Analyzing the time series changes trend of the Aerosol Optical Depth (AOD) index of Terra satellite’s MODIS sensor for Jazmorian basin in the southeast of Iran during 2000-2018

The present study aimed at investigating the time series changes of aerosols optical depth (AOD) index on a monthly basis in Jazmorian Basin in the southeast of Iran using remotely sensed satellite data. To this end, the monthly data of aerosol optical depth (AOD) index from MODIS sensor of Terra Satellite were applied for an 18-year period (2000-2017). After preparing the monthly time series of AOD index, classical linear regression was employed for examining the changes’ trend of this index. The study results indicated that AOD index changes’ trend has been significant in α=0.05 probability level only for January during which an ascending trend has been documented. The changes’ trends were also found significant for February, April and May, whose probability level was α=0.1. The changes’ trends of AOD was also found ascending during these three months alike January. Disregarding these four months, no significant trends were observed in the other studied months in terms of the changes’ trends of aerosol optical depth (AOD) in Jazmorian Basin
