We present a six-year global climatology of cloud properties, obtained from observations of the Atmospheric Infrared Sounder (AIRS) onboard the NASA Aqua satellite. Cloud-Aerosol Lidar and Infrared Pa...
Climate change assessment for Mediterranean agricultural areas by statistical downscaling
Climate change assessment Mediterranean agricultural areas statistical downscaling
2010/10/21
In this paper we produce projections of seasonal precipitation for four Mediterranean areas: Apulia region (Italy), Ebro river basin (Spain), Po valley (Italy) and Antalya province (Turkey). We perfor...
Cirrus clouds in a global climate model with a statistical cirrus cloud scheme
Cirrus clouds a global climate model a statistical cirrus cloud scheme
2010/8/13
A statistical cirrus cloud scheme that accounts for mesoscale temperature perturbations is implemented in a coupled aerosol and atmospheric circulation model to better represent both subgrid-scale sup...
Statistical properties of aerosol-cloud-precipitation interactions in South America
Statistical properties aerosol-cloud-precipitation interactions South America
2010/3/16
Given the complex interaction between aerosol, cloud, and atmospheric properties, it is difficult to extract their individual effects to observed rainfall amount. This research uses principle componen...
Source identification of short-lived air pollutants in the Arctic using statistical analysis of measurement data and particle dispersion model output
short-lived air pollutants Arctic using statistical analysis particle dispersion model output
2010/2/1
As a part of the IPY project POLARCAT (Polar Study using Aircraft, Remote Sensing, Surface Measurements and Models, of Climate Chemistry, Aerosols and Transport), this paper studies the sources of equ...
A few prospective ideas on climate reconstruction：from a statistical single proxy approach towards a multi-proxy and dynamical approach
climate reconstruction dynamical approach multi-proxy
2009/12/3
Important progresses have been made in palaeoclimatological studies by using statistical methods. But they are in somewhere limited as they take the present as an absolute reference. This is particula...
A statistical analysis of the influence of deep convection on water vapor variability in the tropical upper troposphere
deep convection water vapor variability tropical upper troposphere
2009/8/18
The factors that control the influence of deep convective detrainment on water vapor in the tropical upper troposphere are examined using observations from multiple satellites in conjunction with a tr...
Statistical analysis of anthropogenic non-methane VOC variability at a European background location（Jungfraujoch, Switzerland）
anthropogenic non-methane VOC European background location Jungfraujoch Switzerland
2009/6/2
In-situ measurements of 7 volatile hydrocarbons, CxHy, and 3 chlorinated organic compounds, CxHyClz, were performed at Jungfraujoch (Switzerland) during eight years (2000–2007). The analysis of 4-h re...
Statistical properties of cloud lifecycles in cloud-resolving models
Statistical properties cloud lifecycles cloud-resolving models
2009/3/31
A new technique is described for the analysis of cloud-resolving model simulations, which allows one to investigate the statistics of the lifecycles of cumulus clouds. Clouds are tracked from timestep...
Long term measurements of submicrometer urban aerosols: statistical analysis for correlations with meteorological conditions and trace gases
