ePiSaT software version 1.0 released !

The ePiSaT software has been released. The code and sample OzFlux data can be downloaded from:

https://github.com/belgaroo/ePiSaT-ecosystem-Production-in-Space-and-Time

The package and code is self explanatory, enabling the user to partition flux data to generate an estimate of GPP. ePiSaT users wanting to replicate the project can download more OzFlux data directly:

http://www.ozflux.org.au/

Please note that there have been some subtle changes to previously-posted details on how and where the ePiSaT software will be released. This post details the first official release of the ePiSaT software.

Background


Ecosystem Production in Space and Time (ePiSaT) models Gross Primary Production (GPP) across the Australian continent from OzFlux flux tower data, gridded climate and satellite (MODIS) data. ePiSaT can be used to estimate ecosystem variables by partitioning OzFlux eddy covariance data to estimate GPP, light use efficiency (LUE), the maximum rate of carboxylation (Amax) etc. Once determined, the ePiSaT-modelled variables can be used in the well-founded and tested LUE approach to estimate GPP. Sample OzFlux data from Howard Springs is provided; ePiSaT requires the user to provide fAPAR, observed radiation, temperature and humidity data.
