Publicly available timeseries and trend data
The following are final results and intermediate outputs from this work. These are freely and publicly available, under Creative Commons CC-BY 4.0 license:
(Tabular data) Estimated annual trends of change in surface water area for dry season, wet season and permanent water, for river basins and reaches.
(Tabular data) Timeseries of surface water area for dry season, wet season and permanent water, aggregated for river basins and reaches.
(Raster data) Historical pixel-wise surface water occurrence for dry season, wet season and permanent water, for each year from 1991 to 2020, at 30m/pixel resolution.
The file sizes of these data assets are starkly different, necessitating different ways of disseminating and utilizing them. While the estimated annual trends and the historical timeseries of surface water areas are relatively small-sized files (a few tens of MBs), the historical pixel-wise seasonal water occurrence rasters are large (> 10GB). Hence, there are different ways to accessing them, and they are as follows:
Annual trends in surface water change can be accessed publicly and for free from a public scienfitic data repository on Zenodo.
In addition, outputs of intermediate steps of our analysis have also been made available, on the Google Earth Engine cloud platform.
All our data and results can be accessed in the GEE cloud processing platform. Since most of these large data assets are too big to be handled or analysed by most typical personal computers, accessing and analysing them in-full directly in GEE usually works best.
A timeseries of seasonal surface water areas, for a chosen few basins or reaches, can be downloaded as a CSV file. This can help with explorations of trends over relatively small areas (at local or regional scales).
