“…The emissions due to various sectors used in the model for 2001 are taken similar to the work by Beig and Brasseur [2006]. Over the Indian subcontinent, high-resolution emission estimates from the Indian national inventory [Dalvi et al, 2006] have been used which account for the rapid temporal and smallscale geographical variability. It considers discrete mixture of modern urban population and traditional rural and agro-dominated population with diverse socio-economic differences.…”

We investigate the special behavior in the distribution of boundary layer ozone and its precursors over world's most extensive tract of uninterrupted alluvium and intensively farmed zones situated in the foothills of Himalayas as major river basin, known as Indo‐Gangetic Plains (IGP). The study makes use of a Chemistry‐Transport Model forced with dynamical fields and new emission inventories of pollutants established for 2001. It is found that the IGP region is highly vulnerable to human induced pollutant emissions due to conducive synoptic weather pattern which make it a source regions of ozone precursors within which these tracers remain confined and reinforce photochemical production of ozone. In addition, the continental tropical convergence zone and long range transport play a vital role. As a result, elevated levels of ozone concentration (maximum up to 80 ppbv) and its precursors with cellular structure of spatial variation with large seasonality are noticed.

“…Notably, the emissions of pollutants which are poorly documented especially for the South Asian region play an important role in the distribution of these tracers. Recently, emission inventory of these pollutants are made available with finer resolution [Dalvi et al, 2006] which is used in the present work.…”

“…Furthermore, this region is densely populated, hence anthropogenic activities are also high: CO 2 emissions from transport, coal and wood burning for domestic cooking, ecosystem mass burning are common throughout the year (Garg et al, 2001). In addition to this, there are LPSs densely clustered near Delhi, along the eastern coal belt, and uniformly spread around the rest of the IG region (Garg et al, 2002;Dalvi et al, 2006, Ghude et al, 2008. Since power plants are the largest CO 2 emitters (DoE and EPA, 2000), it is interesting to observe the CO 2 hot spots and location of power plants simultaneously.…”

Abstract. In this paper we examine CO 2 emission hot spots and sink regions over India as identified from global model simulations during the period 2000-2009. CO 2 emission hot spots overlap with locations of densely clustered thermal power plants, coal mines and other industrial and urban centres; CO 2 sink regions coincide with the locations of dense forest. Fossil fuel CO 2 emissions are compared with two bottom-up inventories: the Regional Emission inventories in ASia (REAS v1.11;2000 and the Emission Database for Global Atmospheric Research (EDGAR v4.2) (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009). Estimated fossil fuel emissions over the hot spot region are ∼ 500-950 gC m −2 yr −1 as obtained from the global model simulation, EDGAR v4.2 and REAS v1.11 emission inventory. Simulated total fluxes show increasing trends, from 1.39 ± 1.01 % yr −1 (19.8 ± 1.9 TgC yr −1 ) to 6.7 ± 0.54 % yr −1 (97 ± 12 TgC yr −1 ) over the hot spot regions and decreasing trends of −0.95 ± 1.51 % yr −1 (−1 ± 2 TgC yr −1 ) to −5.7 ± 2.89 % yr −1 (−2.3 ± 2 TgC yr −1 ) over the sink regions. Model-simulated terrestrial ecosystem fluxes show decreasing trends (increasing CO 2 uptake) over the sink regions. Decreasing trends in terrestrial ecosystem fluxes imply that forest cover is increasing, which is consistent with India State of Forest Report (2009). Fossil fuel emissions show statistically significant increasing trends in all the data sets considered in this study. Estimated trend in simulated total fluxes over the Indian region is ∼ 4.72 ± 2.25 % yr −1 (25.6 TgC yr −1 ) which is slightly higher than global growth rate ∼ 3.1 % yr −1 during 2000-2010.

“…The former study was performed using a global emission inventory and the latter one uses an Asian emission inventory (Streets et al, 2003). However, recently a new gridded emission inventory of ozone precursors over the Indian geographical region have been prepared based on micro-level of all activity data (Dalvi et al, 2006;Beig and Brasseur, 2006) which are claimed to be better and found to be quite different than used by earlier modelers. Recently, Roy et al (2008) have used this new emission inventory in the regional 3-D chemistry transport model for Indian region but the impact of cumulative ozone exposure (AOT40) over the entire Indian region has not been reported so far.…”

Exposure-plant response of ambient ozone over the tropical Indian region

Abstract.A high resolution regional chemistry-transport model has been used to study the distribution of exposureplant response index (AOT40, Accumulated exposure Over a Threshold of 40 ppb, expressed as ppb h) over the Indian geographical region for the year 2003 as case study. The directives on ozone pollution in ambient air provided by United Nations Economic Commission for Europe (UNECE) and World Health Organization (WHO) for vegetation protection (AOT40) have been used to assess the air quality. A substantial temporal and spatial variation in AOT40 values has been observed across the Indian region. Large areas of India show ozone values above the AOT40 threshold limit (3000 ppb h for 3 months). Simulated AOT40 values are found to be substantially higher throughout the year over the most fertile Indo-Gangetic plains than the other regions of India, which can have an adverse effect on plants and vegetation in this region. The observed monthly AOT40 values reported from an Indian station, agree reasonably well with model simulated results. There is an underestimation of AOT40 in the model results during the periods of highest ozone concentration from December to March. We find that the simulated AOT40 target values for protection of vegetation is exceeded even in individual months, especially during November to April. Necessary and effective emission reduction strategies are therefore required to be developed in order to curb the surface level ozone pollution to protect the vegetation from further damage in India whose economy is highly dependent on agricultural sector and may influence the global balance.
