There are currently several research projects and operational programs underway relevant to IBBI. These include several major large field campaigns in US led by NOAA, NASA, NSF, The Joint Science Fire Program, and DOE, a NCAR ACCORD synthesis effort, and a growing international constellation of satellites providing information on global fire activity required to integrate emissions and the atmospheric impact of fires. IBBI wishes to capitalize on these research projects and operational programs. In 2017, IBBI held its 4th workshop 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.
