Global Monthly AVHRR Climatology Over Land (1985 - 1994) and Pathfinder Climate Data (1987 - 1988) CD-ROM Products

Type of change: Discontinue two product web pages hosted at NCEI-CO.Description:

The National Centers for Environmental Information, Boulder, Colorado location (NCEI-CO) host two legacy products online originally created for CD-ROMs back in the 1990s. One product is the Global Monthly AVHRR (Advanced Very High Resolution Radiometer) Climatology Over Land CD-ROM, (spanning 1985 - 1994) and NOAA/NASA Pathfinder Climate Data CD-ROM (spanning 1987 - 1988). Both products utilize raw data that exist at either the NOAA or NASA archives, and were created under the auspices of an Ecosystems Division that no longer exists within the organization.

The products utilize software that is no longer supported or maintained, the web pages contain obsolete links and references to individuals and resources that are no longer associated with the organization, and in many cases, contain data formats that have become outdated. The state of both products have lost their utility over time (last update made in 1997-98) as technology has evolved, support personnel have moved on and the priorities of organization have changed.

Metadata Enterprise Resource Management Aid (MERMAid).

Last Updated: 01/10/2015

Type of change: MERMAid Deactivation

This message is to inform our users that NESDIS/NCEI is considering discontinuing the Metadata Enterprise Resource Management Aid (MERMAid) product. MERMAid is a secure, online Web-based application that allows users to develop metadata records in compliance with the Federal Geographic Data Committee Content Standard for Digital Geospatial Metadata, to organize these metadata records any way they see fit (i.e., by project, data type, personnel, etc.), and to publish these records to catalogs for public discovery and data access. While MERMAid has proven very beneficial over many years, it does not meet NOAA’s directive to use ISO to document NOAA’s environmental data and information. Moreover, it is built on a software base that is no longer supported within NCEI. If MERMAid is deactivated, current users will need to find alternate sources for the editing, validation and publication of their standard CSDGM and related profile metadata. In addition, any published metadata available on the National Centers for Environmental Information’s WAF from existing accounts will be unavailable as of December 31, 2015. NCEI will export existing metadata records upon request.

NOAA Observing Systems Architecture (NOSA)

Last Updated: 04/30/14

Type of change: Discontinue website hosted at NGDC.

During 2002 Vice Admiral Conrad C. Lautenbacher, Jr., USN (Ret.) called for a fundamental review of NOAA's strengths and opportunities for improvement. A Program Review Team reviewed and debated issues and developed suggestions for building a better NOAA. These suggestions led to a recommendation to have a centralized planning approach for integrating NOAA observing systems and indicated a clear need for a NOAA-wide observing system architecture. NOAA responded by creating the NOAA Observing System Architecture (NOSA) Action Group, which led the charge on having a website and backend database created to store information about NOAA's observing system architecture. The goals of this IT project were: design observing systems that support NOAA's mission and provide maximum value, avoid duplication of existing systems, and operate efficiently and in a cost-effective manner. NOSA includes: NOAA's observing systems (and others) required to support NOAA's mission, The relationship among observing systems including how they contribute to support NOAA's mission and associated observing requirements, and the guidelines governing the design of a target architecture and the evolution toward this target architecture. NGDC no longer receives funding for maintaining information stored in the underlying relational database, and some of the search tools are no longer maintained to serve the initial purpose of the website. The contents of the database will be transferred to NOAA's Technology, Planning, and Integration for Observation (TPIO) Office.

The processing of MODIS/Aqua Ehux bloom and calcite products

Last Updated: 04/21/14

Type of change: Termination of the processing of MODIS/Aqua Ehux bloom and calcite products

The generation of global MODIS/Aqua Emiliania huxleyi bloom and calcite concentration products will be terminated on 22 May 2014 unless a NOAA operational user for either of these products is identified prior to this date. Though the E. huxleyi bloom and calcite products provide valuable information to assist in monitoring the response of the marine ecosystem to ocean acidification and climate change, we have not identified any NOAA operational users that will use either of these two products. As a result, the NOAA Satellite Product and Services Review Board has recommended that the Office of Satellite and Products Operations terminate the processing of these two products until NOAA operational users for these products are identified. The MODIS/Aqua E. huxleyi bloom and calcite products have been generated and distributed to the user community since October 2012. They are monitored at http://www.ospo.noaa.gov/Products/ocean/color/index.html , and are accessible in ftp://cw-okeanos.noaa.gov/pub/data1/EHUX_data_experimental/. Note that the products have been reduced from 24 regions (global coverage) to six regions since 6 March 2014.

