Australia’s Environment

This interactive data explorer shows national-scale information on land cover, forest cover, bushfire, water availability, landscape health, carbon storage, and rivers and wetlands. The information can be accessed as interactive maps and as environmental accounts and graphs, allowing all data to be examined by region and land cover type, to be compared to preceding years, or to be downloaded for further analysis.

Asia-Pacific Water Monitor

The Asia-Pacific Water Monitor uses satellite and on-ground measurements, weather forecasts and a hydrological model to produce near-real time water balance estimates for the Asia-Pacific region. Maps show precipitation, streamflow, catchment water storage, and evapotranspiration. Information is presented as actual values, deciles, anomalies and percentage of average. Information is available for daily totals and 30-day averages. [link]


W3 and AWRA-L landscape hydrology models

The World-Wide Water model (W3) and its predecessor, the Australian Water Resources Assessment Landscape model (AWRA-L), are two near-identical models for grid-based estimation of daily water balance dynamics and water-related vegetation dynamics. The example Matlab implementation of W3 model is freely available for download. You can find the code, relevant literature, and some course material here.



Data sets

MSWEP : Multi-Source Weighted-Ensem­ble Pre­cip­i­ta­tion

is a new global terres­trial pre­cip­i­ta­tion (P) dataset (1979–2015) with a high 3-hourly temporal and 0.25° spa­tial res­o­lu­tion (Beck et al., 2016). The dataset is unique in that it takes advan­tage of a wide range of data sources, includ­ing gauge, satel­lite, and reanaly­sis data, to obtain the best pos­si­ble P esti­mates at global scale. download data [Australia (THREDDS)Europe (FTP)]

Global Water Cycle Reanalysis

Estimates of monthly average water storage in different components of the water cycle for 2003-2012 at 1⁰. Estimates were derived by assimilating satellite data into a model ensemble. Data are available for sub-surface (soil and groundwater) storage and storage in ice & snow, rivers, lakes, and oceans.

Global Canopy Conductance

Canopy conductance at a global scale based on three vegetation indices (NDVI, EVI and Kc) derived from the MODIS MCD43C4 reflectance product. The data is produced globally at 0.05⁰ and every 8 days. Monthly and annual climatologies are also available.
