Global Seasonal Landcover in 2004




Global Seasonal Landcover in 2004.


This animation shows a global rotation of seasonal changes in landcover. Landcover fades from month to month, and is displayed at a rate of two months per second. This version is in HD widescreen format and has a date bar indicating the month being shown.


This visualization of the data set shows seasonal variations such as snowfall, spring greening and droughts in a seamless fashion, thereby heightening awareness of changes in the Earth's climate. Here we tour the globe, viewing seasonal land cover over many continents.


This data set is derived from imagery taken in 2004 by the MODIS instrument on the Terra satellite.
