Question about the CER_GEO_ED4_HIM08 product

We notice that the spatial resolution of CER_GEO_ED4_HIM08 product is
The observations are at 4 km resolution (at nadir) and are sub-sampled to 8 km.
We want to know why do you sub-sample the data? Why is it different at different hemisphere?

Hello,

Both NH & SH hemispheres are at the same resolution. The observations are at 2 km resolution (at nadir) and are sub-sampled to 6 km. Thanks for bringing it to our attention. We will fix the NH description. The sub-sampled resolution meets the needs of the CERES project without having a data implosion.

Regards,
ASDC
