LATEST NEWS

Planned discontinuation of NOAA-18 and NOAA-19 AVHRR SST products

Announcing the planned discontinuation of NOAA-18 and NOAA-19 AVHRR SST products from NOAA CoastWatch:

Due to the availability of higher quality data,  our operational partners will be discontinuing the processing of regional sea surface temperature products from AVHRR aboard NOAA-18 and NOAA-19 in December, 2020.  Products will continue to be provided from Metop-A and  Metop-B AVHRR instruments and S-NPP and NOAA-20 VIIRS instruments. 

Global, multi-sensor, gap-filled, science quality chlorophyll is on the Data Portal

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

Information technology issues affecting CoastWatch Products and Services

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 (coastwatch.info@noaa.gov) as there may be secondary URLs to access data products. 

Some of the more prominent known issues include:

Sentinel -3B is back at CoastWatch / Possible delays in Sentinel-3B CoastWatch data products

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. 

Training Course Updates: Charleston SC and San Juan PR

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.

Impacts of Product Outage/Anomaly: VIIRS SDR reflective solar bands (RSB) 16 & 17 January 2020

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

Jason-2 will permanently cease acquisitions on 1 Oct 2019

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.

Scheduled service interruption 28MAY2019 - update

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:

 

Release of CoastWatch CDAT and Utilities version 3.5.0

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.

NOAA discontinues operational AVHRR GAC SST Products

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.

VIIRS Quality Issue Resolved

Data Quality UPDATE: Near Real Time VIIRS SNPP Ocean Color products quality issue resolved with data beginning March 2, 2018.

Dear Users,

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.

Service Announcement

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.

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.
