Climatic effects of 1950-2050 changes in US anthropogenic aerosols-Part 1: Aerosol trends and radiative forcing

We calculate decadal aerosol direct and indirect (warm cloud) radiative forcings from US anthropogenic sources over the 1950-2050 period. Past and future aerosol distributions are constructed using GEOS-Chem and historical emission inventories and future p ...

Hydroclimatology of dual-peak annual cholera incidence: Insights from a spatially explicit model

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Lorenzo Righetto, Marino Gatto

Cholera incidence in some regions of the Indian subcontinent may exhibit two annual peaks although the main environmental drivers that have been linked to the disease (e.g., sea surface temperature, zooplankton abundance, river discharge) peak once per yea ...

Evaluating Error Propagation in Coupled Land-Atmosphere Models

Dasaraden Mauree

This study examines how land-use errors from the Land Transformation Model (LTM) propagate through to climate as simulated by the Regional Atmospheric Model System (RAMS). The authors conducted five simulations of regional climate over East Africa: one usi ...

Abrupt rise in atmospheric CO2 at the onset of the Boølling/ Alleroød: In-situ ice core data versus true atmospheric signals

Jérôme Chappellaz

During the last glacial/interglacial transition the Earth's climate underwent abrupt changes around 14.6 kyr ago. Temperature proxies from ice cores revealed the onset of the Boølling/Alleroød (B/A) warm period in the north and the start of the Antarctic C ...

Hydrologic response of an alpine watershed: Application of a meteorological wireless sensor network to understand streamflow generation

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau, Marc Diebold, François Ingelrest, Simone Padoan, Silvia Simoni

A field measurement campaign was conducted from June to October 2009 in a 20 km2 catchment of the Swiss Alps with a wireless network of 12 weather stations and river discharge monitoring. The objective was to investigate the spatial variability of meteorol ...

On the suitability of partially clathrated ice for analysis of concentration and δ13C of palaeo-atmospheric CO2

Jérôme Chappellaz

The description of rapid climatic changes during the last glacial period at high northern latitudes has been largely documented through Greenland ice cores that are unique climatic and environmental records. However, Greenland ice isotopic records are bias ...

2500 Years of European Climate Variability and Human Susceptibility

Jed Oliver Kaplan

Climate variations influenced the agricultural productivity, health risk, and conflict level of preindustrial societies. Discrimination between environmental and anthropogenic impacts on past civilizations, however, remains difficult because of the paucity ...

Magnitude and seasonality of wetland methane emissions from the Hudson Bay Lowlands (Canada)

Jed Oliver Kaplan, Isabelle Bey, Jérôme Drevet

The Hudson Bay Lowlands (HBL) is the second largest boreal wetland ecosystem in the world and an important natural source of global atmospheric methane. We quantify the HBL methane emissions by using the GEOS-Chem chemical transport model to simulate aircr ...

Seasonal trends and temperature dependence of the snowfall/precipitation-day ratio in Switzerland

Martine Rebetez, Gaëlle Serquet

This paper analyzes the proportion of snowfall days relative to precipitation days, in order to assess the impact of changing temperatures on snowfall, while minimizing the impact of variations in precipitation frequency and intensity. We analyzed the rati ...

Thermal Circulation Patterns and Turbulent Fluxes along Steep Mountain Slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau, Fabian Bärenbold

In hydrology, it is crucial to understand the atmospheric flow dynamics in mountainous terrain to predict turbulent exchanges of heat and moisture accurately at the regional scale. Under clear skies and weak synoptic conditions, these land–atmosphere inter ...
