Full description

This GIS data layer shows the frequency of coastal upwelling along the south-eastern coast of Australia. The higher data values indicate areas of persistent and semi-persistent upwelling; while, the medium data values indicate areas of seasonal upwelling. The data was generated using 14 years of monthly MODIS SST data. Please refer to this publication: "Huang, Z., & Wang, X.H. (2019). Mapping the spatial and temporal variability of the upwelling systems of the Australian south-eastern coast using 14-year of MODIS data. Remote Sensing of Environment, 227, 90-109" (https://doi.org/10.1016/j.rse.2019.04.002) for details of the MODIS data and the upwelling mapping method.

Statement: The data was generated using 14 years of monthly MODIS SST data. The followings are the key steps: 1. Monthly composited MODIS SST data were generated from 14 years (July 2002 to December 2016) daily MODIS SST images obtained from the Integrated Marine Observing System (IMOS; http://imos.org.au/). 2. The upwelling areas in the 126 of these monthly SST data for the months between September and May (inclusive) were mapped. 3. The 126 upwelling maps were combined to calculate the count and then the frequency of the upwelling at each cell location (this data layer). 4. The frequency data was then classified into five categories: a. <10% unlikely; b. 10-30% occasional/semi-seasonal; c. 30-50% seasonal; d. 50-70% semi-persistent; e. >70% persistent.
