Muhammad Shahzaman,Weijun Zhu,Irfan Ullah,Farhan Mustafa,Muhammad Bilal,Shazia Ishfaq,Shazia Nisar,Muhammad Arshad,Rashid Iqbal,Rana Waqar Aslam +9 more
TL;DR: In this paper, the relationship between soil moisture, precipitation, terrestrial water storage (TWS), and vegetation condition index (VCI) was evaluated using the annual national production of barley, maize, rice, and wheat by computing the yield anomaly index (YAI).
Journal ArticleDOI
Remote Sensing Indices for Spatial Monitoring of Agricultural Drought in South Asian Countries
Muhammad Shahzaman,Weijun Zhu,Muhammad Bilal,Birhanu Asmerom Habtemicheal,Farhan Mustafa,Muhammad Arshad,Irfan Ullah,Shazia Ishfaq,Rashid Iqbal +8 more
TL;DR: In this article, the authors explore the performance of the evaporative stress index (ESI), vegetation health index (VHI), enhanced vegetation index (EVI), and standardized anomaly index (SAI) based on satellite remote sensing data from 2002-2019 for agricultural drought assessment in Afghanistan, Pakistan, India, and Bangladesh.
Journal ArticleDOI
Long-term spatiotemporal variations of aerosol optical depth over Yellow and Bohai Sea.
TL;DR: Significant differences in spatial distributions were found in different seasons in terms of area coverage as a maximum number of pixels were available during autumn, and regional high and low aerosol loadings were observed during autumn and summer, respectively.
Journal ArticleDOI
Validation of MODIS C6 Dark Target Aerosol Products at 3 km and 10 km Spatial Resolutions Over the China Seas and the Eastern Indian Ocean
TL;DR: Overall, this study found that ODLAOAOD observations for the DT3K and DT10K were much better than EODAOAOD, EODBOAOD and IODLAoaOD in terms of high correlation and a large percentage of the AOD retrievals within the Expected Error.
