It is our duty to proceed from what is near to what is distant, from what is known to that which is less known, to gather the traditions from those who have reported them, to correct them as much as possible and to leave the rest as it is .... Abu'l-Rayhan Muhamad al-Biruni 973-1050

organizational issues in the conduct of civil earth observations programs. Following the body of the report is a series of appendixes: after a list of acronyms and abbreviations and collected short biographies of CES members, six brief tutorials discuss several scientific topics important to the science and applications of earth observations.

, and numerous foreign satellites some wholly foreign owned, others carrying NOAA or NASA instruments in cooperative ventures. The Mission to Planet Earth began as a scientific initiative called Global Habitability, which had its origins in the research and operational earth observations missions of the 1960s and 1970s.

As structured, the USGCRP will also not generate some other data of substantial value to the earth applications community, such as systematic regional and global topography, digital elevation maps, and magnetic and gravitational fields. The active microwave oceanographic and cryospheric measurements for the USGCRP (altimetry, scatterometry, and synthetic aperture radar, or SAR)

Similarly, as noted in the preceding section on the USGCRP with regard to research, no plans exist for the exploitation of space-based imagery in the preparation of topographic maps, digital elevation models, global vegetation inventones, mineral and soil surveys, or updated standard maps. Such products are among the greatest benefits to be derived from the nation's investment in its space program.

The program should not be detrimentally driven by the pursuit of still another technological objective. Furthermore, the CES sees no pressing need within the domain of civil earth observations to fly satellites as a management demonstration simply to prove that small, modestly capable satellites can be launched quickly.

, which addressed the integration of asynchronous, irregularly distributed measurements of varying quality and character. NASA also convened a special climate modeling workshop whose final report provided a broad survey of the challenges and requirements alluded to above (Unninayar and Bergman, 1993~.

THE ORGANIZATION OF CIVIL EARTH OBSERVATIONS PROGRAMS As noted above, the United States is funding a variety of experimental and operational earth observations programs. They include EOS, Earth Probes, NOAA's polar-orbiting and geostationary operational satellites, Landsat, and the DMSP.
