The Strait of Malacca, located between Malay Peninsula and Sumatra, is a passage connecting the Pacific Ocean and the Indian Ocean. The annual average seawater transparency dataset of Malacca strait (2002-2017) 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 Malacca strait (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 36.76 m, which was in 2013; the minimum of seawater transparency was 0.002m, which was in 2004. Regionally, the average seawater transparency in 2007 was the lowest, at 15.55 m; while the average seawater transparency in 2005 was the highest, reaching 19.31 m, with a difference of 3.76 m. The spatial resolution of the dataset is 0.087003°. The dataset is consisted of 16 data files in .tif format with data size of 1.01 MB (Compressed to one single file, 157 KB).
