“…A representation of the goodness of data fit can be obtained by computing rms differences between all data (including any which the analysis system may have rejected as erroneous) and the analyses. I n figure 10, two such temperature representations are shown, one for the month of February 1969 (as calculated by Johnson 1972) A severe test for the SIRS-derived temperatures would be to compute the rms differences of those data from the radiosonde analyses. We call this a severe test since the SIRS data are mrtually independent of the analyses.'…”

“…For example, the original statistical procedure used to obtain temperature information from SIRS A radiances depended heavily on collections of radiosonde temperature and height data from the preceding several days (Smith et al 1970, Hayden 1971. Johnson and McInturff (1970) showed that SIRS 'data generated in this way were sufficiently compatible with radiosonde data to be utilized in constant-pressure analysis during the stratospheric summer period.…”

The usefulness of Nimbus 4 satellite infrared spectrometer (SIRS)-derived temperature and height data for constant-pressure analyses at stratospheric levels is investigated by comparing SIRS data with rawinsonde observations and objective analyses of those data. Results from the various methods of comparison are difficult to interpret since systematic and random errors of observatfons at stratospheric altitudes do not permit the observed data to be used as an unquestioned standard. In addition, conclusions must be qualified by the fact that the SIRS information derived to date has depended in part on analyses of rawinsonde data. The following conclusions were reached from the various comparison studies: (1) SIRS data are useful for constantpressure analyses at stratospheric levels, (2) mean differences between analyzed rawinsonde temperatures and SIRS derivations are'generally less than 3"C, (3) differences are greater during stratospheric warmings, but SIRS data generally indicate the proper trend of the temperature changes, thus adding information about the temperature of the real atmosphere to an analysis, and (4) stratospheric SIRS data after Nov. 5, 1971, can be used with more confidence than those derived before that date.

“…A complete answer is not yet available. Various comparisons have been made of the satellite-derived temperatures and heights with data from radiosondes (e.g., Hayden, 1971;Johnson and Mclnturff, 1970;Gelman and Mclnturff, 1971) and rockets (Miller and Finger, 1972). These studies show that up to about the 30-mb level, there is generally good agreement with the radiosonde data.…”

A review of engineering and research data requirements for altitudes 30-100 km is made, indicating a variety of concrete data applications above 30 km (10 mb). The required data have in large measure been provided from meteorological rocket soundings, of which 18,000 have been taken, at considerable cost, since 1959. Remote vertical soundings based on satellite infrared radiation measurements have been obtained since 1969 with considerable success to an altitude of 25 km (30 mb). From developmental work in progress, it is expected that reliable temperature soundings may be obtained to 40-45 km. A discussion of the overall reliability and utility of the satellite data leads to several conclusions regarding the continuing need for rocket soundings.
