Notes:
- VIIRS Near-Real-Time (NRT) products are produced from original IDPS SDR and ancillary data from the Global Forecast System (GFS) model.
VIIRS Science-Quality (SCI) products are produced from recalibrated Ocean Color SDR (OC-SDR) and science quality (reanalysis) ancillary data. - The current data processing versions are NRT_IDPS_V1.21 (forwarding since March 19, 2017) for NRT and SCI_OC04.0_V1.21 (reprocessed in April 2017 and forwarding) for SCI products, respectively. The MSL12 is currently v1.21 and SCI OC SDR is v4.0.
- VIIRS NRT products before Feb. 6, 2012 are not reliable or usable due to VIIRS instrument calibration error in IDPS SDR.
- The VIIRS nominal center wavelengths (different from the specification) are as follows (units in nm):
M1:410, M2:443, M3:486, M4:551, M5:671, M6:745, M7:862, M8:1238, M10:1601, M11:2257 - The details on VIIRS MSL12-NIR water reflectance correction algorithm (BMW) can be found in Jiang and Wang (2014).
- VIIRS MSL12-SWIR uses M8 and M10 as the two atmospheric correction bands as described in Wang et al. (2007).
- The VIIRS Kd(490) data are derived using Wang et al. (2009) algorithm.
- The VIIRS Kd(PAR) data are derived using Son and Wang (2015) algorithm.
- VIIRS chlorophyll-a, Kd(490), Kd(PAR) and nLw(λ) products are post-processed to remove striping as described in Mikelsons et al. (2014). The destriping software can be downloaded here.
- Evaluation Products: The VIIRS PAR algorithm was provided by Robert Frouin and implemented in MSL12 by STAR Ocean Color Research Team; The VIIRS IOP products are derived using the Quasi-Analytical Algorithm (QAA) from Lee et al. (2002); The VIIRS OCI Chl-a product is derived using Wang and Son (2016); The VIIRS QA score is derived based on Wei et al. (2016).
- User Specific Products (MSL12-NIR only): The VIIRS Chl-a anomaly was calculated using the 61-day median Chl-a following Stumpf et al. (2003), and we have also added Chl-a anomaly ratio (Chl-a anomaly/61-day median Chl-a).
