The ORNL DAAC announces the release of a data set from the International Satellite Land-Surface Climatology Project (ISLSCP) Initiative II project.
ISLSCP II Air-Sea Carbon Dioxide Gas Exchange . Data set prepared by T. Takahashi, S.C. Sutherland, R.H. Wanninkhof, R.A. Feely, R.F. Weiss, D.W. Chipman, N. Bates, J. Olafsson, C. Sabine, A. Poisson, N. Metzl, B. Tilbrook, Y. Nojiri, and C. Sweeney. This data set contains the calculated net ocean-air carbon dioxide (CO2) flux and sea-air CO2 partial pressure (pCO2) difference. The estimates are based on approximately one million measurements made for the pCO2 in surface waters of the global ocean since the International Geophysical Year, 1956-1959. Only the ocean water pCO2 values measured using direct gas-seawater equilibration methods were used.

The ISLSCP Initiative II data collection is designed to support modeling studies of the global carbon, water and energy cycle. This data collection contains 50 global time series spanning the ten-year period 1986 to 1995 compiled under the guidance of Forrest Hall and colleagues at NASA's Goddard Space Flight Center. The data for Initiative II were acquired from a number of U.S. and international agencies, universities, and institutions, then co-registered to equal-angle grids of one degree, one-half and one-quarter degree resolution and reformatted into a common ASCII format.
The collection includes a variety of remotely sensed data sets ranging from visible to microwave wavelengths. The data sets also include improved topography, surface radiation, near-surface meteorology, precipitation, runoff, soils, and vegetation data sets that can be used in a variety of interdisciplinary research activities. Several data sets to support global carbon and biogeochemical studies are also provided.
The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.
