TL;DR: The authors assesses the skill of current-generation global atmospheric chemistry models in simulating the observed present-day tropospheric ozone distribution, variability, and trends using a range of model evaluation techniques, and demonstrate that global chemistry models are broadly skillful in capturing the spatio-temporal variations of troposphere ozone over the seasonal cycle, for extreme pollution episodes, and changes over interannual to decadal periods.

Sachin D. Ghude,D. M. Chate,Chinmay Jena,Gufran Beig,Rajesh Kumar,Mary C. Barth,Gabriele Pfister,Suvarna Fadnavis,Prakash Pithani +8 more
TL;DR: This bottom-up modeling study, supported by new population census 2011 data, simulates ozone (O3) and fine particulate matter (PM2.5) exposure on local to regional scales and quantifies, present-day premature mortalities associated with the exposure to near-surface PM2.3 and O3 concentrations in India using a regional chemistry model.

Characteristics of aerosol black carbon mass concentration over a high altitude location in the Central Himalayas from multi-year measurements
Umesh Chandra Dumka,Umesh Chandra Dumka,K. Krishna Moorthy,Rajesh Kumar,Prashant Hegde,Ram Sagar,P. Pant,Narendra Singh,S. Suresh Babu +8 more
TL;DR: In this paper, multi-year measurements of near surface aerosol black carbon (BC) mass concentration, made from a high altitude station at Manora Peak (29.4° N, 79.5° E, 1958 mmsl) in the Central Himalayas, using a 7-channel Aethalometer for 38 months from November 2004 to December 2007, are examined.
Journal ArticleDOI
Simulations over South Asia using the Weather Research and Forecasting model with Chemistry (WRF-Chem): chemistry evaluation and initial results
TL;DR: In this paper, the authors presented annual simulations of tropospheric ozone and related species made for the first time using the WRF-Chem model over South Asia for the year 2008.
Journal ArticleDOI
WRF-Chem simulations of a typical pre-monsoon dust storm in northern India: influences on aerosol optical properties and radiation budget
TL;DR: In this article, the impact of a typical pre-monsoon season (April-June) dust storm event on the regional aerosol optical properties and radiation budget in northern India is analyzed.
