Aerosol-cloud interaction inferred from MODIS satellite data and global aerosol models [PDF]

open access: yesAtmospheric Chemistry and Physics, 2007
We have used the MODIS satellite data and two global aerosol models to investigate the relationships between aerosol optical depth (AOD) and cloud parameters that may be affected by the aerosol concentration. The relationships that are studied are mainly

Forest cover estimation in Ireland using radar remote sensing: a comparative analysis of forest cover assessment methodologies [PDF]

open access: yes, 2015
Quantification of spatial and temporal changes in forest cover is an essential component of forest monitoring programs. Due to its cloud free capability, Synthetic Aperture Radar (SAR) is an ideal source of information on forest dynamics in countries ...

Comparing methods to estimate cloud cover over the Baikal Natural Territory in December 2020

open access: yesSolar-Terrestrial Physics, 2022
The paper addresses the issue of how much cloud cover data obtained using satellite and model-interpolation techniques are suitable for monitoring the transparency of the atmosphere and determining conditions for airglow observations at a local ...

Cloud Cover Diurnal Cycles in Satellite Data and Regional Climate Model Simulations

open access: yesMeteorologische Zeitschrift, 2012
The amount and diurnal cycle of cloud cover play an important role in the energy and water cycle of the earth-atmosphere system and influence the radiation budget of the earth. Due to its importance and the challenging nature of its quantification, cloud

Testing the proposed link between cosmic rays and cloud cover

open access: yes, 2008
A decrease in the globally averaged low level cloud cover, deduced from the ISCCP infra red data, as the cosmic ray intensity decreased during the solar cycle 22 was observed by two groups.

Granger causality of the local Hadley cell and large-scale cloud cover over South Africa

open access: yesSouth African Journal of Science, 2019
This study demonstrates that Hadley cell dynamics could be used as a proxy to determine cloud cover and thus solar energy potential over South Africa. Granger causality was used to investigate causal interactions between the Hadley cell and cloud cover ...

Analysis of temporal and spatial variations of Cloud cover using remote sensing data at Iran [PDF]

open access: yesمخاطرات محیط طبیعی, 2018
The aim of this research is an analysis of tempo-spatial variations of Cloud cover at Iran. To achieve the goal, Cloud Fraction parameter has been used from cloud product of MODIS sensor on Terra satellite at level 2 and version 6 (MOD06) in the period ...

Multidecadal changes in near‐global cloud cover and estimated cloud cover radiative forcing [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2005
This study examines variability in zonal mean surface‐observed upper‐level (combined midlevel and high‐level) and low‐level cloud cover over land during 1971–1996 and over ocean during 1952–1997. These data were averaged from individual synoptic reports in the Extended Edited Cloud Report Archive (EECRA).
