VIIRS striping and M1/M2 band comparisons to MODIS
Posted: Thu Jun 30, 2022 1:33 pm America/New_York
Hi everyone,
I'm comparing the VIIRS-SNPP times series to MODIS-Aqua and noticing an increase of striping in recent years (~2017-present). It's less noticeable in OCx chlorophyll-a, but very obvious in GSM (screenshot of 8day log10 chlorophyll images using the GSM_GS algorithm from Clay et al 2019, from June 18-25 around Nova Scotia). Around the same timeframe, there was a decrease in the M1 band relative to MODIS, and an increase in the M2 band.
I'm pretty new to the striping issues in VIIRS and how they have been corrected in past reprocessings... Are there plans to correct the striping in the next VIIRS reprocessing? Are the decrease/increase in the M1/M2 bands related to the striping, and will they be corrected at the same time?
