Sea ice in the Arctic and Antarctica (1992-2018)

The visualization simultaneously shows the development of the sea ice concentration for the period 1992-2018 for the Arctic and the Antarctic based on the ASI-SSMI satellite data.

Observed precipitation climatology on the basis of HOAPS-3, the "Hamburg Ocean Atmosphere Parameters and Fluxes from Satellite Data"


This animation shows the surface albedo (the reflectivity of a surface) for 1981 to 2005 for the continent of Africa and, at the same time, the temporal evolution of climatological albedo anomalies for the Sahel.

Vegetation and Albedo

The visualization of the NDVI vegetation index and the surface albedo, both based on satellite observations, shows the spatio-temporal dynamics of the vegetation in Africa.
