1. INDOFLUX NETWORK POSSIBLE CONTRIBUTION OF RRL BHUBANESWAR DR. G. ROY CHAUDHURY SCIENTIST REGIONAL RESEARCH LABORATORY, BHUBANESWAR

2. Comparison of different greenhouse gases

3. WORK DONE AT RRL • GROUP WORKING IN GHG SINCE 1991 • PART OF NATIONAL METHANE CAMPAIGN, METHANE ASIA CAMPAIGN, ASIAN LOW-COST GHG ABATEMENT TECHNOLOGY, NATIONAL COMMUNICATION TO UN FRAMEWORK CONVENTION on CLIMATE CHANGE etc. • GHG FLUX COLLECTION, SOPHISTICATED ANALYZER & PORTABLE DATA COLLECTORS AVAILABLE

4. WORK DONE AT RRL • DRY & WET PRECIPITATION CHEMISTRY AT RURAL BACKGROUND SITE SINCE 1996 – LONGEST RECORD ON FORESTED AREA IN INDIA • AEROSOL COLLECTION & ANALYSIS THROUGH PASSIVE AND ACTIVE COLLECTORS • EFFECT OF ATMSOPHERIC POLLUTION – CORROSION OF STRUCTURAL MATERIALS

5. INTERNATIONAL COLLABORATIONS • METEOROLOGY INSTITUTE, STOCKHOLM UNIVERSITY, STOCKHOLM • SWEDISH ENVRIONMENTAL LABORATORY, GOTHENBURG • MATERIALS CORROSION INSTITUTE, STOCKHOLM • COMMITTEE ON ATMOSPHERIC PRECIPITATION – STEERING COMMITTEE MEMBER • SCIENTIFIC MEMBER, MALE DECLARATION

6. FACILITIES & EXPERTISE AUTOMATIC WETONLY & BULK COLLECTORS

7. PASSIVE AEROSOL COLLECTORS

8. ACTIVE AEROSOL COLLECTORS – DENUDERS

9. AUTOMATIC WEATHER MONITORING STATION SOLAR CELL/BATTERY OPERATED DOWNLOADED AT REGULAR INTERVALS TO A LAPTOP * TEMPERATURE * WIND DIRECTION & SPEED * RELATIVE HUMIDITY * RAIN FALL

10. INSTRUMENTAL FACILITIES • STATE-OF ART EQUIPMENTS • GC WITH METHANIZER • IC . XRD/XRF • ICP-MS . NMR • SEM . TEM • AETHALOMETER • GRIMM’S SPECTROMETER

11. IMPORTANT FINDINGS • GHG emission from rice and pulse cultivation • Rice Methane E SIF 3.3gm/m2 Rainy season 1.97gm/m2 Kharif season NO2 0.01 mgm/m2 7.11 mgm/m2 Pulses 3.38-4.1 NO2

12. IMPORTANT FINDINGS • Factors affecting • Soil temperature • Fertiliser addition • Soil redox potential • Soil organic content

13. IMPORTANT FINDINGS • WET AND BULK COLLECTOR 6.6 AND 7 µEQ/LT RESPECTIVELY ACID VALUE. THE VALUES OF ANIONS LIKE Cl, F, NO3, SO4, ACETATE AND FORMATE INCREASING

14. IMPORTANT FINDINGS • ACIDITY OF RAINWATER, AEROSOLS & PARTICULATE MATTER INCREASING • NUMBER OF ACIDIC (pH <5.6) RAIN EVENTS INCREASING • NEUTRALIZING/ BUFFERING CAPACITY DECREASING • POLLUTANTS ARE MOSTLY OF CONTINENTAL ORIGIN • CORROSION OF MATERIALS ARE SIGNIFICANT

15. INDOFLUX – BASIC REQUIREMENTS • NETWORK SITES IN SOURCE/ SINK REGIONS • LONGTERM MEASURING EXPERIENCE & EXPERTISE • DISTINCTION BETWEEN NATURAL & ANTHROPOGENIC FLUXES THROUGH SOURCE APORTIONMENT • QA/QC & INTERCOMPARISON IN NET-WORK MODE

16. OBJECTIVES OF RRL STUDY • TO SET-UP A MICRO-MET TOWER WITH ALL SENSORS/REGULATORS AS PER INDOFLUX PROTOCOL AT THE EXISTING RURAL STATION OF BHUBANESWAR • TO ENGAGE GAS SENSORS FOR CONTINUOUS MONITORING OF TRACE COMPONENTS LIKE WATER VAPOR, CO2, NET ECO-SYSTEM EXCHANGE, BIOMASS ENTHALPY CHANGE AND METABOLIC HEAT STORAGE, TRACE GAS EMISSIONS FROM TERRESTRIAL SOURCES etc.

17. OBJECTIVES OF RRL STUDY-2 • TO CONTINUOUSLY MONITOR AEROSOL, DRY AND WET DEPOSITIONS • TO MONITOR CHANGES IN CHEMICAL COMPOSITION OF SOIL, PARTICULARLY NUTRIENT DEPLETION/AVAILABILITY • TO ANALYZE SAMPLES AND INTERPRET DATA • TO PARTICIPATE IN QA/QC EXERCISE
