Users of VIIRS ocean color products should be aware of a processing anomaly that affected products for the days of 16 and 17 January 2020. The source of the problem in the satellite data records (SDR; i.e., Level 1) has been resolved as of 18 January production. CoastWatch will be assessing impacts on CoastWatch products (environmental data records EDR or Level 2; and higher level processing, Level 3, Level 4) for this period. Some data files may be flagged or removed. Please consider potential impacts to your applications if you have routinely ingested VIIRS near real time
The near real time ACSPO Global SST from MODIS Aqua and Terra processing has been restored and will backfill recent missing days.
CoastWatch has a service outage of the near real time ACSPO Global SST from MODIS Aqua and Terra. We are investigating the problem and will work to restore service as soon as possible. If you need an alternative for your polar-orbiting, SST needs, try ACSPO VIIRS SST.
After more than 11 years in orbit and well beyond its three- to five-year mission baseline, the Ocean Surface Topography Mission (OSTM) on Jason-2 will permanently cease acquisition of scientific data at 06:48 UTC on 1 October 2019 due to aging-related issues onboard the spacecraft. Approximately three hours later, the final pass 147 for science cycle 644 will be produced as an OGDR product and disseminated to operational users. IGDR production will cease about 2.5 days later, GDR production approximately 2 months later.
New Satellite Data Products have been added to the CoastWatch Website:
Three satellite training courses taught by NOAA CoastWatch Nodes are open for sign up:
In situ ocean color database (Beta) GUI Search Tool - released for public access
NOAA CoastWatch THREDDS and FTP servers will undergo maintenance on Tuesday May 28, 2019 at 1100 EDT (1500UTC) [changed from 0800 EDT (1200 UTC)]. Services and data in NetCDF/HDF formats may be unavailable for up to 2 hours. See the News section on the CoastWatch website for updates regarding this planned maintenance event. The following URLs will be affected:
The night-time Blended SST product is currently distributed in two NetCDF variants. The legacy NetCDF Blended product (generated from HDF) will be discontinued in July 2019. These products have the following naming convention and a filesize of ~106MB:
[where YYYY=Year, and JJJ=Day of Year]
A new release of the CoastWatch software is available. Changes include using Java OpenSDK11.0 and performance improvements to cwregister, cwmath, and cwcomposite. Accuracy improvements were made to mapping data with terrain-corrected locations to reduce mapping errors over land. See the CoastWatch Utilities page for more details and access to the new release.
The operational production of the Global Area Coverage (GAC; 4km/nadir) ACSPO SST data from AVHRR instruments aboard NOAA-18/19, and Metop-A/B will be discontinued on or after June 2, 2019. From that point on, ACSPO SSTs will continue to be available from three Full Resolution Area Coverage (FRAC; ~1km/nadir) mid-morning ("AM") Metop-A, -B and -C, and from two VIIRSs (~750m/nadir) onboard afternoon ("PM") NPP and NOAA-20. ACSPO SST from all historical AVHRR/2 and /3 GAC records will only be available in a reprocessing mode, as a part of ACSPO AVHRR GAC Reanalysis ("RAN") project.
Ocean Color Product and Processing Update:
Ocean Color near real-time is restored and includes the release of VIIRS NOAA-20. Coming in April: A daily global blended VIIRS (SNPP plus NOAA-20) for chlorophyll and downwelling attenuation coefficient (Kd(490)).
As of 13MAR2019, CoastWatch distribution of data and products has been sporadic due to numerous issues. The following products are currently unavailable:
- S-NPP VIIRS Ocean Color Level-2 and Level-3 Regional/Sector/Global products
- Sentinel-3A OLCI Ocean Color Level-3 Regional and Global products
- SAR Wind products.
- S-NPP VIIRS and Aqua MODIS True Color products
The following products were delayed:
The Operational Satellite Oceanography (OSO) Training Day on Monday, 17 June 2019, in association with the OSO Symposium in Washington DC area will cover 3 topics and will allot time for individual guidance:
1) Ocean satellite products available
2) Data discovery, access and tools
3) Example applications
4) Time for individual guidance or assistance.
Participants are encourage to bring their own laptops. No terminals will be provided.
As of 09MAR2019, CoastWatch distribution of S-NPP VIIRS Ocean Color Level-2/-3 data and products has been sporadic. Copernicus mission data distribution was delayed Mar 09 to March 11 2019. Level-3 SST (legacy HDF reginal products) were delayed and being backfilled (Note: https://cw2.espc.nesdis.noaa.gov/data/ hold legacy SST and win

Data Quality UPDATE: Near Real Time VIIRS SNPP Ocean Color products quality issue resolved with data beginning March 2, 2018.
The calibration issue affecting the NOAA/IDPS Sensor Data Record (SDR, i.e., L1B) for VIIRS SNPP and the Near Real Time Ocean Color Environmental Data Record (EDR) has been resolved. Data processed as of March 2, 2018 and onward meet quality standards. Thank you for using NOAA CoastWatch/OceanWatch data.
Data Quality NOTICE: Near Real Time VIIRS SNPP Ocean Color products are severely degraded from 16 February 2018 until further notice.
The S-NPP VIIRS ocean color products produced within NOAA STAR are undergoing a processing change (products produced in near real-time operationally within OSPO will remain unchanged). As a result, beginning February 20, 2018 the following changes are expected:
Users of geo-SST products,
This notice is to inform you and your group that certain legacy geo-SST products will be discontinued or severely impacted with the transition of GOES-13 to GOES-16 on or about November 20, 2017.
The legacy GOES-13 SST products, (gridded, in binary format) were not planned for continuation for GOES-16.
Dear CoastWatch VIIRS Ocean Color User,
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.
