Summary of THREDDS data for AusEnv Project¶
All data can be found in the /au/ subdirectory of our THREDDS drive. In principle they should be largely self described, but a bit of summary below.
You can find the following data collections:
/au/treecover¶
Landsat scale (25m) mapping of forest extent for each year as well as a file showing the change in forest area between 2013-2015. These are large files, opening them in their entirety is not recommended and will freeze e.g. Panoply.
Functionality required: to select a year and data type (i.e. forest cover or change) and look continentally or zooming in to any area.
/au/owl/¶
Inundated area mapping for 8-day periods based on MODIS 500m, collected in annual files. The date provided is the start date of the 8-day period.
/au/OzWALD/owl/ is the same data, upsampled to 0.05 degree resolution.
Functionality required: to select a date and look continentally or zooming in to any area. I also added annual summary data for annual maximum, mean and minimum extent. These also need to be mapped.
/au/Ramsar/¶
This has numbered files, each of which represents a so-called “Ramsar” (i.e. ecologically important) wetland or part thereof. The file has maximum water extent for a series of years derived from Landsat mapping, as well as layers showing the Last year pixels were inundated and dry, resp.
Functionality required: to first select a Ramsar wetland from a map with symbols, which will automatically zoom in on the geographic data extent. Select a data type (i.e. max water extent for a particular year or the last year since.. ).
/au/OzWALD/daily/¶
This has annual files each with a different variable at daily time step and 0.05 degree resolution.
Functionality required: select data and variable and get it visualised.
(similar to www.bom.gov.au/water/landscape/)
Among these, the data AWRA.daily.GPP.* have the highest priority.
Note
I will also be generating a file with monthly and annual average values and annual average anomalies from mean. Similar functionality will be required.
