Mapping spatial distribution of particulate matter using Kriging and Inverse Distance Weighting at supersites of megacity Delhi
TL;DR: In this article, the authors used two widely used spatial interpolation techniques (Kriging and IDW) by predicting their concentrations at distinct unmonitored locations, which can help in policy formulation and decision making by providing aid in spatial and temporal variability.
Journal ArticleDOI
Preliminary estimates of nanoparticle number emissions from road vehicles in megacity Delhi and associated health impacts.
TL;DR: Preliminary estimates of ToN emissions from road vehicles, roadside and ambient ToN concentrations, and exposure related excess deaths in Delhi in current and two future scenarios; business as usual (BAU) and best estimate scenario (BES).
Journal ArticleDOI
A review on recent progress in observations, sources, classification and regulations of PM2.5 in Asian environments
TL;DR: A critical synthesis of literature suggests a lack of exposure and monitoring studies to inform personal exposure in the household and rural areas of Asian environments, and the synthesis of regulatory guidelines and future perspectives for PM2.5 in Asian countries is concluded.
Journal ArticleDOI
Measurements of particles in the 5–1000 nm range close to road level in an urban street canyon
TL;DR: The main aims of the measurements were to investigate the dependence of particle number distributions and concentrations and their vertical variations on wind speed, wind direction, traffic volume, and to estimate the particle number flux (PNF) and the particles number emission factors (PNEF) for typical urban streets and driving conditions.

TL;DR: In this article, the authors obtained the spatiotemporal characteristics of daily-averaged particulate matter (PM10 and PM2.5) and trace gases (NOX,O3,SO2, and CO) within a network of 12 air quality monitoring stations located over 2000 km2 across Delhi-NCR from January 2014 to December 2017.
