes.

Volume

Data volume is expected to be low.

Restrictions

No restrictions. All observations are publicly accessible.
