**1.0 PROPOSAL INFORMATION**

1.1 Title of proposed activity

  -----------------------------------------------------------------------
  Polar Stratospheric Ozone Depletion and Future Changes

  -----------------------------------------------------------------------

1.2 Acronym or short form title of proposed activity

  -----------------------------------------------------------------------
  Polar Ozone

  -----------------------------------------------------------------------

+-----------------------------------------------------------------------+
| **1. Background**                                                     |
|                                                                       |
| As a part the International Geophysical Year in 1957, column ozone    |
| measurements were initiated at South Pole, Antarctica using Dobson    |
| spectrometers. The aim was to measure variations in ozone as a tracer |
| to study the dynamics of the Antarctic stratosphere. In 1985, the     |
| annual stratospheric ozone depletion over Antarctica - the "Antarctic |
| Ozone Hole"- was identified. In less than 5 years it was proven that  |
| the ozone hole was caused by human emitted fluorochlorocarbons (CFCs) |
| and the ozone hole has become a globally recognized "poster child"    |
| for showing how humans can cause global scale changes. The discovery  |
| of the ozone hole and its association with the CFCs was the key       |
| factor that led to the Montreal Protocol to ban CFCs and the first    |
| international treaty to preserve the environment. The Arctic          |
| stratospheric ozone changes, though lesser in magnitude than the      |
| Antarctic ozone hole, are by no means of lesser importance.           |
|                                                                       |
| **2. Proposed IPY Activities to Address Specific Questions**          |
|                                                                       |
| There are a number of scientific questions related to polar ozone,    |
| both in the stratosphere and troposphere, which we will address. They |
| include the following:                                                |
|                                                                       |
| 1\. What are the trends in the extent and intensity of the ozone      |
| hole? When are we likely to see the "recovery" of the ozone hole?     |
|                                                                       |
| 2\. What is the impact of ozone hole and Arctic ozone losses on the   |
| Earth's climate system?                                               |
|                                                                       |
| 3\. What is the contribution of the Antarctic ozone hole to           |
| midlatitude ozone changes? Will these changes be altered and how?     |
|                                                                       |
| 4\. What is the impact of polar ozone losses on the chemistry in the  |
| lower regions?                                                        |
|                                                                       |
| 5\. Are there indicators in the polar stratosphere that portend       |
| changes in the troposphere?                                           |
|                                                                       |
| 6\. What are the trends in tropospheric ozone concentrations in polar |
| regions?                                                              |
|                                                                       |
| 7\. What are the chemical processes and trends in polar marine        |
| boundary layer ozone destruction?                                     |
|                                                                       |
| 8\. What are the impacts of the changing mix of emissions and the     |
| changing climate gases on the changes in polar ozone levels?          |

    see Note 1)

  -------------------------------------------------------------- --------
  **Natural or social science research**                         X

  **Education/Outreach and Communication**                       

  **Data Management**                                            

  **Legacy**                                                     

  **Other Targets**                                              
  -------------------------------------------------------------- --------

6.  What significant advance(s) in relation to the IPY themes and
    targets can be anticipated from this project?

+-----------------------------------------------------------------------+
| 100 words max                                                         |
|                                                                       |
| By bringing together a wide range of scientists to focus on the total |
| ozone budget in the polar regions, it will be possible to address the |
| first 5 IPY themes. Information gained in addressing the first 5      |
| themes will provide input to Theme 6. Gaining a better understanding  |
| of the connections between polar stratospheric ozone processes and    |
| tropospheric ozone concentrations and trends in relation to           |
| anthropogenic emissions will provide for better predictors of future  |
| ozone concentrations in both the stratosphere and troposphere. One    |
| example of a crosscutting research opportunity is developing an       |
| understanding of the episodic, photolytic driven, total destruction   |
| of ozone in the marine boundary layer that occurs across the Arctic   |
| Basin in spring and summer, and the feedback of this destruction into |
| the free troposphere. The area of this ozone destruction rivals the   |
| area shadowed by the Antarctic ozone hole, but involves orders of     |
| magnitude less ozone.                                                 |

| Partners include scientists from the USA, Canada, Russia, Japan,      |
| European Union, among others. Facilities would include the monitoring |
| stations, e.g., Barrow, Alaska; Alert and Eureka, Canada; Zeppelin,   |
| Svalbard; Summit, Greenland; and South Pole. The project will be      |
| carried out in close collaboration with WCRP's SPARC project.         |

| The study of Arctic ozone would continue to draw from the data        |
| collected around the Arctic Basin as mentioned in 1.7 and similarly   |
| from the stations in Antarctica.                                      |

