Schreiner Jun Li Cooperative Institute for Meteorological Satellite Studies (CIMSS) GOES-8/12 GOES-N/O/P Position of the boom allows for colder detectors and hence less instrument noise. GOES-N/O/P will have similar instruments to GOES-8-12, but will be on a different spacecraft bus. The new bus will allow improvements both to the navigation and registration, as well as the radiometrics. The Onset Of Hurricane Ivan -- 16 September 2004 0100 UTC 0200 UTC 0300 UTC 0400 UTC 0500 UTC 0600 UTC 0700 UTC 0800 UTC 0900 UTC GOES-10 & -12 Sounder Cloud Top Pressure Coverage Outage during landfall Spring and fall outages will be avoided by onboard batteries. Keep Out Zone outages will be reduced.

The Sounder products derived include: clear-sky radiances; temperature and moisture profiles; Total Precipitable Water vapor (TPW) and layer PW; atmospheric stability indices such as Convective Available Potential Energy (CAPE) and Lifted Index (LI); cloud-top properties; clear-sky water vapor winds via radiance tracking; and, total column ozone (experimental). Imagers products include: retrieved Atmospheric Motion Vectors (AMVs); Quantitative Precipitation Estimates (QPEs); cloud parameters; clear-sky radiances; surface (skin) temperature; and, detection and characterization of fires, volcanic ash, fog, and (experimentally) cloud-top information. These products are used for a number of numerical weather prediction and forecasting applications. The upcoming GOES-N Sounder PLT (Post Launch Test) is an important step in preparing for operational use of the Imager and Sounder for generation of numerous products. The new GOES-N/O/P bus means there will effectively be no eclipse outages, much reduced Keep Out Zone outages, better calibration, and improved navigation and registration. Similar to previous GOES checkouts, there will be a period during which the instruments are run in various routine schedules for validation of radiance measurements, as well as for generation of products from the radiances. These post-launch check-out periods are essential to the subsequent successful operational use of the satellite assets.

Investigate and quantify/characterize the quality of the GOES-N radiance measurements. 2. Investigate and quantify/characterize the quality of the GOES-N navigation and registration. 3. Investigate the utility of nearly continuous rapid scan imager imagery for improving forecasts of severe weather. 4. Generate Level-2 products from radiance measurements and characterize their quality by validating them against similar observations/derived quantities from other observational systems. 5. Archive continuous rapid scan imagery & accompanying ancillary data for select severe weather cases in support of GOES-R risk reduction activities. The GOES-N/O/P instruments will be less noisy. -Lower (colder) patch (detector) temperature due to new boom placement allows a better view for radiating to space. - Patch temperatures may (seasonally) range from ~81 to <~88 K
