Australian land surface phenology dataset at 500m resolution
The Australian Phenology Product is a continental data set that allows the quantitative analysis of Australia’s phenology derived from MODIS Enhanced Vegetation Index (EVI) data using an algorithm designed to accommodate Australian conditions, described in Xie et al. 2023. The product can be used to characterize phenological cycles of greening and browning and quantify the cycles’ inter and intra annual variability from 2003 to 2018 across Australia. Phenological cycles are defined as a period of EVI-measured greening and browning that may occur at any time of the year, extend across the end of a year, skip a year (not occur for one or multiple years) or occur more than once a year. Multiple phenological cycles within a year can occur in the form of double cropping in agricultural areas or be caused by a-seasonal rain events in water limited environments. Based on per-pixel greenness trajectories measured by MODIS EVI, phenological cycle curves were modelled and their key properties in the form of phenological curve metrics were derived including: the first and second minimum point, peak, start and end of cycle; length of cycle, and; the amplitude of the cycle. Integrated EVI under the curve between the start and end of the cycle time of each cycle is calculated as a proxy of productivity.

- Purpose
- Land Surface Phenology (LSP) provides valuable information to scientists and practitioners interested in vegetation and ecosystem response to climate variability such as drought and land use change. Specific applications of LSP information include for example the quantification of crop yields, wildfire fuel accumulation, ecosystem resilience and health and land surface modelling.

Report
Result
- Statement
- Validation of seasonal/phenologic parameters is accomplished across a wide range of Australian landscapes through comparisons with finer resolution (half-hourly/ daily) OzFlux eddy covariance tower measures of gross primary productivity (GPP). Tower measurements derived photosynthetic activity (GPP) primarily relate to onset, duration, magnitude, and growing season length. At regional levels, we plan validation activities focused on the use of phenocam networks that capture the seasonal dynamics and species-level phenology of overstory and understory plant functional types. This is being prototyped in NSW and thenceforth to be expanded to TERN supersites, and transects.
Resource lineage
- Statement
- Python programming was used to download and process data. Phenology extraction algorithm was designed by Qiaoyun Xie and described in Xie et al. 2022.
