            This webpage has real-time and historical notices regarding the 1B processing. The Pre-Product Processing (PPP) produces the Polar Level 1B orbital products for the instruments on the POES spacecrafts. Instrument data is ingested, calibrated and Earth location data is applied to produce the 1B data set.

      <abstract>
        The Solar Backscatter Ultraviolet Radiometer-2 (SBUV/2) is an operational remote sensor designed to map, on a global scale, total ozone concentrations and the vertical distribution of ozone in the earth&apos;s atmosphere.  The 1b Capture Data Set contains (1) all SBUV/2 sensor data and support data necessary for the derivation of atmospheric ozone and solar flux; (2) instrument in-flight calibration data and housekeeping functions for monitoring post-launch instrument changes; and (3) prelaunch calibration factors, and computed current-day instrument calibration and albedo correction factors to adjust the ozone algorithm for actual instrument performance.
      </abstract>
      <purpose>
        For ozone research users. Knowledge of the temporal and spatial distribution of atmospheric ozone is important since ozone strongly absorbs solar ultraviolet energy and prevents this harmful radiation from reaching the earth&apos;s surface.

      The SBUV/2 instrument can only measure ozone during daylight hours. In addition, there are times when various SBUV/2 instruments are put into special modes of data collection that prevent the retrieval of total and profile ozone.

    <posacc>
      <horizpa>
        <horizpar>
          SBUV/2 data is collected in 32 sec major frames.  In discrete mode, the mode used for retrieval of total and profile ozone, a set of 12 measurements (1 for each discrete wavelength band) is taken every 32 seconds.  Latitude and longitude values are provided in the data record at the beginning and end of each 32 second major frame.        The instrument manufacturer (Ball) data books typically list SBUV/2 pointing errors from laboratory measurements of approximately 0.15 degrees in the X-direction, and 0.05 degrees or less in the Y-direction.  This represents ~2 km or less at the surface.  Uncertainties in satellite orientation and/or timing will add to this value.
        </horizpar>
      </horizpa>
      <vertacc>
        <vertaccr>
          Since SBUV/2 is a nadir-viewing instrument, it provides no inherent information about altitude, and therefore no estimate of vertical accuracy can be made. The vertical resolution is related to the nature of the retrieval algorithm.  It is estimated that vertical resolution is at best about 6 km for a BUV type algorithm.

          Data is processed from the SBUV/2 instrument in near real-time in the Operational Ozone Product System (OOPS). Raw data and ozone products are generated for the archive. Six sources of data are used, the first three being dependent on satellite and instrument operation and therefore continually changing; and the next 3 being relatively fixed sets of reference data, changing only due to new scientific knowledge or to correct errors: 
SBUV/2 Raw TIP data and TOVS meteorological data are each captured about 14 times a day, with typically one orbit&apos;s worth of data being captured and stored.  Once a day, a Daily 1B Data Set is produced containing all available data for the previous calendar day.

          SBUV/2 Orbit Frame
        </enttypl>
        <enttypd>
          Each SBUV/2 orbit begins when the center of the SBUV/2 instrument field of view (FOV) transits the equator on the dark viewing side of the Earth and continues through one satellite revolution about the Earth. Earth location data is used to ascertain equator crossing but is only given for the start time of each TIP major frame&apos;s (32 seconds) worth of data. Thus, the SBUV/2 orbital designation of each TIP major frame&apos;s worth of information is based on the earth location at the start of each major frame.

          Cloud and temperature data from TOVS
        </attrlabl>
        <attrdef>
          The total ozone algorithm requires cloud information primarily to estimate the ozone hidden from the satellite sensor below the clouds. Meteorological data is provided to the SBUV/2 1b Data Set from the TIROS Operational Vertical Sounder (TOVS) carried aboard the same satellite as the SBUV/2 instrument. Meteorological data is collected only when the instrument is in the discrete mode (normal mode for ozone determination), the position mode (rarely if ever used), and wavelength calibration mode. These three modes have in common the same record format, i.e. the discrete data record. As the ancillary data is not time dependent, this data will be written once for each Daily 1b data set. It is not saved for sweep mode data. Cloud and temperature information is only stored if there is a good working HIRS instrument on the same instrument as the SBUV/2.  If not, these fields are missing.

              Cloud top temperatures are provided on a spot by spot basis. The current operational TOVS processing system provides SBUV/2 with cloud data for boxes which are adjacent to nadir. Miniboxes are constructed by selection of the appropriate spots in a box. Cloud top pressures (analogous to cloud top height) are computed for each spot by linear interpolation of the cloud top temperature between adjacent levels in the temperature profile.

