Mean Annual Total Precipitation
Mean annual precipitation, calculated from years 1994-2004, using daily station data from the GCOS Surface Network (GSN).
Classes of 10-Day Mean Annual Temperature
Unsupervised classification of the mean "10-day Temperature". The mean was calculated from years 1994-2004. 10-day gridded mean temperature layers (1km resolution) were aggregated and interpolated using daily station data from the GCOS Surface Network (GSN). The chosen number of classes is ten.
Trends in green biomass (NDVI)
The interpretation of green biomass trends needs to be done with care. An increasing or decreasing trend can have manifold causes and may indicate both improvement or deterioration.
From the drop down boxes below maps can be displayed showing trends in annual total green biomass production (accumulated NDVI) or in annual green biomass maximum (maximum NDVI). Trends were calculated for various periods between 1982 and 2004.
