AVHRR products from both NOAA-18 and NOAA-19 spacecraft are showing significant navigation shifts. As this issue is investigated and depending on application, these products should be used with caution. Products exhibiting the issue are those produced in the 'legacy' CoastWatch HDF format in both Level-2 Swath and Level-3 mapped products. Filenames will contain 'n18' or 'n19', such as: 2020_175_1150_n19_wi.hdf or 2020_176_0959_n19_er.hdf. For alternative SST products for your consideration, please see
The global, multi-sensor, near real time DINEOF gap-filled, chlorophyll has been relased, View and access data through the Data Portal or directly download data from the services linked from the satellite data product page under the "data access" tab.
Processing systems are undergoing maintenance 18-22 MAY 2020. This may adversely impact product processing and data distribution. It is anticipated delays will not exceed 72 hours and will vary by product. All products may be affected.
The global, multi-sensor, gap-filled (i.e., DINEOF), science quality chlorophyll is now on the CoastWatch Data Portal. This URL link will open the Data Portal with this gap-filled product in the scene. Reminder that science quality ocean color data are available on a ~2-week delay, so use the calendar to view
Unforeseen issues have arisen affecting our website links and behind the scenes product processing. Please bear with us as products and services are restored. Should you have immediate needs, please email our help-desk (email@example.com) as there may be secondary URLs to access data products.
Some of the more prominent known issues include:
Due to an IT issue, the CoastWatch East Coast Node website is temporarily inaccessible. We expect services to be restored soon. If you have immediate data requirements, please contact firstname.lastname@example.org.
Sentinel 3B products are back online at CoastWatch.
Planned processing changes are scheduled for Thursday January 30, 2020. There may be a delay in the processing and distribution of CoastWatch Level-2 (RGB) and Level 3 (mapped) products. These changes will not affect data products nor data access pathway. Products delivery times should return to normal by February 1, 2020.
Level-2 data passthrough from EUMETSAT will not be impacted.
East Coast Node has announced details for their 3-day training course 23-25 June in Charleston, SC
Are you interested in using oceanographic satellite data in your work but don't know where to start? The NOAA CoastWatch East Coast Regional Node will offer a three-day course, June 23-25, 2020, at the Hollings Marine Laboratory in Charleston, SC, where participants will learn about environmental satellite data and how to easily obtain it. Participants also gain hands on experience working with the data of interest to them.
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.

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.
