The product SEAICE_GLO_SEAICE_L4_NRT_OBSERVATIONS_011_001 contains spurious ice measurements in the ice concentration fields.
The principle causes of the spurious ice are believed to be as follows:
– Ice concentrations are now provided all the way to the coast, whereas this product had a zone along the coast with unclassified pixels.
Measurements near the coast can contain spurious ice, due to land spill over effects.
– this product had a T2m filter, which removed false ice where the 2m temperature from ECMWF was warmer than 8°C; however, this is no longer applied.
– Differences in how the old version product ice concentration algorithm is implemented compared the new version product may also be a factor.
Actions are in progress to remove the spurious ice.
