Cloud base height estimation from viirs

Webparticularly cloud-base height (mostly referred to as ‘‘cloud ceiling’’ whenreferring tothe cloudlayer closest to the surface), is a key parameter for the aviation community (Vislocky and Fritsch 1997; Forsythe et al. 2000; Hansen 2007; Marzban et al. 2007; Miller et al. 2014). Knowledge of the cloud-base height (CBH) with WebVIIRS imager pixels (750m at nadir), and adopted the ice cloud top height retrieval from the sounder as the a priori value to improve the imager-based cloud height retrieval us-ing an optimal estimation approach. Here, we denote FOV for the sounder and pixel for the imager exclusively to mini-mize confusion between the two sensors. This method ...
