Overview

  • SEC in the National Weather Service
  • Primary SEC Objectives
    • Research/models to Operations
    • Operational Solar Wind Monitor
    • Operational Coronagraph
  • Aviation Support
slide3

SEC Joins National Weather Service (NWS) as one of the official National Centers for Environmental Prediction (NCEP).

  • NCEPs include:
          • National Hurricane Center
          • Severe Storm Center
          • Space Environment Center
          • …more
  • SEC joined NOAA’s NWS on 2005 January 9. NWS responsibility now extends from “Sea to Sun.”
    • There are NWS processes which affect SEC and the issuance of new products
  • American Meteorological Society (AMS) has welcomed space weather into its fold
    • Third Special Symposium on Space Weather in Jan 2006
slide4

09 Sep 2005: NWS Director, D.L. Johnson, briefed space weather conditions to NOAA Chief of Staff (Scott Rayder), who in turn briefed the General Counsel (Stan Sokul) of the Office of Science and Technology Policy in the White House.

Space Weather is now included in the daily and weekly NWS reports to NOAA and DOC leadership

Space Weather UpdateNOAA sunspot group 808 stayed very active this week and produced several significant solar flares (up to R3 on the NOAA Scale). The strong (S3) radiation storm that started Sep 8 ended on Sep 11. Moderate to strong (up to G3) geomagnetic storm conditions were observed from Sep 12-15. During this period, aurora was visible as far south as Colorado and Lajes Field, Azores, Portugal.

Principal SEC Goals through 2012

  • Transition research understandings and models to operations
    • There is new emphasis in NOAA on research-to-operations transitions; joining NWS has allowed us to ask for additional manpower to implement model transitions.
  • Establish an operational solar wind monitoring program
    • SEC has requested again that NOAA step up to this requirement; the decision is not yet made; however, steps in the right direction are in motion.
  • Fly a space-based coronagraph dedicated to operations
    • SEC has requested again that NOAA step up to this requirement; as yet, the decision is not positive, but again, efforts are in motion.
slide7

NOAA’s Space Weather Program FY2008

Program Baseline Assessment

Space Weather Program constraint #1

– Regional space weather forecasts and the transition of models and related research into operations

The need- Customers operating on continental and sub-continental scales are demanding regional specification and forecasts of space weather.

The Response - NASA, NSF, and DOD have expended tens of millions of dollars to develop models of the local and regional reaction of the space environment to forcing inputs from the Sun; many of these models are now mature and ready for transition to operations.

The Problem - NOAA’s Space Environment Center (SEC) has been unable to fund transitions of these critical models. Lack of resources constrains NOAA’s ability to deliver what customers want.

slide8

Status of NOAA’s efforts to get an operational solar wind monitor

  • NOAA management have agreed that we need a solar wind monitor.
  • Broad Area Announcement (BAA) issued in July 2005 for proposals.
  • - Three of these proposals were selected
  • in September 2005 and will be funded for a more detailed feasibility study ($100 – 300k).
  • NOAA hope to have reliable estimates in 3-6 months. Commercial solution is an option. Funding is still an issue!!!

So how do we convince the decision makers?

slide9

Total (estimated) Number of Space Weather Models Driven or Validated by ACE Solar Wind Data

  • Solar wind driven models and operational products are expected to grow considerably in the next decade.
  • ACE data directly drives five of the eleven SEC space weather watches and warnings, and influences the remaining six

NOTE: The plot above does not include many of the research efforts underway that rely on solar wind data

slide10
Average Monthly NOAA/SEC Internet Traffic and Customer Summary

Web Site: More than 30 million files transferred each month.

  • ~500,000 files created monthly with near-real-time data for 176 products
  • more than 250,000 unique customers per month
  • customers from 150 countries
  • NOAA/SEC has end-to-end system responsibility for universally used space environment data acquired by the GOES and POES environmental satellites. SEC also supplies real time solar wind data from the NASA ACE satellite.
  • A million ACE solar wind files are downloaded from the SEC FTP server every month by nearly 25,000 unique customers
  • SEC's public internet serves 4.8 million ACE RTSW data display files every month.

