The MISR Research Product Algorithm – producing global, self-consistent, pixel-level aerosol retrievals for the Multi-angle Imaging SpectroRadiometer

Abstract. The MISR Research Aerosol retrieval algorithm (RA) was developed in parallel with the MISR standard operational algorithm (SA), to explore innovative retrieval ideas for possible implementation in the SA, and to provide higher-spatial-resolution results with enhanced se...

Observation-constrained clear-sky direct radiative forcing of black carbon containing aerosols reveals distinct radiative regimes across urban Asia

Black carbon (BC) aerosols exert a strong yet uncertain influence on the atmospheric energy balance, yet their radiative forcing estimates remain poorly constrained. Current top-down and bottom-up approaches remain limited in resolving how microphysical evolution and column prope...
