CYAN Data 2012-2016

by joeearles » Mon Jan 05, 2026 4:54 pm America/New_York

Does anyone know why there is no CYAN data available between 2012 and 2016?

The ENVISAT MERIS Regional Binned Cyanobacteria Index (CI) Data (https://www.earthdata.nasa.gov/data/catalog/ob-cloud-meris-l3b-cyan-6.0) covers between March 2002 and May 2012.

The Merged Sentinel-3A and Sentinel-3B OLCI Regional Mapped Cyanobacteria Index (CI) Data (https://www.earthdata.nasa.gov/data/catalog/ob-cloud-merged-s3-olci-l3m-cyan-6.0) covers between April 2016 and the present, but it seems like there is a gap in data for the years in between.

Does anyone know if there is any way to access this data between these years, or is it lost?

Hello,

Only the two sensors were involved in the CyAN project. Since the Envisat/MERIS mission ended in 2012 and Sentinel-3A/OLCI mission didn't begin until 2016, the years in between the two were not able to be captured. Here is more information about the project https://www.earthdata.nasa.gov/data/projects/cyan
