Regional statement on the impacts of the 2015/16 El Niño and 2016/17 climate and tropical cyclone outlook for the Pacific Islands
The Pacific Island Climate Outlook Forum (PICOF) has issued its Regional climate outlook and tropical cyclone outlook for 2016/2017. The forum, which took place on 17th and 18th of October in Nadi, Fiji,

Comparing multiple model-derived aerosol optical properties to collocated ground-based and satellite measurements
<p>Anthropogenic aerosols are a key factor governing Earth’s climate, and play a central role in human-caused climate change. However, because of aerosols’ complex physical, optical, and dynamical

Estimating the effect of air pollution on road safety using atmospheric temperature inversions
This paper estimates the causal eff ect of increased ambient air pollution on the frequency of road traffic accidents in the United Kingdom between 2009 and 2014. An instrumental variable approach is applied,

The spatially varying influence of humans on fire probability in North America
<p>Humans affect fire regimes by providing ignition sources in some cases, suppressing wildfires in others, and altering natural vegetation in ways that may either promote or limit fire. In North America,

Decadal variability of tropical tropopause temperature and its relationship to the Pacific Decadal Oscillation
<p>Tropopause temperatures (TPTs) control the amount of stratospheric water vapour, which influences chemistry, radiation and circulation in the stratosphere, and is also an important driver of surface

Effects of sample size on estimation of rainfall extremes at high temperatures
<p>High precipitation quantiles tend to rise with air temperature, following the so-called Clausius–Clapeyron scaling. This CC-scaling relation breaks down, or even reverts, for very high temperatures.

Ion-induced nucleation of pure biogenic particles
<p>Atmospheric aerosols and their effect on clouds are thought to be important for anthropogenic radiative forcing of the climate, yet remain poorly understood. Globally, around half of cloud condensation

Urban heat island impacts on plant phenology: intra-urban variability and response to land cover
<p>Despite documented intra-urban heterogeneity in the urban heat island (UHI) effect, little is known about spatial or temporal variability in plant response to the UHI. Using an automated temperature