All the above numbers reflect monthly usage near solar minimum!

slide11

Annual Number of Space Weather Products Issued during Solar Cycle 23

  • The number of products above does not include the NOAA POES and GOES, or NASA ACE real time solar wind data sets, which account for over 14 million file transfers per month
  • Over 400 event-driven products were issued during each of the solar “minimum” years (1996 & 1997)

Status of NOAA’s efforts to get an operational coronagraph

PPBES - It is proposed to fly a coronal mass ejection imager (CMEI) on GOES-R series.

Coronagraph imagery is expected from NASA’s SOHO and STEREO satellites until about 2011. Then, CME images will cease, as NASA has no plans to fly a replacement coronagraph.

SOHO/LASCO

This need has been accepted as valid by the GOES-R project, as reflected in the GOES Mission Requirements Document (MRD) and Program Requirements Document (PRD).

However, the CMEI has been deemed unaffordable by the GOES-R project. It is not manifested for flight on GOES-R, although it is listed as a high priority Pre Planned Product Improvement (P3I) if additional money becomes available.

Aviation Support

The January 20, 2005 Radiation Storm, once again, caused impacts:

“Its been nasty …. The S3 (NOAA Scale) two days ago resulted in less optimum polar routings to Polar 4 rather than Polar 3, and lower flight levels. All this increases fuel requirements and reduced revenue payload. In addition, because of the effect on HF comms, we have abandoned polar today altogether. We must stop our Chicago to Hong Kong in Anchorage because no other routes provide non-stop capability.”

G. Cameron, Dispatcher, United Air Lines

United Airlines identified space weather as the #1 concern during polar operations

slide17

The September 2005 space weather also caused considerable impacts:

The New York Comm Center reported:

07Sep 1800Z:   Solar activity severely impacted all HFcomms.  Higher frequencies utilized with little effect.  24 aircraft position reports and NYC ATC messages were relayed via sat-voice between 1040Z and 1939Z. Severe operational impact. 

The San Francisco/SFO Comm Center reported:

07Sep 1755Z:  SFO sends ARINC Solar Flare Activity Advisory of moderate to severe impact to HF comms to airline customers.   SFO experiencing extreme HF "white-out“ conditions virtually wiping out all Pacific HF. 

11Sep   0050Z: Tokyo and Port Moresby Radio having difficulties, SFO will assist as needed.  13Sep   1930Z:    Solar activity severely disrupting HF comms in all Pacific areas throughout daylight hours.  Severe communication impact and severe operational/service impact. 

Major airlines rerouted flights away from the poles because of current and anticipated space weather conditions. This occurred several times during the September activity. These costly reroutes (~$100k) require an additional fuel stop and new crew.

slide18

Aviation Support

  • At the request of the commercial aviation community, SEC has hosted three workshops
    • April 2002
    • February 2004
    • April 2005
  • The outcomes have been:
    • a better educated user community
    • SEC’s better understanding of the plans and needs of the commercial aviation community
    • understanding of the plans for commercial vendors of services to the airlines
    • a path for SEC to provide appropriate products and services
growth on polar routes

The advent of new long range aircraft such as the A340-500/600, B777-300ER and B777-200LR

  • China’s aviation industry is developing at an explosive pace:

On June 18, 2004, the US and China concluded a bilateral air services agreement, permitting a nearly 5 fold increase in weekly frequencies over the next 6 years.

 Airlines operating China-US routes go from 4 to 9  Number of weekly flights from 54 to 249 over the next 6 years.

The Transportation Dept estimates the economic impact of the agreement at $12 billion in additional revenues for US carriers over seven years. - IATA

GOES-N Launch (sometime soon…we hope!)

  • GOES-N launch, originally scheduled for May 2005, has been postponed several times and is now scheduled for a Feb 2006 launch.
    • GOES-N features another Solar X-ray Imager (SXI)
    • Improved Energetic Particle Sensor (EPS)

- Protons 80 keV – 700 MeV (16 channels)

- Electrons 30 keV – 4 MeV (8 channels)

    • First-ever operational Extreme UltraViolet Sensor (EUVS)
  • It will likely be some time (years) before GOES-N is turned on.

Summary

  • The need for space weather services is growing at a substantial rate.
  • ACE, GOES, and POES data usage is growing steadily.
  • Real time solar wind data is essential. Space weather services cannot meet customer expectations without these measurements.
  • The aviation community’s need for space weather support will play a critical role in SEC’s future.
