英文摘要

This paper describes the aerosols optical, physical characteristics and the aerosol radiative forcing pertaining to semi-arid region, Anantapur for the period January 2013-December 2014. Collocated measurements of Aerosol Optical Depth (AOD) and Black Carbon mass concentration (BC) are carried out by using MICROTOPS II and Aethalometer and estimated the aerosol radiative forcing over this location. The mean values of AOD at 500 nm are found to be 0.47 +/- 0.09, 0.34 +/- 0.08, 0.29 +/- 0.06 and 0.30 +/- 0.07 during summer, winter, monsoon and post-monsoon respectively. The Angstrom exponent (alpha(380-1020)) value is observed maximum in March (1.25 +/- 0.19) and which indicates the predominance of fine - mode aerosols and lowest in the month of July (0.33 +/- 0.14) and may be due to the dominance of coarse-mode aerosols.


The diurnal variation of BC is exhibited two height peaks during morning 07: 00-08: 00 (IST) and evening 19: 00-21: 00 (IST) hours and one minima noticed during afternoon (13: 00-16: 00). The highest monthly mean BC concentration is observed in the month of January (3.4 +/- 1.2 mu g m(-3)) and the lowest in July (1.1 +/- 0.2 mu g m(-3)). The estimated Aerosol Direct Radiative Forcing (ADRF) in the atmosphere is found to be +36.8 +/- 1.7 W m(-2), +26.9 +/- 0.2 W m(-2), +18.0 +/- 0.6 W m(-2) and +18.5 +/- 3.1 W m(-2) during summer, winter, monsoon and post-monsoon seasons, respectively. Large difference between TOA and BOA forcing is observed during summer which indicate the large absorption of radiant energy (36.80 W m(-2)) which contributes more increase in atmospheric heating by similar to 1 K/day. The BC contribution on an average is found to be 64% and is responsible for aerosol atmospheric heating. (C) 2016 Elsevier B.V. All rights reserved.
