MODIS ET PML V2 - 500m - 8day¶
Description¶
The Penman-Monteith-Leuning Evapotranspiration V2 (PML_V2) products include evapotranspiration (ET), its three components, and gross primary product (GPP) at 500m and 8-day resolution during 2002-2017 and with spatial range from -60 degS to 90 degN. The major advantages of the PML_V2 products are: coupled estimates of transpiration and GPP via canopy conductance (Gan et al., 2018; Zhang et al., 2019), partitioning ET into three components: transpiration from vegetation, direct evaporation from the soil and vaporization of intercepted rainfall from vegetation (Zhang et al., 2016).
