Preliminary Noise Estimates for Infrared Data from the GOES-13 Imager

This article presents preliminary noise estimates for the GOES-13 Imager, comparing them to values for GOES-12 and highlighting the noise improvements. Tables show noise estimates in radiance and temperature units, based on structure analysis and standard deviation calculations.

  1. Preliminary Noise Estimates for Infrared Data from the GOES-13 Imager Don Hillger NOAA/NESDIS/StAR/RAMMB (Don.Hillger@noaa.gov) Tim Schmit NOAA/NESDIS/StAR/ASPB (Tim.Schmit@noaa.gov) July 2006

  2. Table 1a: Preliminary noise estimates (in radiance units) for the GOES-13 Imager for 20 July 2006 at 1800 UTC compared to preliminary and 5th-year noise levels for GOES-12. From structure analysis on 22,500 space-view pixels.

  3. Table 1b: Preliminary noise estimates (in radiance units) for the GOES-13 Imager for 20 July 2006 at 1800 UTC compared to recent values for GOES-12. (For comparing to Table 1a. From standard deviation calculations based on approximately 10,000 space-view pixels.)

  4. Table 2: GOES-13 Imager noise estimates (in 10-bit GVAR counts and temperature units) compared to GOES-12. From structure analysis on 22,500 space-view pixels.

  5. Table 3: Summary of the noise estimates (in temperature units) for GOES-8 through GOES-13 Imager bands. The specification (SPEC) noise levels are also listed.

  6. Preliminary GOES-13 Imager noise improvements over GOES-12 GOES-13 imager shows a factor of up to 3 times less noise
