Oceancolor Data Downloader v1.1
##What it does This is a QGIS Plugin which allows easy download of oceancolor and sea surface temperature data from NASA Oceancolor.
It downloads either global level 3 mapped chlorophyll-a concentrations or sea surface temperatures within a defined time range, and resolution. The data is saved in GeoTiff format and can be added to the QGIS canvas once downloaded.
The plugin currently provides access to three datasets:
- MODIS AQUA CHL-a concentration
- SeaWiFS CHL-a concentration
- MODIS AQUA Night Sea Surface Temperatures
The plugin requires QGIS version 2.0 or higher. It can be installed via the Plugin Manager.

Install the plugin, named Oceancolor Downloader.
##Using the plugin
Select a dataset, a time period, a date range and a download path. Select whether you wish to add the composite to the map canvas.
If you have chosen to add the data to the canvas, it will appear styled once the GeoTiff is created. Sea surface temperature data will also include a seperate quality grid, but this will not be added to the canvas.
We are currently developing new features and working to improve existing ones. A selection of features we are looking to include in a future release are as follows:
- Alternative output file formats
- Options to subset output data to a lat/long bounding box
- Other datasets, such as Net Primary Production
- Progress bar
The plugin was developed by the Mapping and Geographic Information Centre at British Antarctic Survey.
