ERS-1&2 SAR quantitative acquisitions in graphical form (since 1992)


The plots and histograms show over wide areas or in time the quantity of frames acquired by ERS-1 and ERS-2 SAR instruments. This information is extracted from the Central User Service (CUS) inventory at ESRIN, and is as reliable as the reports received from the stations.

The plots are related to the Phases C and G of ERS-1 and A of ERS-2. A few plots related to the Phases E and F of ERS-1 are given separately.

The plots and histograms can be freely reused, provided that the title and the ESA logo are kept.

Inventory Plots

They plot over the Earth map the number of frames acquired by the ERS-1 and ERS-2 SAR instruments in different ways.
The table header below... means...
Phases C/G/A - ERS-1&2 acquired during 35-days cycles
Phases E/F - ERS-1 acquired during 168-days cycles