            </edomv>
            <edomvd>
              The vertical temperature profiles are given for up to forty specified pressure levels ranging from 1000 mb (or surface level) to 0.1 mb. These profiles represent one &quot;box&quot; in the current operational TOVS processing system (formerly a &quot;box&quot; in the old TOVS processing system). A &quot;minibox&quot; consists of 63 HIRS/2 fields of view (called spots) from 7 HIRS/2 scan lines (a &quot;box&quot; consisted of 9 spots from 3 scan lines). Certain quality checks are made during TOVS processing to assure the reasonableness of the temperature profiles. If any of these checks indicate a bad sounding, the profile is rejected during the SBUV/2 processing and replaced with fill values.

          Contains four sets of values:

            Three sets of prelaunch calibration values are required:  
 	i) Radiance calibrations - count to W/cm3 conversion constants.  
 	ii) Irradiance calibrations - count to W/cm3/sr conversion constants.  
  	iii) Prelaunch diffuser check flux ratios.  

The radiance and irradiance calibrations each consist of 37 constants: one value for the CCR at 3786.2 Angstroms and 12 values for each of the three monochromator gain ranges at the 12 discrete wavelengths. The ratios of the radiance and irradiance calibrations are used in the computation of I/F ratios in the ozone computation. The prelaunch flux ratios will be used to perform the diffuser calibration in the instrument support subsystem. There will be one ratio for each mercury line chosen which is to be specified. The monochromator interrange ratios and albedo correction factors are derived from the previous N (to be specified) day&apos;s instrument outputs for the current day 1b and ozone processing. There are two interrange ratios for the monochromator, one between gain ranges 1 and 2 (IRR21) and one between gain ranges 2 and 3 (IRR32).The albedo corrections account for solar flux and instrument changes and are used to adjust the I/F ratios in the ozone processing; there are 13 values for a day, one for the CCR wavelength (3786.2 Angstroms) and twelve for the monochromator discrete wavelengths.

	Operational dates: February 25, 1985 to November 7, 1988. 
		
NOAA-9 was the second operational satellite in the Advanced TIROS-N series. The spacecraft was rectangular shaped (166&quot; long by 74&quot; high) and powered by a 191&quot; by 94&quot; solar array. The satellite was Earth oriented, three-axis stabilized and weighed approximately 2000 pounds. NOAA-9 was placed in a near circular, (470nm) polar orbit. The APT and HRPT capabilities still exist with this satellite.

        The SBUV/2 is a nadir pointing nonspatial scanning instrument sensitive to radiation in the 160 nm to 400 nm ultraviolet spectrum. The SBUV/2 instruments on the TIROS-N satellites are designed to measure the total ozone in a vertical column beneath the satellite and its distribution with height in the atmosphere. The SBUV/2 contains a scanning double monochromator and a cloud cover radiometer (CCR) designed to measure ultraviolet (UV) spectral intensities. In its primary mode of operation, the monochromator measures solar radiation backscatter by the atmosphere in 12 discrete wavelength bands in the near-UV, ranging from 252.0 to 339.8 nm, each with a bandpass of 1.1 nm. The total-ozone algorithm uses the four longest wavelength bands (312.5, 317.5, 331.1, and 339.8 nm), whereas the profiling algorithm uses the shorter wavelengths. The cloud cover radiometer operates at 379 nm (i.e. outside the ozone absorption band) with a 3.0-nm bandpass and was designed to measure the reflectivity of the surface in the instantaneous field of view (IFOV). The SBUV/2 also makes periodic measurements of the solar flux by deploying a diffuser plate into the field of view (FOV) to reflect sunlight into the instrument. The monochromator and the cloud cover radiometer are mounted so that they look in the nadir direction with coincident nominal FOV&apos;s of 11.3 by 11.3 degrees. As the satellite moves in a Sun-synchronous orbit, the FOV traces 160-km wide paths on the ground. The earth rotates approximately 26 degrees during each orbit. The satellite footprint moves at a speed of about 6 km/sec. In discrete mode a set of 12 measurements, 1 for each discrete wavelength band, is taken every 32 seconds. The order of measurements is 252.0 to 339.8 and the integration time is 1.25 seconds per measurement. For each monochromator measurement there is a cloud cover radiometer measurement.
