Description: Das Projekt "FP4-ENV 2C, CLOUDMAP: Cirrus and Contrail Cloud-Top-Maps from Satellites for Weather Forecasting and Climate Change Analysis" wird/wurde gefördert durch: Bundesamt für Bildung und Wissenschaft / Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich (ETH), Institut für Geodäsie und Photogrammetrie.Overall Objectives To provide cloud-top parameters (heights, amounts, types, wind-fields) to Weather Forecasters and Global Climate Modellers to improve their ability to improve forecasts and quantify the impact of natural and anthropogenic changes to the environment. A major European meteorological institute will evaluate the accuracy and utility of these products including conducting a user market survey of their potential for European meteorological research and operational use. Another major meteorological research centre will quantitatively evaluate the utility of these new cloud-top parameters to enbance our understanding of the effects of sub-sonic contrail clouds on the climate including a comparison of parameters against existing spatial frequency maps derived from manual interpretation of AVHRR data. Three different methods of measuring cloud-top parameters will be assessed: stereoscopic observations, forbidden Oxygen and lidar. Validation of these parameters will be catried out using ground-based wide-field stereo imagers as well as ground-based millimetre radar and ceilometers. Proposal Content CLOUDMAP will focus on the establishment and demonstration of new data-sets from existing and new sensors which will be of great utility for climate change analysis. In particular, it is well known that current estimates of Cirrus clouds measured using low resolution meteorological sensors do not properly take into account the fine detail and broken nature of Cirrus clouds. It is therefore a key objective of this proposal to produce cloud-top parameters to try to understand whether current estimates are erroneous and by how much. Anthropogenic changes affect the upper atmosphere principally through contrails formed from sub-sonic jet aircraft at middle to high latitudes. Prime Contractor: University College London, Department of Photogrammetry and Surveying; London/UK.
