2. SELECTED RESULTS FROM OBSERVATIONS AND ANALYSIS
● Analysis of a southern sub-polar short-term ozone variation event (Orte et al., 2019)
6
Left-top: MWR location (blue dot, OAPA) and MLS measurement location (yellow crosses) used in the inter-comparison. The numbers below crosses indicate the quantity of MLS measurements. Left-center: Time series of MLS (red
dots) and MWR (blue dots) ozone mixing ratios for three altitudes: 27, 37 and 65 km between October 2014 and December 2015 (the MWR was inoperative during March and July 2015 due to technical problems). Left-bottom: Atypical
event of Antarctic ozone hole influence over Río Gallegos. (a) Time evolution of the MWR ozone mixing ratio at 27 km (red line) and 37 km (blue lines). Light red and light blue areas represent the ozone mixing ratio zonal climatology at
both altitudes calculated using the MLS database (2004–2016). (a) Time evolution of the total ozone column measured with the ground-based SAOZ instruments (green dots) and OMI (purple dots) in Dobson units. White line and grey
area represent the climatology and 1-SD calculated using the OMI database (2004–2017). (b) Time evolution of the daily maximum Ultraviolet Index measured with the YES UVB-1 ground-based solar radiometer at the OAPA. White line
and grey area represent the climatological UVI at noon in Río Gallegos. Right: Advected potential vorticity maps assimilated with the MIMOSA model. Maps show the evolution of the polar vortex for two isentropic levels with potential
temperatures of 675K (left) and 950K (right).
● Insights of total ozone recovery inside the Antarctic vortex (Pazmiño et al., 2018)
7
Left: Evolution of total ozone of MSR-2 dataset inside the vortex averaged each year on 15 September–15 October period for different classifications: standard method at 475 and 550 K represented by black and blue lines, respectively,
and method considering the 400–600 K altitude range by the red line. Error bars represent twice the standard error. Right: As in left figure, but only for 400–600 K classification on different periods: September and mid-September to mid-
October. Error bars represent 2-std.
● Ushuaia GAW Station under ozone hole conditions during year 2019
The Argentine Ushuaia GAW Station is placed at the southern continental South America. Both total ozone column with Dobson spectrophotometer and vertical ozone profile with ozonesondes are part of its regular measurement
program.
Dobson spectrophotometer #131 measurements at Ushuaia during year 2019 (red). Left: daily ozone column compared with the average (1994-2018), including several days (3 to 10 and 14 to 16) of September 2019 with Antarctic ozone
hole overpass denoted with values below 220 DU. Right: monthly mean values.
8
Ozone (blue) and temperature (red) vertical profiles from ozonesondes at Ushuaia for six days of September 2019 including Antarctic ozone hole overpass in days 03, 09 and 16 September 2019 (total ozone of 187.7, 201.7 and 182.0
DU, respectively), evident in the ozone depletion in altitudes between 15 and 19 km.
3. THEORY, MODELLING, AND OTHER OZONE RELATED RESEARCH
● Modelling of the stratospheric dynamics is accomplished mainly in collaboration with the Laboratoire Atmosphère, Milieux, Observations Spatiales (LATMOS),
Centre National de la Recherche Scientifique, France, through the use of the Modélisation Isentrope du transport Méso-échelle de l’Ozone Stratosphérique par Advection
(MIMOSA). Contacts in this subject: Dr. Elian Wolfram ([email protected]), Dr. Pablo Facundo Orte ([email protected]).
● Modeling of UV radiative transfer in the atmosphere based on 1-D codes using principally the Discrete Ordinates algorithm with semi-spherical correction in
the direct component, which is useful for cases of homogeneous-layers composition of the atmosphere. Applications include the SMN daily forecasted UV Index. Contacts
in this subject: Dr. Eduardo Luccini ([email protected]), Dr. Elian Wolfram ([email protected]), Lic. Fernando Nollas ([email protected]), Dr. Pablo
Facundo Orte ([email protected]).
4. DISSEMINATION OF RESULTS
4.1 Data reporting
SMN and CEILAP send regularly their data (ozonesondes, UV-B Radiation, total ozone column, surface ozone, Lidar profiles) to the corresponding global
gathering centres: WOUDC (Canada), WDCGG (Japan), NILU (Norway), etc.
