MODIS Derived Chlorophyll a dataset: Seasonal Means

The dataset measures the long-term seasonal means of the chlorophyll a concentrations of ocean surface waters. They are derived from MODIS (aqua) images using NASA's SeaDAS image processing software. The monthly chlorophyll a images between July 2002 and December 2016 are used to calculate the means of the four austral seasons: winter (June, July, and August), spring (September, October and November), summer (December, January and February) and autumn (March, April and May). The extent of the dataset covers the entire Australian EEZ and surrounding waters (including the southern ocean). The unit of the dataset is mg/m3.

本数据集用于测定海洋表层水体叶绿素a浓度的长期季节均值。数据源自MODIS（Aqua）影像，通过美国国家航空航天局（NASA）的SeaDAS图像处理软件生成。2002年7月至2016年12月期间的月度叶绿素a影像被用于计算南半球四个季节的均值：冬季（6月、7月、8月）、春季（9月、10月、11月）、夏季（12月、1月、2月）及秋季（3月、4月、5月）。数据集覆盖范围包括整个澳大利亚专属经济区（EEZ）及周边水域（含南大洋）。数据集的单位为毫克每立方米（mg/m³）。
