项目摘要
Biomass burning aerosol (BBA) exerts a considerable impact on regional radiation budgets as it significantly perturbs the surface fluxes and atmospheric heating rates and its cloud nucleating (CCN) properties perturb cloud microphysics and hence affect cloud radiative properties, precipitation and cloud lifetime. It is likely that such large influences on heating rates and CCN will affect regional weather predictions in addition to climatic changes. It is increasingly recognised that biomass burning affects the biosphere but the magnitude of the effects need to quantified. However, BBA is a complex and poorly understood aerosol species because of the mixing of the black carbon with organic and inorganic species. Furthermore, emission rates are poorly quantified and difficult to represent in models. It is now timely to address these challenges as both measurement methods and model capabilities have developed rapidly over the last few years and are now sufficiently advanced that the processes and properties of BBA can be sufficiently constrained by measurements; these can be used to challenge the new aerosol schemes used in numerical weather prediction (NWP) and climate models. Amazonia is one of the most important biomass burning regions in the world, being significantly impacted by intense biomass burning during the dry season leading to highly turbid conditions, and is therefore a key environment for quantifying these processes and determining the influence of these interactions on the weather and climate of the region. Though previous large scale studies of BBA over Amazonia and its radiative impacts have been performed, these are now over a decade old and considerable scientific progress can be made towards addressing all of the above questions given the rapid advance of models and measurements in recent years. We are therefore proposing a major consortium programme, SAMBBA, a consortium of 7 university partners and the UK Met Office, which will deliver a suite of ground, aircraft and satellite measurements of Amazonian BBA and use this data to 1) improve our knowledge of BB emissions; 2) challenge and improve the latest aerosol process models; 3) challenge and improve satellite retrievals; 4) test predictions of aerosol influences on regional climate and weather over Amazonia and the surrounding regions made using the next generation of climate and NWP models with extensive prognostic aerosol schemes; and 5) assess the impact of .biomass burning on the Amazonian biosphere.The main field experiment will take place during September 2012 and is based in Porto Velho, Brazil. At this time of year, widespread burning takes place across the region leading to highly turbid conditions. The UK large research aircraft (FAAM) will be used to sample aerosol chemical, physical and optical properties and gas phase precursor concentrations. Measurements of radiation will also be made using advanced radiometers on board the aircraft and satellite data will also be utilised. The influences of biomass burning aerosols are highly significant at local, weather, seasonal, and climate temporal scales necessitating the use of a hierarchy of models to establish and test key processes and quantify impacts. We will challenge models carrying detailed process descriptions of biomass burning aerosols with the new, comprehensive observations being made during SAMBBA to evaluate model performance and to improve parameterisations. Numerical Weather Prediction and Climate model simulations with a range of complexity and spatial resolution will be used to investigate the ways in which absorbing aerosol may influence dynamics and climate on regional and wider scales. At the heart of the approach is the use of a new range of models that can investigate such interactions using coupled descriptions of aerosols and clouds to fully investigate feedbacks at spatial scales that are sufficiently well resolved to assess such processes.
生物质燃烧气溶胶(BBA)对区域辐射收支产生显著影响,它显著扰动地面通量和大气加热率,其云成核(CCN)特性扰动云微物理,从而影响云辐射特性、降水和云寿命。除了气候变化之外,对加热率和云凝结核的如此大的影响很可能会影响区域天气预报。人们越来越认识到生物质燃烧会影响生物圈,但影响的程度需要量化。然而,BBA是一个复杂的和知之甚少的气溶胶物种,因为黑碳与有机和无机物种的混合。此外,排放率的量化很差,难以在模型中表示。现在正是解决这些挑战的时候,因为测量方法和模式能力在过去几年中发展迅速,现在已经足够先进,BBA的过程和属性可以通过测量充分约束;这些可以用来挑战数值天气预报(NWP)和气候模式中使用的新气溶胶方案。亚马逊河流域是世界上最重要的生物质燃烧地区之一,在旱季受到强烈生物质燃烧的严重影响,导致高度浑浊的条件,因此是量化这些过程和确定这些相互作用对该地区天气和气候影响的关键环境。虽然以前的大规模研究BBA在亚马逊河流域及其辐射的影响已经进行,这些现在已经超过十年的历史,相当大的科学进步,可以解决所有上述问题的模型和测量在最近几年的快速发展。因此,我们提出了一个主要的联盟计划,SAMBBA,一个由7所大学合作伙伴和英国气象局组成的联盟,它将提供一套亚马逊BBA的地面,飞机和卫星测量数据,并使用这些数据来1)提高我们对BB排放的认识; 2)挑战和改进最新的气溶胶过程模型; 3)挑战和改进卫星检索; 4)使用下一代气候和数值预报模式以及广泛的气溶胶预报方案,测试气溶胶对亚马逊河流域及其周边地区区域气候和天气的影响;和5)评估生物质燃烧对亚马逊生物圈的影响。主要的实地实验将于2012年9月在韦略港进行,巴西每年的这个时候,整个地区都会发生大范围的燃烧,导致高度浑浊的状况。联合王国大型研究飞机(FAAM)将用于对气溶胶的化学、物理和光学特性以及气相前体浓度进行采样。还将使用飞机上的先进辐射计进行辐射测量,还将利用卫星数据。生物质燃烧气溶胶的影响在当地,天气,季节和气候时间尺度上非常显着,需要使用一系列模型来建立和测试关键过程并量化影响。我们将挑战模型进行详细的过程描述的生物质燃烧气溶胶与新的,全面的观察正在SAMBBA期间,以评估模型的性能和改进参数化。将使用具有一系列复杂性和空间分辨率的数值天气预报和气候模式模拟来研究吸收性气溶胶可能影响区域和更大尺度上的动力学和气候的方式。该方法的核心是使用一系列新的模型,这些模型可以使用气溶胶和云的耦合描述来研究这种相互作用,以充分研究空间尺度上的反馈,这些空间尺度足以很好地解决评估这种过程。
