Fraction of Photosynthetically Active Radiation (FPAR) - AVHRR


These data describe the Australia-wide, monthly fraction of Photosynthetically Active Radiation absorbed by vegetation (fPAR) derived from Advance Very High Resolution Radiometer data spanning July 1981 to Oct 2011. FPAR is linearly related to fractional foliage cover. Here fPAR is split into that of persistent vegetation and of recurrent vegetation, which represent non-deciduous perennial vegetation and annual, ephemeral and deciduous vegetation, respectively. Data have been processed using the "invariant cover triangle" method to remove the majority of errors introduced by sensor calibration and change-over effects.

This dataset has been developed by the Time Series Remote Sensing Team, CSIRO Land and Water in conjunction with the Environmental Biology Group at the Australian National University. The original data were supplied by CSIRO Marine and Atmospheric Research. This work has been supported by the eWater CRC.

Data are suited to the analysis of long-term dynamics (trends) in vegetation cover. Data are monthly grids of 0.08 degree cell size from July 1981 onwards and of 0.01 degree from Feb 1995 onwards.


ENVI data are available from CSIRO DAP,
