Abstract：

Annual average seawater transparency dataset in the sea area 40 km offshore from Chabahar (Iran) to Ormara (Pakistan) (2002-2017) covering 40km offshore seawaters from coastline of the Chabahar (Iran)- Ormara (Pakistan). The dataset was developed based on annual average global water body reflectance data (MODISA_L3m_RRS v2018). Firstly, the seawater transparency was calculated by empirical inversion model proposed by Tian Lin in 2013, and then clipped it to get the annual average seawater transparency dataset in the sea area 40 km offshore from Chabahar (Iran) to Ormara (Pakistan) (2002-2017). The data result shows that the seawater transparency from far shore to nearshore showed gradually decreasing trend. The maximum of seawater transparency from 2002 to 2017 was 22.01 m, which was in 2016; the minimum of seawater transparency was 0.001 m, which was in 2003. Regionally, the average seawater transparency in 2008 was the lowest, at 8.66 m; while the average seawater transparency in 2015 was the highest, reaching 13.31 m, with a difference of 4.65 m. The data spatial resolution is 0.083027°. The dataset is consisted of 16 data files in .tif format with data size of 1.02 MB (Compressed to one single data file, 50.8 KB).
