2010/8/13
The Global Retrieval of ATSR Cloud Parameters and Evaluation (GRAPE) project has produced a global data-set of cloud and aerosol properties from the Along Track Scanning Radiometer-2 (ATSR-2) instrume...
Insights into secondary organic aerosol formed via aqueous-phase reactions of phenolic compounds based on high resolution mass spectrometry
secondary organic aerosol aqueous-phase reactions phenolic compounds high resolution mass spectrometry
2010/8/13
Recent work has shown that aqueous-phase reactions of phenolic compounds – phenol (C6H6O), guaiacol (C7H8O2), and syringol (C8H10O3) – can form secondary organic aerosol (SOA) at high yields. Here we ...
High resolution cyclostratigraphy of the early Eocene–new insights into the origin of the Cenozoic cooling trend
