    VIIRS 3 Comments Noise in the Shortwave GOES 13 Sounder Channels September 19th 2012 Multipanel display of GOES East Sounder Channels The shortwave infrared channels on the GOES 13 sounder have displayed increasing amounts of noise over the past months The multi channel display above shows distinct noise in the channels at 4 57 µm 4 53 µm 4 45 µm and 4 13 µm Animations of the GOES 13 GOES 15 imagery from AWIPS shows that the noise is far more obvious in the GOES 13 channel It is especially noteworthy in the 4 45 µm channel called the 4 5 µm channel in AWIPS but also readily apparent in the 4 13 µm channel called the 4 0 µm channel in AWIPS Data from these noisy channels are used in the computation of derived products The effect of the noise is manifest as small scale noise in the derived fields of total precipitable water for example and the bad data is most noticeable at night because the shortwave data are used to identify cloudy pixels during the day visible imagery identifies cloudy pixels Thus maps of for example lifted index have too many pixels flagged as cloudy at night compared to during the day Also compare the 0600 UTC Total Precipitable Water TPW image to the 1900 UTC image Sounder Cloud Top Pressure From GOES 13 and GOES 14 click image to toggle between images Because the shortwave data are used to identify cloudy pixels night time estimates of cloud top pressure as also impacted as shown above The GOES 13 Sounder derived cloud top pressure includes several regions that are indicated as cloudy because of the noisy shortwave data A similar field derived from GOES 14 sounder data does not include the cloudy pixels Data from 1800 UTC when visible imagery can be used to screen out clear pixels with more efficacy shows less contamination that can be traced to the shortwave fields That is the fields derived from the GOES 13 and GOES 14 Sounder look more similar NESDIS scientists are evaluating how the shortwave bands can be excluded from the GOES 13 Sounder computation to reduce night time noise in the output fields Real time GOES Sounder imagery is available at this link Derived products including Convective Available Potential Energy CAPE TPW Lifted Index and cloud top properties can also be viewed at that link Some imagery in this blog post courtesy of Tim Schmit NOAA NESDIS This plot courtesy of Mat Gunshor CIMSS shows the standard deviation of the difference between observed brightness temperature and forward calculated brightness temperatuers A big jump in noise occurred in late August Posted in Calibration Anomalies GOES 13 GOES 14 GOES 15 No Comments Older Entries Newer Entries Webmaster Follow us on Search for Pages About this site CIMSS Satellite Proving Ground Contact us Mobile users POES AVHRR in AWIPS SatePedia Suomi NPP JPSS Proving Ground VISIT SHyMet Training Topics November 2012 M T W T F S

Spaceflight Meteorology Group reported that GOES imagery was loading into certain MODIS directories The National Control Facility recommended making some changes to the LLL localDataKeys txt file such that the third pipe delimited column of all MODIS entries contains a value 3 for a final processed image and the fifth column contains a value 2 for westConus or 1 for eastConus Run the localization process again restart the satellite decoder and restart the notification server after making the changes Oddities Explained You may notice a stripe of omitted data in the transition area between shallow coastal water and deep offshore water at night There are different MODIS algorithms for cloud masking that are implemented depending on whether the detection is occurring are over land desert coast deep water etc The line in the side image represents the transition from the coast to the deep water algorithm The deep water algorithm employs some tests which include a 3x3 pixel spatial variability test This cannot be applied if there is not a 3x3 pixel deep water scene Ultimately a different set of tests are applied in this transition zone resulting in the stripe denoting the transition area Since cloud detection is different and less complex during the day this stripe should not appear on any daytime passes Kathy Strabala Further Reading The IMAPP MODIS Sea Surface
