Air pollution in many of India's cities exceeds national and international standards, effective control strategies require knowledge the sources that contribute to air their spatiotemporal variability. In this study, we examine influence a single source, outdoor biomass burning, on particulate matter (PM) concentrations, surface visibility, aerosol optical depth (AOD) from 2007 2013 three most populous Indian cities. We define upwind regions, or "airsheds," for by using atmospheric back...
Models of atmospheric composition rely on fire emissions inventories to reconstruct and project impacts biomass burning air quality, public health, climate, ecosystem dynamics, land-atmosphere exchanges. Many such global use satellite measurements active fires and/or burned area from the Moderate Resolution Imaging Spectroradiometer (MODIS). However, differences across in interpretation imagery, factors assumed for different components smoke, adjustments made small obscured can result large...
Since at least the 1980s, many farmers in northwest India have switched to mechanized combine harvesting boost efficiency. This technique leaves abundant crop residue on fields, which typically burn prepare their fields for subsequent planting. A key question is what extent large quantity of smoke emitted by these fires contributes already severe pollution Delhi and across other parts heavily populated Indo-Gangetic Plain located downwind fires. Using a combination observed modeled...
High levels of PM 2.5 during the 2020 wildfires in western United States led to an excess COVID-19 cases and deaths.
Crop residue burning contributes to poor air quality and imposes a health burden on India. Despite government bans other interventions, this practice remains widespread. Here we estimate the impact of changes in agricultural emissions across India quantify potential benefit district-level actions using an adjoint modeling approach. From 2003 2019, find that caused 44,000-98,000 particulate matter exposure-related premature deaths annually, which Punjab, Haryana, Uttar Pradesh contribute...
Abstract. Tropospheric nitrogen dioxide (NO2) measured from satellites has been widely used to track anthropogenic NOx emissions, but its retrieval and interpretation can be complicated by the free tropospheric NO2 background which satellite measurements are particularly sensitive. vertical column densities (VCDs) spaceborne Ozone Monitoring Instrument (OMI) averaged over contiguous US (CONUS) show no trend after 2009, despite sustained decreases in implying an important rising contribution...
A rising source of outdoor emissions in northwestern India is crop residue burning, occurring after the monsoon (kharif) and winter (rabi) harvests. In particular, post-monsoon rice which occurs annually from October to November linked increasing mechanization, coincides with meteorological conditions that enhance short-term air quality degradation. Here we examine Global Fire Emissions Database (GFED), whose bottom-up are based on 500-m burned area product, MCD64A1, derived Moderate...

Fire seasons have become increasingly variable and extreme due to changing climatological, ecological, social conditions. Earth observation data are critical for monitoring fires their impacts. Herein, we present a whole-system framework identifying synthesizing fire objectives needs throughout the life cycle of event. The four stages using include following: (1) pre-fire vegetation inventories, (2) active-fire monitoring, (3) post-fire assessment, (4) multi-scale synthesis. We identify...
Sweetpotato (<italic>Ipomoea batatas</italic> (L.) Lam.) is a globally cultivated root crop of paramount significance. The hexaploid genome, known as 'Taizhong 6', has been sequenced and serves crucial reference genome for sweetpotato related species within the Convolvulaceae family. However, current annotation relies primarily on <italic>ab initio</italic> predictions and, to lesser extent, transcriptome datasets, which only predict coding sequences. Therefore, an improved highly desirable....
Abstract. Wildfires can have a significant impact on air quality in Australia during severe burning seasons, but incomplete knowledge of the injection heights smoke plumes poses challenge for quantifying exposure.
