There are several products available in this dataset.

• Wind direction and speed derived by JPL from the scatterometer instrument aboard the ERS-1 and ERS-2 satellites. These along swath orbit data are online at NCAR. However, due to restrictions place on the data usage, by the European Space Agency (ESA), data users must first receive permission to use this dataset. Questions concerning permission should be directed to:
• The above ERS products were archived in the 1990's and are quite old versions. Better versions are available through European KNMI/ESA sources.
• 1-degree by 1-degree, 80S to 80N, monthly mean grids for ERS1 (1991.01-1996.05) and ERS2 (1996.04-1999.12). These data were obtained directly from CERSAT, IFREMER, France. Extant variables include wind speed, U and V wind components, stresses, divergence and curl.
