Type of data	Figure
How data was acquired	Survey and computer simulation using the Global Nested Air Quality Prediction Modeling System
Data format	Raw and Analyzed
Description of data collection	• The large-scale harmful algal bloom events were collected from the Marine Environmental Quality Bulletin of China (http://www.coi.gov.cn/hygb) • Global Nested Air Quality Prediction Modeling System [2], [3], [4] were used to simulate the atmospheric transport and deposition flux of nutrient.
Parameters for data collection	• The harmful algal bloom event with an area larger than 1000km2 in the East China Sea during 2006. • The harmful algal bloom event (a spatial coverage of 1000km2), which developed in coast water off Zhejiang, China between the 3rd- the 8th of May 2006, was use as research case. Then the Global Nested Air Quality Prediction Modeling System was used to simulate the atmospheric transport and deposition flux of nutrient in algal bloom area.
