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

IMPORTANT FINDINGS GHG emission from rice and pulse cultivation Rice Methane E SIF3.3gm/m 2 Rainy season 1.97gm/m 2 Kharif season NO2 0.01 mgm/m 2 7.11 mgm/m 2 Pulses 3.38-4.1 NO2
12
IMPORTANT FINDINGS Factors affecting 1.Soil temperature 2.Fertiliser addition 3.Soil redox potential 4.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, CO 2, 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
