NOAA CoastWatch is excited about the US-European spacecraft Sentinel-6.  The satellite is scheduled to launch on Saturday, November 21, 2020 at 9:17:08 a.m. PST (12:17:08 p.m. EST) . 

NOAA CoastWatch is encouraging our users to participate in this upcoming workshop (and/or the survey) and have their interests heard and documented.  CoastWatch will also participate as a stakeholder.  We are not the host of these activities.

S-NPP and NOAA-20 VIIRS data are unavailable for processing within NESDIS/STAR (data should be available through NESDIS/OSPO).  The issue is being worked and we expect data flow/processing to resume within the next 24 hours.

A new release of the CoastWatch Utilities is available.

Updates:

Data from Aqua MODIS remain unavailable due to a spacecraft recorder issue.  Please contact the CoastWatch helpdesk (coastwatch.info@noaa.gov) for assistance in selecting alternative data/products.  We will continue to provide updates on this issue.  

East Coast Node has cancelled their 3-day satellite data training course originally scheduled for 23-25 June in Charleston, SC.

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 (coastwatch.info@noaa.gov) 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 coastwatch.info@noaa.gov.

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. 

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.

A new release of the CW Utilities is available.  Version 3.5.1 (build 762) includes:

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.

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:

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.

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.
