Abstract: Infrared heating rate calculations with the emissivity formulation are improved by developing simple methods to minimize the effects of the two main sources of error 1) the use of the strong-line approximation; 2) the ...

Abstract: A retrieval technique based on cloud classification is designed to derive humidity profiles from Meteosat visible (VIS), infrared window (IR), and water vapor (WV) channels, or equivalent sensors available on other satellites. ...

Abstract: Two methods of deriving probability of precipitation fields (PP) over oceanic areas are presented and compared. The cloud fields are analyzed at the scale of ?130?150 km from satellite visible and infrared imagery and ...

Abstract: A scheme is presented for the automated classification of oceanic cloud patterns. The 20 cloud classes reflect the rich variety of morphologies that are detectable from space. A training set is defined by 2000 samples of ...

Abstract: Both the issues of high-resolution satellite analysis and model evaluation for a region centered on the Arctic Circle (60°?75°N) are addressed. Model cloud fraction, cloud height, and outgoing radiation are compared to ...

Abstract: Both the issues of high-resolution satellite analysis and model evaluation for a region centered on the Arctic Circle (60°?75°N) are addressed. Model cloud fraction, cloud height, and outgoing radiation are compared to ...

Abstract: This study explores the feasibility of performing an objective analysis of instantaneous rain rate combining satellite estimates (and eventually other types of observations) with those from a numerical prediction model ...

Abstract: A strong linearity exists between the 6.7-?m clear-sky outgoing brightness temperature (BT) and dewpoint depression (DPD) at upper-tropospheric levels. A similar relationship, using the logarithm of relative humidity instead ...

Abstract: A structural-stochastic image model is developed for the analysis and synthesis of cloud images. The ability of the model to characterize the visual appearance of cloud fields observed by satellite with a limited number ...

Abstract: here has been a significant increase of interest in the building of a comprehensive Arctic observing system in recent years to properly and timely track the environmental and climate processes in this vast region. In this ...
