N2 - The objective of this article is to publicize the availability of two data reports containing detailed compilations of circulation statistics for the FGGE (First GARP Global Experiment; later renamed the Global Weather Experiment) year, which extends from December 1978 to November 1979. The first report documents the three-dimensional distributions of selected time-averaged, variance and covariance statistics as computed using twice-daily Level III- b analyses produced by GFDL (Geophysical Fluid Dynamics Laboratory). The second report offers a thorough comparison between the GFDL statistics displayed in Report A and the corresponding quantities computed using Level III-b analyses generated by ECMWF (European Centre for Medium-Range Weather Forecasts) during SOP-1 (First Special Observing Period; approximately corresponding to the months of January and February 1979) and SOP-2 (May and June 1979). Daily global maps of the windfield at 200 and 850 mb, geopotential height at 50, 300, and 500 mb, and sea-level pressure have already been compiled by Bjorheim et al. (1981) for the ECMWF analyses, and by Polshay et al (1983) for the GFDL analyses. A list of the statistics incorporated in Reports A and B is given in Sections 2 and 3, respectively. Highlights of differences between the GFDL and ECMWF statistics are presented in Section 4. The discussions in Sections 2-4 are elucidated by figures extracted directly from Reports A and B. -from Author
