Despite significant global and regional impacts, our understanding of specific gaseous fire emission factors (EFs) from tropical peat burning is limited to a handful of studies. Furthermore, there is substantial variability in EFs between sampled fires and/or studies. For example, methane EFs vary by 91% between studies. Here we present new fire EFs for the tropical peatland ecosystem; the first EFs measured for Malaysian peatlands, and only the second comprehensive study of EFs in this crucial environment. During August 2015 (under El Niño conditions) and July 2016, we embarked on field campaigns to measure gaseous emissions at multiple peatland fires burning on deforested land in Southeast Pahang (2015) and oil palm plantations in North Selangor (2016), Peninsula Malaysia. Gaseous emissions were measured using open-path Fourier transform infrared spectroscopy. The IR spectra were used to retrieve mole fractions of 12 different gases present within the smoke (including carbon dioxide and methane), and these measurements used to calculate EFs. Peat samples were taken at each burn site for physicochemical analysis and to explore possible relationships between specific physicochemical properties and fire EFs. Here we present the first evidence to indicate that substrate bulk density affects methane fire EFs reported here. This novel explanation of interplume, within-biome variability, should be considered by those undertaking greenhouse gas accounting and haze forecasting in this region and is of importance to peatland management, particularly with respect to artificial compaction. ©2018.

It seems that sunscreen use only at the beginning of the exposure or in a few cases a couple of times during exposure (at difference with the specific instructions sheets), was not sufficient to change significantly skin colorimetric parameters across participants. In conclusion UV personal doses on the ski-fields are often significantly higher than those on horizontal surfaces and consistently more intense respect to personal doses received by sunbathers on the beach in central Italy (ER range: 0.09g-0.42). Given the high levels of exposure observed in the present study, specific public health warnings with regards to the efficacy of sun-protection behaviours (proper application and re-application of sunscreen and protective measures such as hats and sun glasses) should be adopted.]]> Wed 09 Nov 2016 16:35:23 AEST ]]> Seasonal variability of secondary organic aerosol: A global modeling study Wed 09 May 2018 14:17:49 AEST ]]> Evaluation of Isoprene Photooxidation Using Smog Chamber Data and Chemical Mechanisms Wed 07 Sep 2016 15:02:01 AEST ]]> Climate velocity and the future global redistribution of marine biodiversity Tue 28 Jun 2016 10:32:54 AEST ]]> Seasonal rainfall totals of Australian stations can be modelled with distributions from the Tweedie family Tue 25 Aug 2015 14:19:37 AEST ]]> Calling phenology of a diverse amphibian assemblage in response to meteorological conditions Tue 22 May 2018 10:10:47 AEST ]]> Review of empirical methods for the calculation of the diurnal NO2 photolysis rate coefficient Tue 20 Feb 2018 13:52:38 AEST ]]> Stimulation of Secondary Organic Aerosol (SOA) produced from the photo-oxidation of isoprene by using the Master Chemical Mechanism (MCM v3.1) Tue 20 Feb 2018 12:03:26 AEST ]]> Are the anions MeO(CO) (n = 1 and 2) methoxide anion donors in the gas phase?

A degree-day factor for snowmelt is calculated using a linear relationship between combined measured melt and the number of degree-days. The slope of the regression line for these data points provides an estimate of the degree-day factor for use in runoff models. Average snowmelt is 17.8 mm d−1, but varies between 0 and 78 mm d−1. Melt occurs in a series of distinct cyclical events or pulses, each of which lasts 5-8 days. These correspond to the eastward passage of anticyclones, then troughs over the Southern Alps. When all days with northwest airflow across the Southern Alps are excluded, the melt factor is 3.4 mm °C−1 d−1. Northwest days belong to a different population with a much higher average melt factor of 9.1 mm °C−1 d−1, but more measurements are required to better understand key processes.]]> Mon 30 May 2016 11:55:29 AEST ]]> Cloud observations for the statistical evaluation of the UV index at Toowoomba, Australia Mon 27 Jun 2016 10:02:47 AEST ]]> Gas-phase intramolecular anion rearrangements of some trimethylsilyl-containing systems revisited.

Comparisons of output from both transport models with observations from satellite and ground-based platforms are presented at four times over a 36-hour period during the duststorms’ transit of mainland Australia. It is demonstrated that the performance of forecasts from both transport models in predicting the position of the dust front was quite good. However, it is shown that the forecasts are very sensitive to the land-surface specification that delineates potential source regions for the dust, and these data require further development before operational dust forecasting using these models could be relied upon.]]> Fri 07 Nov 2014 15:23:58 AEST ]]> A daily rainfall disaggregation model Fri 07 Nov 2014 13:35:30 AEST ]]> Climatic Variability and Climate Change: Scenarios and Projections.
