7th ORM Report
Report of the Seventh Meeting of the
Ozone Research Managers of the
Parties to the Vienna Convention
for the Protection of the Ozone Layer
Michael J. Kurylo
Chairman, 7th ORM Meeting
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Background:
• The 7th meeting of Ozone Research Managers of the Parties to
the Vienna Convention was held in Geneva (18-21 May, 2008) in
accordance with decisions I/6 and III/8 of the COP.
• ORM Reports and the WMO-UNEP Scientific Assessments have
different purposes:
–
–
–
–
All are required under the Vienna Convention and Montreal Protocol
The Assessments enable the Parties to evaluate control measures
under the Montreal Protocol and are communication devices
between the research community (striving for better understanding)
and decision makers (seeking informed action)
The Assessments are neither policy recommendations nor research
planning documents but provide input for both
The ORM Reports, on the other hand, specifically address research
and monitoring needs in light of scientific understanding and make
specific recommendations to the Parties regarding international
actions for improved research coordination and networking

8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations
The recommendations were set against the following background
from the Scientific Assessment of Ozone Depletion: 2006
• Stratospheric ozone will remain vulnerable to chemical depletion
by chlorine and bromine chemicals for much of the current century
–
Ozone-depleting chemicals are projected to return to their “preozone-depletion” levels by the middle of this century for mid-latitudes,
with polar regions following suit about 20 years later
• While the rate of ozone depletion at mid-latitudes has slowed in
recent years due to the decline in EESC, polar ozone loss
remains large and is highly variable
–
–
projections of a changing climate will impact the stratospheric ozone
layer and its recovery
the connections between these two issues are currently being
explored by the science community

8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Background
The complexities of ozone and UV science require:
• Continuation and expansion of systematic measurement and
analysis capabilities for tracking the evolution of ozone- and
climate-related source gases and parameters.
• Detection and tracking the stabilization and expected
recovery of stratospheric ozone.
• Attribution of changes in radiation forcing to changes in the
ozone profile or to other atmospheric changes.
• Derivation of a global record of ground-level UV radiation.

Assessment of Ozone Depletion: 2006
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Research Needs
There are a number of new questions with respect to expected ozone
recovery from the influence of ODSs and the interrelationship between
ozone and climate variability and change. These require
• Studies to quantify the chemical, radiative, and dynamical factors
contributing to ozone layer evolution in a changing atmosphere
(including studies of the consequences of climate change mitigation
and adaptation strategies)
• Laboratory studies relating to ozone evolution and monitoring
• Studies to understand the emissions (natural and anthropogenic),
banks, and atmospheric evolution of ODSs, ODS substitutes, and
other climate-related trace gases (effects of climate change on
sources, sinks, and lifetimes)
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Research Needs
(continued)
• Studies to investigate the role and impact of changes in
stratospheric ozone and ODSs on surface climate and on
tropospheric processes
• Studies to investigate the influence of factors other than ozone (such
as cloud cover, aerosol abundance, albedo, and temperature) on
surface UV
• Studies of the effects of UV radiation exposure on human health,
ecosystems, and materials
• Development of new and innovative instrumentation, algorithms, and
analyses as a means of reducing measurement uncertainty and
increasing global observational capacity for ozone, UV, ODSs, and
related variables
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Systematic Observations
Such observations are critical to understanding and monitoring long
term changes in ozone and surface UV.
Surface Networks – Priorities
• Expansion in tropics, central Asia, and southern mid-latitudes through
the redistribution of measurements from highly represented areas
• Preference for Brewers for new ozone and UV monitoring expansion
• Expansion of Umkehr sites for upper stratospheric time series
• Continuity of in situ observations of ODSs, ODS substitutes, and
GHGs as well as of networks providing altitude profile information for
ozone- and climate-related species
• Increase in balloon sonde networks for ozone and water vapor
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Systematic Observations (contin.)
Satellite Networks – Priorities (recognition of a serious near term gap in
measurements of ozone and ozone- / climate-related species)
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Systematic Observations
(continued)
Satellite Networks – Priorities (recognition of a serious near term gap in
measurements of ozone and ozone- / climate-related species)
• Continuation of solar backscatter UV observations (ozone trends)
• High vertical resolution profiles for ozone and key molecules via limb
viewing (need to understand ΔO3 vs. ΔODS in a changing climate )
• Gap filling missions between current limb observations and future
missions (e.g. solar occultation FTS or limb viewing microwave for
high vertical resolution measurements of ozone and ozone-related
parameters)
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Systematic Observations
(continued)
Data Records – Priorities
• Systematic effort to understand differences between data sets derived
using different observational techniques
• Intercomparison campaigns to reduce systematic differences in
observations using identical and different techniques
• Analysis / archiving of existing (unanalyzed) data sets
• Reanalysis of data sets based on algorithm or analysis improvements
• Workshop in 2009/2010 on total ozone time series
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Systematic Observations
(continued)
Additional Priorities
• Infusion of new (more sophisticated) instruments in network
observations (establishment of Standard Operating Procedures)
• Documentation of spectroscopic parameters used for data analysis;
improved measurements of cross-sections for ozone and related
species
• Increased level of collaboration and coordination among various
observational networks
• International calibration structure for UV networks – NDACC protocol
example; improved coordination under SAG for UV Monitoring
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Data Archiving
Before being archived, data must be quality assured (i.e., of highest
possible quality and includes metadata required by users).
• Fully implement 6th ORM recommendations
–
–
–
Prompt data submission to WOUDC
Funding for archiving of raw data
Support for the re-evaluation of historical data sets
• Salvage (recovery and assessment) of historical data
• Development of standard data quality assurance procedures
• Enhance linkage among data centers (O3, UV, GHG, met products,
etc.) to ensure availability for validation and modeling efforts
• Archiving of data obtained from regional process studies for improved
accessibility
8th COP / 20th MOP; Doha, Qatar; 16-20 November, 2008
7th ORM Report
Recommendations: Capacity Building
There is an insufficient number of regional centers for research,
calibration, and training (especially in developing countries). Need to
expand global networks and develop competence and expertise in
developing countries and CEITs. Specifically,
• Extend global expertise in O3 and UV observations and research
• Increase participation in regional and international research and
assessments
–
–
–
Mechanisms for extended visits to institutions in developed countries
Participation in regional and international validation /intercomparison
campaigns
Support for attendance at conferences and workshops
• Provide resources for sustainable, long term operation of regional
centers