Data obtained by Pandora MAX-DOAS instruments are sent to the Pandonia Global Network (https://www.pandonia-global-network.org/). These data are used
to validate satellite data (Sentinel 5P - ESA).
Data from the Ozone Differential Absorption Lidar of Rio Gallegos station are regularly submitted to the Network for the Detection of Atmospheric Composition
Change (NDACC/NOAA).
4.2 Information to the public
SMN UV daily forecast web site was updated in 2018 adopting both the official World Health Organization risk color scale and risk numeric scale, including the
implementation of a novel tone degradation for UV Index values larger than 11 up to the highest registered on the Andean Plateau reaching values of 22 or even higher
(See figure).

Maps of SMN daily forecasted UV Index around solar noon for Argentina (http://www.smn.gov.ar/), day 09 March 2020. Left: for uncovered direct sun and Right: the expected average UVI including the forecasted noontime cloud field
along the country.
Additionally, SMN implemented since 2016 the real-time online availability of UV Index measured by UVBiometers at their stations of Buenos Aires and
Ushuaia (presently in update process for the new SMN web platform)
10
Real-time online UV Index measurements at Buenos Aires (Left) and Ushuaia (Right) stations during 08 March 2017.
SMN elaborates seasonal Ozone Hole Bulletins during the Southern springtime for dissemination in Latin-America (Four bulletins and one final report).
https://www.smn.gob.ar/sites/default/files/Boletin%204%20Agujero%20de%20Ozono%202019.pdf
SMN also translates the WMO Ozone Hole Bulletin into Spanish and puts it at the disposal of the Spanish speaking countries.

6. IMPLEMENTATION OF THE RECOMMENDATIONS OF THE 10th
OZONE RESEARCH MANAGERS MEETING
Commitment with the Montreal Protocol:
○ Argentina has ratified the Kigali Amendment (2016) to the Montreal Protocol. On November 22, 2019, the Instrument of Ratification was presented and deposited
with the United Nations Treaty Section. Pursuant to Article IV, paragraph 4, the Kigali Amendment entered into force for the Argentine Republic on the 90th day
after the date of deposit of the instrument, February 20, 2020, becoming the 89th Party to ratify the Kigali Amendment.
Calibration and comparison activities:
○ Accomplishing its responsibilities as WMO South-American Regional Calibration Center (RCC-III), the SMN Buenos Aires Central Observatory acted as
headquarters for the three main calibration activities on ozone-related parameters: V Comparison of Surface Ozone Analysers (October 2017), V Erythemal UV
Radiometers Intercomparison (2018), and IV International Comparison of Dobson Spectrophotometers (March 2019). Additionally, the Pandonia Global Network’s
in-situ campaign of maintenance and calibration of the Argentine Pandora instruments was developed at stations Buenos Aires, Comodoro Rivadavia, Bariloche
and Pilar (November 2018).
Collaborations and participation in international projects:
○ Active participation in the creation of the project Tropospheric Ozone Assessment Report (TOAR) (IGAC-NOAA-WMO), to generate easily accessible, documented
data on ozone exposure and dose metrics at hundreds of measurement sites around the world (urban and non-urban), freely accessible for research on the global-
scale impact of ozone on climate, human health and crop/ecosystem productivity. https://igacproject.org/activities/TOAR. SMN contributed with surface ozone data
to the Tropospheric Ozone Assessment Report (TOAR) (https://join.fz-juelich.de/access/).
○ SMN contributed with surface ozone data in near-real-time for the validation of analysis and forecast of global atmospheric composition developed by the
Copernicus Atmosphere Monitoring Service (CAMS), European Union.
Attendance at international training courses:
○ GAWTEC 31th training session, October 30th - November 12th, 2016. Main topics: UV radiation. Data handling and quality assurance. Precipitation chemistry (&
sampling). 15 years of GAWTEC celebration. Attending from Argentina: Lic. Fernando Nollas (SMN - Mendoza Station).
○ GAWTEC 32th training session, April 30th - may 13th, 2017. Main topics: Greenhouse gases (esp. CO2, H2O, SF6, CH4). Data handling and quality assurance.
