       Dear Dr  White

            We have reviewed the legislation, policies, procedures and
       practices associated with (1) the operation of geomagnetic obser-
       vatories, (2) the analysis of geomagnetic data, and (3) the
       preparation of geomagnetic information for dissemination to users.
       The review was performed primarily at NOAA headquarters in Rockville,
       Maryland.  A significant portion of the review was performed prior
       to internal reorganiations  which affected the geomagnetism program.
       We did not examine NOAA's basic research activities relating to
       geomagnetism.

            In the mid-1960's NOAA increased its number of permanent
       geomagnetic observatories from 10 to 14 and established a number
       of temporary observatories to conduct activities in 1964 and 1965 --
       the International Quiet Sun Years.  This expansion of the geomagnetic
       observatory network and subsequent reductions in staff assigned to
       analyze geomagnetic data has adversely affected the balance between
       NOAA's data gathering and its analysis and processing capabilities.

            NOAA officials  stated that prior to the personnel reductions,
       which took place between the end of fiscal year  1967 to the end of
       fiscal year  1971, there was sufficient staff to perform the various
       duties to insure  the production of timely and accurate data. The
       personnel reductions necessitated the gradual introduction of modi-
       fied processing procedures which did not provide  the degree of
       accuracy that  formerly existed. Furthermore,  formal standards for
       data quality do not  exist.

             While the users of geomagnetic data have traditionally relied
        on NDAA's reputation for compiling accurate data, there have been
        instances where users detected errors in the processed data after the
        modified procedures were introduced   Although NOAA officials believe
        that most users were unaffected by the modified procedures, the de-
        cision to modify the procedures was not based on a comprehensive
        evaluation of users' requirements.