2.3 What significant logistic support/facilities will be required for
this project? Can these resources be usefully shared with other
projects? (see Note 4)

+-----------------------------------------------------------------------+
| 50 words max                                                          |

| There are ample and excellent facilities in and around the Arctic and |
| Antarctic to conduct the proposed activities. Many of the facilities  |
| are presently conducting measurements applicable to the goals of the  |
| proposed project and many would be amenable to shared and cooperative |
| activities.                                                           |
+-----------------------------------------------------------------------+

| The project will leave an enhanced intellectual pool of scientists    |
| attuned to more efficient means of collecting, transferring,          |
| archiving and analysing polar ozone data.                             |

**3.0 PROJECT MANAGEMENT AND STRUCTURE**

3.1 Is the project a component (established over the IPY 2007-2008
timeframe) of an existing plan, programme or initiative or is it a new
autonomous proposal?

  --------------------- -------------------------------------------------
  New Project ? No      Component of an existing or planned activity ?
                        Yes

  The seeds of Polar    
  Ozone project were    
  sown in the IPY       
  (1958) and have now   
  grown into a many     
  faceted international 
  research community.   
  This new activity     
  will be a             
  coordinating and      
  focusing of talents   
  and resources that    
  already exist.        
  --------------------- -------------------------------------------------

2.  How will the project be organised and managed? (see Note 6)

+-----------------------------------------------------------------------+
| 100 word max                                                          |
|                                                                       |
| The ongoing polar ozone monitoring programs and associated research   |
| activities operated by the United States, Canada, Japan, Norway,      |
| Russia and Germany, to name a few, will in all likelihood continue    |
| their present operations through and beyond the IPY. The new          |
| activities proposed herein will be initiated and coordinated by Drs.  |
| A. Ravishankara, NOAA/Al and Russ Schnell, NOAA/CMDL, Boulder,        |
| Colorado who will form an international coordinating group from       |
| interested scientist involved in polar ozone monitoring and research. |
+-----------------------------------------------------------------------+

3.3 What are the initial plans of the project for addressing the
education, outreach and communication issues outlined in the Framework
document? (see Note 7)

+-----------------------------------------------------------------------+
| 50 words max                                                          |
|                                                                       |
| We will use international scientific meeting and reviewed papers to   |
| distribute the scientific results of the program, and popular media   |
| and agency outreach facilities to reach the general public.           |
+-----------------------------------------------------------------------+

3.4 What are the initial plans of the project to address data management
issues (as outlined in the Framework document)? (see Note 8)

+-----------------------------------------------------------------------+
| 50 words max                                                          |
|                                                                       |
| Most of the programs we envision participating in this activity       |
| already submit their data to the requisite World Data Centers. We     |
| will encourage those that do not, to do so in a timely manner.        |
+-----------------------------------------------------------------------+

3.5 How is it proposed to fund the project? (see Note 9)

  -----------------------------------------------------------------------
  Most of the polar ozone monitoring and research programs are nationally
  funded. We propose to seek modest additional funds to provide
  coordination services, planning for coordinated polar measurements, and
  for holding a special session at an international scientific meeting.

  -----------------------------------------------------------------------

3.6 Is there additional information you wish to provide?

+-----------------------------------------------------------------------+
| 100 words max                                                         |
|                                                                       |
| This project will grow substantially as eth coordinators canvass      |
| interested parties and define specific plans to address the           |
| scientific questions posed in 1.3.                                    |
