Abstract. The VOCALS-REx field campaign which took place in 2008 used several platforms to investigate the persistent marine stratocumulus cloud deck off the Chilean and Peruvian coasts. VOCALS-UK was the UK component of the experiment, during which the FAAM BAe-146 aircraft gathered data in the stratocumulus cloud. It flew 13 research flights including investigations along 20° S transects.

In this paper, the shortwave cloud albedo derived from the Cloud Droplet Probe is compared with the albedo measured from two shortwave radiometers. Four clean cloud segments were selected for investigation. The suitability of the δ-Eddington approximation as a method of calculating shortwave albedo is investigated and it is found to be acceptable (with a R2 of 0.78) for solar zenith angles below 65 degrees.