Each instrument has its own strengths and weaknesses, depending on the sensor type, platform, orbit, etc. The production of an accurate SST depends on merging the data from these sources and accounting for the differing measurement methods and accuracies while maintaining as much of the information in the observations as possible to capture the best of each sensor.The product to be discontinued is a daily SST analysis (operational June 2008) that combines Geostationary (GOES-E/W, MT-SAT and Meteosat) SST and POES and Metop (AVHRR) SSTs into a single high-resolution (0.1°x0.1°) product.

This original resolution was chosen to approximately match the Nyquist sampling criterion for the mid-latitude Rossby radius (~20 km) to ensure the preservation of mesoscale oceanographic features such as eddies and frontal meanders. The methodology employs a rigorous multi-scale optimal interpolation which approximates the Kalman filter, together with a data-adaptive correlation length scale to ensure the balance between detail preservation and noise reduction. The analysis has proven a significant success, even when compared to other products which purport to be of similar or higher resolution.The 11km blended SST product can be replaced with the higher resolution product which uses the same multi-scale optimum interpolation technique cited above. The replacement product is at 5km (1/20 degree) grid spacing.

Global Ecosystems Database

Last Updated: 01/19/12

Type of change: Discontinue archival support and data distribution at NGDC.

The Global Ecosystems Database (GED) project began in 1990 as an Interagency project between the National Geophysical Data Center (NGDC) of the U.S. National Oceanic and Atmospheric Administration (NOAA), and the U.S. Environmental Protection Agency's (EPA) Environmental Research Laboratory in Corvallis, Oregon (ERL-C). The primary objective of the project was to produce a spatially integrated database (including observational time sequences and model simulation outputs) with high quality metadata for characterization and modeling support within the US Global Change Research Program (USGCRP).

Datasets were selected for publication to meet research priorities established by the EPA/ERL-C and to expand the use of datasets of potential value to the modeling and applied research community. Following prototype development, the first publicly released volume of the database was GED "Disk A" (September 1992). In 1993 datasets for Disk B were distributed for review. The final version of disk B, published in 1997 completed the review, update, and publication process with new or revised versions plus several important additional datasets contributed through 1997. The current online GED combines the datasets from Disk A and Disk B, the former has been updated from its original version to meet the same metadata standards as Disk B.NGDC no longer has data stewardship support or a mission focus to continue supporting this data set.

The lead author, Dr. John J. Kineman, Senior Research Scientist at the University of Colorado ( http://cires.colorado.edu/science/groups/wessman/people/kineman/ ) will maintain a complete set of the data. Future possibilities include a data transfer to the National Climatic Data Center.

NESDIS GOES 5x5 Sounding BUFR Retrievals

Last Updated: 10/20/11

Type of change: Replacement / Retirement

The replacement GOES 1x1Sounding BUFR Retrievals product will begin transmission to the user on November 22nd at 15Z UTC. The GOES 5x5 Sounding Retrievals are vertical atmospheric temperature or moisture profiles derived from radiances measurements. The radiance measurements are from a variety of instruments flown on NESDIS’ current GOES EAST/WEST weather satellites. The GOES 5x5 bufr sounding retrievals are being generated twice per hour per satellite. All of the retrievals are placed into BUFR format to be utilized by users. The profiles are averaged over a 5x5 pixel area giving a resolution of 50 km. The new and improved 1x1 bufr sounding retrievals that have replaced the 5x5 are at 10 km resolution and give profile information for each pixel. This improvement equates to about .4 mm for Precipitable Water (PW) and about .3o - .5o K for temperature. The increase in the amount of data being produced and transmitted to the users per hour, allows for more overall detailed analytical information.
