    instrument on GOES R will actually be able to provide images as frequently as every 30 seconds over special regions of interest such as tropical cyclones or severe thunderstorms A sequence of three AWIPS images of 1 km resolution MODIS and POES AVHRR IR data below displayed intricate cloud top structures and very cold cloud top IR brightness temperatures as cold as 90ºC darker violet color enhancement on the 14 23 UTC MODIS image and the 20 21 UTC POES AVHRR image MODIS 11 0 µm and POES AVHRR 10 8 µm IR images For the three individual 1 km resolution MODIS and POES AVHRR IR images above comparisons with the corresponding 4 km resolution GOES 13 IR images are shown below There are slight time differences between the MODIS AVHRR IR and the GOES 13 IR images but the majority of the northwestward shift in the location of features on the GOES images is due to parallax Even though the spatial resolution of the IR channels on the ABI instrument on GOES R will be 2 km these 1 km resolution comparisons still serve to demonstrate that improved spatial resolution should allow better detection of such detailed cloud top structures and cold cloud top IR brightness temperatures associated with tropical cyclones 08 09 UTC MODIS 11 0 µm IR and 08 15 UTC GOES 13 10 7 µm IR images 14 23 UTC POES AVHRR 10 8 µm IR image and 14 32 UTC GOES 13 10 7 µm IR image 20 21 UTC POES AVHRR 10 8 µm IR image and 20 30 UTC GOES 13 10 7 µm IR image Posted in AVHRR GOES 13 GOES R MODIS POES Tropical cyclones No Comments 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 July 2011 M T W T F S S Jun Aug 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Categories Air quality Antarctic Arctic AVHRR Aviation AWIPS II Calibration Anomalies Cloud Top Cooling Convective Initiation Fire detection Fog detection General interpretation GOES sounder GOES 10 GOES 11 GOES 12 GOES 13 GOES 14 GOES 15 GOES R Google Earth Heavy rain flooding Historical Hydrology Lightning Marine weather McIDAS V Meteosat MODIS MTSAT Other Satellites POES Red Green Blue RGB images Satellite winds Severe convection Suomi NPP Synthetic satellite imagery Training Tropical cyclones VIIRS Volcanic activity Web Map Server What the heck is this Winter weather Other blogs of interest AccuWeather Blogs CIMSS GOES Gallery CIMSS TPARC Support CIRA GOES R Proving Ground Blog EUMETSAT Image Gallery Geographic Information Network of Alaska GOES R and JPSS National Centers Perspective GOES R Fog Product Examples GOES R Hazardous Weather Testbed METSUL blog NOAA NESDIS Operational Significant Event Imagery NSSTC Collaborative Weather
