The background is a true color image of the clouds at 250 m resolution, with an iridescent overlay showing a 1km resolution cloud droplet number (Nd) retrieval for the same overpass. Red, green and blue colors show high (~1000 #\/cm3), medium (~100 #\/cm3) and low (~10 #\/cm3) Nd values. The east to west Nd gradient is produced mainly by anthropogenic aerosols, which influence cloud properties. We have shown that applying these retrievals in a data assimilation framework can help improve model estimates of below-cloud aerosol, allowing the observing system to \u201csee aerosols\u201d even under cloudy conditions.
