متن کاملMultiple satellite observations of cloud cover in extratropical cyclones
[1] Using cloud observations from NASA Moderate Resolution Imaging Spectroradiometer, Multiangle Imaging Spectroradiometer, and CloudSat-CALIPSO, composites of cloud fraction in southern and northern hemisphere extratropical cyclones are obtained for cold and warm seasons between 2006 and 2010, to assess differences between these three data sets, and between summer and winter cyclones. In both ...

Article history: Received 27 April 2011 Received in revised form 10 January 2012 Accepted 10 January 2012 Available online xxxx Global and zonal monthly means of cloud cover fraction for total cloudiness (CF) from the ISCCP D2 dataset are compared to same quantities produced by the 20th century simulations of 21 climatemodels from theWorld Climate Research Programme's (WCRP's) CoupledModel Inte...
متن کاملSpatiotemporal Variations of Total Cloud Cover and Cloud Optical Thickness in Iran
A knowledge of cloud properties and spatiotemporal variations of clouds is especially crucial to understand the radiative forcing of climate. This research aims to study cloudiness in Iran using the most recent satellite data, powerful databases, and regional and seasonal analyses. In this study, three data series were used for the spatiotemporal variations of cloudiness in the country: A) Clou...
متن کاملShort-term variability in satellite-derived cloud cover and galactic cosmic rays: An update
Previous work by Todd and Kniveton (2001) (TK2001) has indicated a statistically significant association (at the daily timescale) between short-term reductions in galactic cosmic rays, specifically Forbush decrease (FD) events, and reduced cloud cover, mainly over Antarctica (as recorded in International Satellite Cloud Climatology Project (ISCCP) D1 data). This study presents an extension of t...
