What does this data set describe?

NOAA Coral Reef Watch 25km Ocean Acidification Product Suite (OAPS) for January 1988 to the present covering the Greater Caribbean Region
The NOAA Coral Reef Watch Experimental Ocean Acidification Product Suite (OAPS) offers an important synthesis of satellite and modeled environmental datasets to provide a synoptic estimate of sea surface carbonate chemistry in the Greater Caribbean Region. This tool compliments ongoing geochemical surveys and monitoring efforts in the region by providing estimates of changing ocean chemistry on a broader spatial and temporal scale than shipboard observations alone can permit. The maps presented here are monthly averages of daily estimates derived according to Gledhill et al., 2008. Near-real-time estimates are modeled from daily fields of NOAA Optimum Interpolation Advanced Very High Resolution Radiometer - Advanced Microwave Scanning Radiometer (AVHRR-AMSRE) SST, Hybrid Coordinate Ocean Model + Navey Coupled Ocean Data Assimilation (HYCOM + NCODA) modeled sea surface salinity (SSS), NOAA National Centers for Environmental Predication (NCEP) sea-level pressure (SLP), and estimates of atmospheric CO2 derived from the NOAA Earth System Research Laboratory GLOBALVIEW-CO2 reference marine boundary layer (MBL.

Why was the data set created?

The global oceans are the largest natural reservoir for excess carbon dioxide in the atmosphere, absorbing approximately one third of that attributed to human activities each year. As a result, dissolved CO2 in the surface ocean will likely double over its pre-industrial value by the middle of this century, representing perhaps the most dramatic change in ocean chemistry in over 20 million years. In coming decades, ocean acidification could affect some of the most fundamental biological and geochemical processes of the sea. The purpose of this dataset is to contribute to the understanding of changing ocean chemistry and its relationship to climate.

Access_Constraints: none
These experimental data are made freely available to the public and the scientific community in the belief that their wide dissemination will lead to greater understanding and new scientific insights. However, the availability and distribution of these data does not constitute publication of the data. NOAA relies on the ethics and integrity of the user to ensure that NOAA Coral Reef Watch and AOML receive fair credit for their work. If the data are obtained for potential use in a publication or presentation, the data producer should be informed at the outset of the nature of this work. If the OAPS data are essential to the work, or if an important result or conclusion depends on the data, co-authorship may be appropriate. This should be discussed at an early stage in the work. Manuscripts using the OAPS data should be sent to the producer for review before they are submitted for publication so the producer can ensure that the quality and limitations of the data are accurately represented. The methodology and science algorithms used to produce this data set are documented in the following publication: Gledhill, D.K., R. Wanninkhof, F.J. Millero and M. Eakin (2008).
