Project

"New cloud products from (A)ATSR(2) by fusing stereo photogrammetry and Optimal Estimation for improving the detection of global climate change from the monitoring of changing cloud-top height distributions after validation using ground-based radar, lidar and imaging."

Supervisors: Prof. Jan-Peter Muller & Dr Caroline Poulsen

Studies of the vertical and horizontal distributions of clouds over a 15 year time period starting in 1997 will be made using products derived from the unique multispectral and multi -look stereo capabilities of the British (A)ATSR(2) instrument. These satellite-derived products will be inter- compared where temporal overlap exists and with other ESA (MERIS) and NASA (MISR and MODIS cloud products) to assess what unique information each product provides and how by combining this unique information, insights into the nature of clouds and their responses to changing levels of CO2 can be better assessed. These satellite-derived products will also be compared against cloud boundary and microphysical information derived from ground-based radars and lidars at the Chilbolton Facility for Atmospheric Radar Research (CFARR) as well as the ARM sites in the central US and in the tropical West Pacific have when comparing continuous profile measurements against 2D first-observable and Australia. This will allow us to assess how representative these sites are of general cloud climatologies as well as what impact time and space sampling characteristics surface ones from satellite.
