Increasing atmospheric carbon dioxide (CO2) is the principal driver of anthropogenic climate change. Asia is an important region for the global carbon budget, with 4 of the world's 10 largest national emitters of CO2. Using an ensemble of seven atmospheric inverse systems, we estimated land biosphere fluxes (natural, land-use change and fires) based on atmospheric observations of CO2 concentrat...

The Cone Calorimeter—ISO 5660 and ASTM E1354—has been the primary bench-scale test for measuring heat release rate fires ever since early 1990s. technical details of how to construct operate instrument has well documented in standards, reports, published papers. But background its development had not earlier published. Because Calorimeter represented a ground-breaking, new approach studies, pre...
