Research Highlight

Surface ozone characterization at Larsemann Hills and Maitri, Antarctica

Study on surface ozone measured at Larsemann Hills and Maitri (Antarctica) during 28^th ISEA are presented.
Daily average ozone concentration varied from ~13 to ~20 ppb at Larsemann Hills and from ~16 to ~21 ppb at Maitri.
Photochemistry and transportation contribute partially to the ozone concentration at both stations.
Activated halogens as well as photochemistry provide sink mechanism occasionally to ozone at Maitri.
In case of blizzard occurrence, removal of ozone becomes more effective through chemical scavenging and deposition.

Participation in National and International collaborative programme:

1. Assessment of Air Quality in Lumbini Protected Zone: Phase 1-4 (July 2012-November 2013): WHO, Nepal and IITM collaborative project which were executed during July 2012-November 2013. The objective of the project was to assess air quality in Lumbini Protected Zone (LPZ), a global heritage location of Nepal, and develop air quality index for Nepal. The program included field campaign for measurement of air quality parameters during winter, pre-monsoon, monsoon and post-monsoon seasons.

2. Bay of Bengal and Monsoon Experiment (BOBMEX) Project: A DST Project organized during July-August 1999 to study the role of the Bay of Bengal in monsoon variability. Rain water and Aitken Nuclei samples were collected by our group on board ship ORV Sagar Kanya over the Bay of Bengal under this project to help meet the objectives of the project.

3. Chemical Research and Environmental Needs (CREN) Projects : An Indo-Swedish collaborative project on ‘Atmospheric Chemistry’ during 1992-1999, in order to study the chemical composition of wet/dry deposition at Pune (urban) and Sinhagad (a high altitude rural location near Pune). The collaboration was between IITM, Pune and Stockholm University, Sweden.

4.. Biogeochemical cycles in Himalayan Eco-system: A project in collaboration with G.B. Pant Institute of Himalayan Environment and Development, Kosi, Almora, India for studying the levels of particulate and gaseous pollutants and chemical composition of precipitation in the Himalayan region during 1993-2000.

5. Indian Ocean Experiment (INDOEX) Project: Surface observation of aerosols and trace gases during INDOEX FFP (First Field Phase) 1998 and IFP (Intensive Field Phase) 1999.

6. Arabian Sea Monsoon Experiment: Participated in the ORV Sagar Kanya Cruise No. SK-178 and SK-179 during June-August 2002 for the measurement of ozone of Aitken particles and for collection of TSP samples, size segregated aerosol samples and wet/dry deposition samples over the Arabian Sea. After performing chemical analyses of these samples, the data so generated have been used to understand physical and chemical characteristics of aerosols and their transport over the Arabian Sea from the source region.

7. Studies of Aerosols, Trace Gases and Precipitation Chemistry in Different Environments- A DST Project: Observation of aerosols, trace gases and wet/dry deposition samples at Pune, Delhi (New Rajinder Nagar-a residential location, and Okhla- an industrial location) and Darjeeling, a high altitude location in north-east India, during summer and winter seasons 2001-2004.

8. Composition of Asian Deposition (CAD) Project: A project in collaboration with Swedish Meteorological Institute, Stockholm, Sweden for understanding aerosol characteristics at Pune and Sinhagad through the collection and analysis of aerosol and wet/dry deposition samples at the respective locations during 2001-2004.

9. Land Campaign Program (2004): A multi-institutional effort organized in the year 2004 and funded by Physical Research Laboratory, Ahmedabad basically for the inter-comparison of various instruments of air pollution measurements utilized at different organizations in India and to have joint efforts in the area of air pollution studies. The project completed in two phases. The first phase covered the southern part of India during summer season and the second phase covered the northern India during winter season.
