two new programs are presently being linked within GEIA: ECCAD and CIERA. Their common aim is to facilitate access to emissions information. ECCAD (Emissions of chemical Compounds & Compilation of Ancillary Data, http://ether.ipsl. jussieu.fr/eccad) GEIA's new interactive emissions data portal that provides consistent access to global and regional emissions inventories and ancillary data, along with easy-to-use tools for analysis and visualization. CIERA (Community Initiative for Emissions Research & Applications, http://ciera-air.org/) is a GEIA community effort to develop interoperability in emissions datasets and tools, support evaluations of emissions inventories, and connect the emissions development and user communities. More details about ECCAD and CIERA are presented in the articles immediately following this note.
