Estimation of Ambient Air Quality in Delhi

Optimal Estimators for Ambient Air Quality Levels

-Procedures to estimate missing data, determine extrema, and derive uncertainties for data collected in ambient air monitoring networks are presented. The optimal linear estimators used obtain unbiased, minimum variance results based on the temporal and spatial correlation of the data and estimates of sample uncertainty. The first estimator interpolates missing data. The second estimator derive...

Ambient Air Quality Monitoring in Puducherry

During the summer of 2009, concentrations of oxides of nitrogen (NOx), oxides of sulphur (SOx), suspended particulate matter (SPM) and carbon monoxide (CO) were collected over successive periods of about 8 hour at eight sites. High volume air sampler was used to measure the concentration of oxides of nitrogen (NOx), oxides of sulphur (Sox), suspended particulate matter (SPM) and CO monitor was ...

The state of ambient air quality in Pakistan--a review.

BACKGROUND AND PURPOSE Pakistan, during the last decade, has seen an extensive escalation in population growth, urbanization, and industrialization, together with a great increase in motorization and energy use. As a result, a substantial rise has taken place in the types and number of emission sources of various air pollutants. However, due to the lack of air quality management capabilities, t...
