1. Retrieval of Cloud Top Pressure
University essay from Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Tekniska fakultetenAbstract : In this thesis the predictive models the multilayer perceptron and random forest are evaluated to predict cloud top pressure. The dataset used in this thesis contains brightness temperatures, reflectances and other useful variables to determine the cloud top pressure from the Advanced Very High Resolution Radiometer (AVHRR) instrument on the two satellites NOAA-17 and NOAA-18 during the time period 2006-2009.
