PARASOL, launched in December 2004, and after a 5 years mission inside the so-called A-train atmospheric orbital
observatory together with Aqua, Aura, Calipso, and Cloudsat, is now flying on a slightly lower altitude and will continue
its observation for several months. Evolution with time of the sensor's behaviour is a natural process. A decrease of the
radiometric sensitivity has been detected an corrected. Because there is no on-board calibration device, this correction
was based on an innovative technique developed using deep convective clouds and their remarkable spectral properties.
This operational method has been previously published (Fougnie and Bach, 2007). This evolution, larger for shorter
wavelengths, reaches nearly 10% for band 490, and 2% for band 865 after 5 years of mission. This estimation was
established for "nadir/zenith" geometrical conditions. This means that it represents the evolution of the central part of the
camera's field of view. We generalize here the method and results to other geometric configurations. It was possible to
derive a 2D-mapping of the evolution for all the camera's field of view. This result was validated through other methods
using different natural targets. The accuracy of the method is evaluated to a few tenth of percents after 5 years.
