IGAC S MISSION IS TO FACILITATE ATMOSPHERIC CHEMISTRY RESEARCH TOWARDS A SUSTAINABLE WORLD. THIS IS ACHIEVED THROUGH IGAC S THREE FOCAL AREAS: FOSTERING COMMUNITY BUILDING CAPACITY AND PROVIDING LEADERSHIP. IGAC S MISSION IS IN LARGE PART IMPLEMENTED BY IT SPONSORED ACTIVITIES THAT ADDRESS AN AREA OF ATMOSPHERIC CHEMISTRY RESEARCH THAT REQUIRES COORDINATION ACROSS GEOGRAPHICAL BOUNDARIES AND/OR DISCIPLINES INITIATES NEW INQUIRY AND/OR FILLS A SCIENTIFIC NEED WITHIN THE COMMUNITY AND ADDRESSES ONE OR MORE OF IGAC S FOCAL AREAS. A KEY COMPONENT OF IGAC ACTIVITIES IS REGULAR WORKSHOPS THAT BRING TOGETHER SCIENTISTS FROM AROUND THE WORLD TO DISSEMINATE SCIENTIFIC INFORMATION FOSTER COMMUNITY AND PROVIDE LEADERSHIP TO THE WIDER INTERNATIONAL ATMOSPHERIC ON RESEARCH PRIORITIES AND INTERNATIONAL COLLABORATIONS. THE INTERDISCIPLINARY BIOMASS BURNING INITIATIVE (IBBI) IS AN IGAC ACTIVITY THAT IS JOINTLY SPONSORED BY THE INTEGRATED LAND- ATMOSPHERE PROCESSES STUDY (ILEAPS) AND THE WORLD METEOROLOGICAL ORGANIZATION (WMO). THE PRIMARY GOAL OF IBBI IS TO IMPROVE SCIENTIFIC UNDERSTANDING OF THE VARIOUS PROCESSES ASSOCIATED WITH OPEN BIOMASS BURNING IN ORDER TO MAKE ATMOSPHERIC COMPOSITION PREDICTION AND AIR QUALITY MONITORING AND FORECASTING BETTER. IBBI WISHES TO CAPITALIZE ON SEVERAL CURRENT RESEARCH PROJECTS AND OPERATIONAL PROGRAMS LISTED BELOW BY HOLDING A WORKSHOP 10-12 JULY 2017 AT THE UNIVERSITY OF COLORADO BOULDER CO USA TO BRING TOGETHER THE INTERNATIONAL BIOMASS BURNING RESEARCH COMMUNITY WITH THE ULTIMATE GOAL OF DISCUSSING HOW TO LEVERAGE THESE EFFORTS IN THE U.S. AND EUROPE TO IMPROVE SCIENTIFIC RESEARCH AND UNDERSTANDING OF OPEN BIOMASS BURNING AROUND THE WORLD SPECIFICALLY FOCUSING ON IBBI KEY TOPICS 1-4.
