GOES-16 and Himawari-8 L2P SST are now available
NOAA CoastWatch/OceanWatch is now distributing GOES-16 SST (GHRSST L2P) and Himawari-8 SST (L2P). The data are updated once per hour with a two-week rotating buffer.

Click here to access the Himawari-8 data: ftp://ftp.star.nesdis.noaa.gov/pub/socd4/coastwatch/sst/nrt/ahi/
Please remember that legacy GOES-13 SST will be discontinued. See news item below for further information.
GOES-16 will replace GOES-13 in November 2017
NOAA CoastWatch/OceanWatch SST products will transition from GOES-13 data to GOES-16 data in November 2017. Please note that legacy GOES-13 SST products (gridded, in binary format) will be discontinued. We apologize for any inconvenience or disruptions that this discontinuation may cause but we are looking forward to a new era of high quality GOES-SST products.
Two GOES-16 products will be offered during the initial transition:
• Advanced Clear-Sky Processer for Oceans (ACSPO) L2P full-disk GHRSST GDS 2.0. This product will be offered in NetCDF4 format at a one hour frequency with data sets of ~260 MB/hour or ~6.3 GB/day.
• ACSPO L3U gridded GHRSST GDS 2.0. This product will be offered in NetCDF4 format at a 0.02 degree grid spacing (~2 km) with data sets of ~0.5 GB/day.
Please note that these products will have 8 hour x 5 day/week technical support (as opposed to 24 hour x 7day/week). Future updates (ACSPO v2.51/2.60) will include "collated" counterparts to L2P/L3U (L2C/L3C, respectively). The L2C/L3C products will use temporal consistency analyses and have improved coverage and better performance. To provide feedback on your GOES-16 SST data needs, please contact the CoastWatch/OceanWatch help desk at firstname.lastname@example.org.
Good news! The NOAA VIIRS Science Quality Ocean Color Level 2 Environmental Data Record products have been improved. Currently, CoastWatch is replacing the entire mission-long dataset with the new dataset from MSL12 v1.21 reprocessing. The new dataset will be available August 9,2017. Please check back soon to access full mission, MLS12 v1.21 VIIRS ocean color products.
Thanks for your interest in CoastWatch data. Please consider signing up for our mailing list for future announcements.
Level-2 and Level-3 OLCI datasets are now available.
NOAA CoastWatch/OceanWatch is now distributing Sentinel-3 OLCI Level-2 and Level-3 ocean color datasets. Data is provided courtesy of EUMETSAT as part of the Copernicus Program. NOAA CoastWatch will be increasing product coverage over the next month.
For more information, please refer to our OLCI near real-time product page.
Level-3 daily sea level anomaly datasets are now available.
NOAA CoastWatch/OceanWatch is now distributing daily Level-3 sea level anomaly datasets produced by the NOAA Laboratory for Satellite Altimetry. The datasets are produced globally with near-real time data from a constellation of radar altimeter missions.

Reanalysis products for ACSPO SST are now available for VIIRS (Level-2P and Level-3U) and AVHRR (Level-2P).
Sea Surface Temperature products for VIIRS and AVHRR have been reanalyzed by NOAA’s Advanced Clear-Sky Processor for Oceans (ACSPO) using NOAA’s enterprise algorithm.
The VIIRS reanalysis is available at Level-2P and Level-3U and the AVHRR is reanalysis is available at Level-2P.

Level-1B OLCI-Sentinel-3A data now available.
True color image produced today (15 February 2017) by NOAA CoastWatch/OceanWatch from OLCI-Sentinel-3A data.
As of July 7, 2017 EUMETSAT OLCI Level 2 ocean color data products are released. Products are available through CoastWatch/OceanWatch. In accordance with a Technical Arrangement with EUMETSAT, NOAA is the primary provider of Sentinel-3 marine data for the US. OLCI data can be accessed through CoastWatch/OceanWatch using the granule selector tool.
From this tool, users can select granules of regions and dates of interest and view and download PNG true color images or download data files in either EUMETSAT TAR or CoastWatch HDF data formats. Multiple files can be downloaded at one time by selecting each granule of interest and clicking the "+" to add file names to the data cart, then automatically generate a list of those files to use in a download script (e.g., wget, etc.).

S-NPP VIIRS Life-of-Mission Science Quality Level-2 Ocean Color products are available.
Version 3.3.2 of the CoastWatch Utilities CoastWatch Data Analysis Tool (CDAT) is now available.
