8-day evapotranspiration global mod16a2 modis


The MOD16A2 V105 product provides information about 8-day global terrestrial evapotranspiration at 1km pixel resolution. Evapotranspiration (ET) is the sum of evaporation and plant transpiration from the Earth's surface to the atmosphere. With long-term ET data, the effects of changes in climate, land use, and ecosystems disturbances can be quantified.

The MOD16A2 product is produced by the Numerical Terradynamic Simulation Group NTSG, University of Montana (UMT) in conjunction with NASA Earth Observing System. For more details about the algorithm used see the algorithm theoretical basis document.

  • The period of coverage is 8 days with the exception of the last period at the end of the year which is either 5 or 6 days. ET/PET units are 0.1mm/5-day for December 27-31 of 2001, 2002, 2003, 2005, 2006, 2007, 2009, 2010, and 0.1mm/6-day for December 26-31 of 2000, 2004, 2008 (leap years).

** For some pixels in African rainforest, the MODIS albedo data from MCD43B2/MCD43B3 have no cloud-free data throughout an entire year. As a result, pixels for that year in all data bands are masked out.