Attending from Argentina: Mr. Jonathan Ferrara (SMN - Buenos Aires Central Observatory at Villa Ortuzar).
○ GAWTEC 34th training session, May 13th - 26th, 2018. Main topics: UV Radiation. Data quality assurance and control. Attending from Argentina: Mr. Hernán
Salutto (SMN - Pilar regional GAW Station).
Prevention of UV radiation effects on human health:
○ National Campaign for the Prevention of Skin Cancer. Developed by the Argentine Society of Dermatology. November of years 2017, 2018 and 2019. Participating
more than 220 health centers along the whole country. (http://www.cancerdepiel.org.ar/).
Historical milestones:
○ November 2019: 25th anniversary of Ushuaia GAW Station.
○ October 2019: 54th anniversary of continuous total ozone column measurements at SMN Central Buenos Aires Observatory (Dobson #097 1965-2010, except
years 1992-1993 replaced by Dobson #099, followed by Dobson #070 2010-present.
○ October 2019: 32th anniversary of the start of Dobson spectrophotometer (#099) measurements at Antarctic Marambio Station.

○ July 2019: 113th anniversary of the SMN Central Buenos Aires Observatory, presently WMO South-American Regional Calibration Center (RCC-III).
7. FUTURE PLANS
Principal objectives for period 2020-2023
○ Maintain the activities of monitoring ozone and UV radiation existing in the Argentine territory.
○ Planify and execute calibration tasks for Dobson instruments and UV radiometers to maintain traceability of measurements associated with these instruments with
the World Calibration Centers. This activity would require the help and support of the WMO.
○ Consolidate an inter-institutional committee formed by the principal investigators of the primary institutions that today carry out the monitoring of ozone and UV
radiation in Argentina.
○ Carry out a series of periodic meetings by this committee with the aim of expanding activities related to the ozone problem and its relationship with Climate Change
in our region. It is proposed to set the first meeting for the first half of the year 2021 in the dependencies of the National Meteorological Service (Headquarters).
○ Promote awareness activities and responsible use of the sun by implementing the inter-institutional UV risk management protocols in force in Argentina.
8. NEEDS AND RECOMMENDATIONS
● The first need at present for Argentina is to maintain their current monitoring networks in qualified operation. Argentina is aware of the importance of their data in
view of the strategic geographical location to study the atmospheric ozone problem, and will continue supporting with their own funds many of the activities in this
sense to maintain their databases within high quality standards, but coordination and support from the international scientific and funding institutions is primordial to
avoid declives up to a critical situation.
● Additionally, Argentina is making their own efforts to develop sophisticated instruments that contribute to widen their present networks, such as atmospheric Lidars,
whole-sky cameras, etc., some of them in strong international cooperation.
● Training courses and scientific workshops on ozone- and UV- related international activities and support should be maintained, devoted specifically to developing
countries, and particularly to Region III South America.
Other scientific concerns are still common to previous reports and must consider the strategic geographical location of Argentina to study and to understand the
consequences of this global environmental problem:
− Antarctica and Southern South-America must be still for many years considered the most critical region in the world related to ozone depletion and its
consequences.
− The Antarctic Ozone Hole must be continuously monitored by all means for many years. Permanent ground-based and satellite-based instruments are an essential
complement for this task.
− There is growing evidence that the ozone layer is both acting in response to current climate variability and change as well as affecting climate over the Southern
Hemisphere. Such coupled studies are an important component of understanding needed to assess climate variability and climate change processes. Hence it is
important to strength all atmospheric measurements relevant to both processes. This also requires a strong support in capacity building at the technician and
research levels to continue both with monitoring and relevant research.
− It is essential that research activities being enhanced regionally and globally in the double-pronged aspect of ozone depletion and variability within the framework of
Climate Change due to the many joint aspects and couplings that are starting to be understood. Hence it is essential to sustain national and international projects
regarding these as relevant issues.
− Until the recovery of the ozone layer does not become evident and sustained in time and as long as the international scientific community does not have a clear and
fully developed picture of the linkages between the ozone layer, the stratosphere and the troposphere, within the scope of climate change and variability such
research must be supported nationally, regionally and internationally.
