CoastWatch Data Portal has been updated with new features and additional datasets

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:

sst_geo-polar-blended_night_5km_YYYYJJJ.nc
[where YYYY=Year, and JJJ=Day of Year]

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 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)).

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.

FIRST INTERNATIONAL OPERATIONAL SATELLITE OCEANOGRAPHY SYMPOSIUM

Open access to the enterprise OceanWatch Monitor (OM) online tool now available (v1.0).

The following NOAA CoastWatch data servers will be removed from service on or about December 15, 2018:

A third day has been added to the agenda of the First International Operational Satellite Oceanography Symposium, now18-20 June 2019 in College Park, MD, convenient to Washington DC [revised flyer].  A training session will be included.

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.
