Hi,

Is there an issue with these products?
Do you know when then will be available?

Thanks,
Julien

Hi Julien,

The delay for refined products does not seem unusual to me,
but I am seeing MODIS quicklook products.

Hi Norman,

Yes there are MODIS QLP products but no QL since 2020-04-14, and same for VIIRS with QL and RF.
We observed that usually VIIRSx RF and MODISx QL are available at J+15 (and we are at J+21), so my message is just to check that there is no issue in the processing chain.

Thansk,
Julien

I will leave it to others to say why recent MODIS products have not advanced
beyond preliminary quicklook versions, but I do see that fairly recent VIIRS
products have. For example, for this file.

ncdump -h V2020126055400.L2_SNPP_OC.nc | grep processing_version
:processing_version = "2018.0QL" ;

Yes for VIIRS the delay is not on QL products but on RF, because (if I'm not wrong) the VIIRS RF consolidation is the same than the MODIS QL.
