Inventories of emissions of pollutants to air form the basis for model predictions of air quality, visibility, human exposure, human health impacts, and climate change. They are further required to understand relationships between individual source locations or source types and targets. None of the model predictions and analyses can be better than the emission database on which they are founded. This project seeks to greatly improve the emissions inventory for the wider Delhi area, one of the most polluted conurbations globally. The emission inventory will be compiled at a 1 km x 1 km resolution with diurnal and seasonal temporal profiles. It will cover NOx, SOx, NH3, total volatile compounds with breakdown into its chemical profile, particulate matter in fine (PM2.5) and coarse (PM10) size ranges, together with the toxic metal components within, as well as CO2 and CO as combustion tracers. To improve the emission inventory we will make laboratory-based measurements of emission factors and also measure, for the first time in India, the emissions from individual vehicles under real-world driving conditions to characterize the actual Delhi vehicle fleet. We will further perform the first micrometeorological flux measurements of these compounds above the city and study their enrichment along a transect. This will provide further information on potentially missing sources and serve as a direct assessment of the quality of the emissions inventory. We will further apply a state-of-the-art chemistry and transport model to infer the concentrations that would be expected on the basis of the new emissions inventory for comparison against concentration data from air quality networks and the wider NERC-MRC-MoES-DBT programme.ODA compliance:By providing the emissions data required to assess human exposure and develop cost-effective solutions to combat air pollution in Delhi, the project will target poverty and development issues. Accurate knowledge of emissions is a key factor underpinning the development of mitigation strategies which will deliver improved public health, whilst further allowing economic growth. Both the UK and Indian research teams will benefit from their interaction and exploitation of complementary expertise. The project will leave a legacy beyond the project lifetime by increasing the research capacity of the Indian teams and providing the knowledge base which will allow the findings to be extrapolated to the rest of India. Thus, the project findings will continue to contributing to the improvement of life and welfare of more than a billion people.

污染物排放到空气中的清单构成了空气质量、能见度、人类暴露、人类健康影响和气候变化模型预测的基础。他们还需要了解各个来源位置或来源类型与目标之间的关系。没有一个模型的预测和分析能比它们所依据的排放数据库更好。该项目旨在极大地改善德里地区的排放清单，德里地区是全球污染最严重的城市之一。排放清单将以1公里×1公里的分辨率编制，并附有日和季节的时间分布。它将涵盖NOx、SOx、NH3、总挥发性化合物及其化学分布，细(PM2.5)和粗(PM10)颗粒物，以及其中的有毒金属成分，以及作为燃烧示踪剂的二氧化碳和一氧化碳。为了改善排放清单，我们将对排放系数进行实验室测量，并首次在印度测量真实世界驾驶条件下单个车辆的排放量，以表征实际的德里车队。我们将进一步进行城市上空这些化合物的首次微气象通量测量，并研究它们在样带上的丰度。这将提供关于潜在遗失源的进一步信息，并作为对排放清单质量的直接评估。我们将进一步应用最先进的化学和交通模型，根据新的排放清单推断预期的浓度，以便与空气质量网络和更广泛的NERC-MRC-MOES-DBT方案的浓度数据进行比较。官方发展援助遵从性：通过提供评估人类接触所需的排放数据，并制定具有成本效益的解决方案来防治德里的空气污染，该项目将针对贫困和发展问题。对排放的准确了解是制定缓解战略的关键因素，这些战略将改善公众健康，同时进一步促进经济增长。英国和印度的研究团队都将从他们的互动和利用互补的专业知识中受益。该项目将通过增加印度团队的研究能力并提供知识基础，使研究结果能够外推到印度其他地区，从而在项目生命周期之后留下遗产。因此，项目成果将继续为改善十多亿人的生活和福利作出贡献。
