Are Rrs data available for bands in the near-IR/IR, e.g. 746nm (M6)? If not, is there a recipe for generating these data? Thanks

Rrs_746 is not included in VIIRS L2 OC suite.

You can download L1A and GEO here https://oceandata.sci.gsfc.nasa.gov/directdataaccess/
and generate your own L2 file with Rrs_746 by doing l2gen on VIIRS L1A + GEO, with Rrs_746 added to Selected Products on The Products Tab

Thank you. I will try this tomorrow.

While Bing's response is correct, you should bear in mind that unless you change the bands used in the aerosol selection process, the Rrs in the NIR channels will not be "measured", but rather the output of the model used in the "NIR-correction" algorithm.
