\"GOES<\/a>

GOES 15\/GOES 13 Sounder loop<\/p><\/div>\n

The earth-viewing instruments on the GOES-15 spacecraft, which is above 90 W longitude, were turned on July 25th, and will be sending Imager and Sounder data for the next two weeks. Satellites in storage are periodically awakened to test functionality. GOES-West, currently GOES-11, will be retired at the end of the year and GOES-15 is a candidate to replace that Geostationary Satellite at 135 W Longitude.<\/p>\n

The above loop shows Sounder data from GOES-15 and GOES-13, both remapped to the same projection, for 1746 UTC on July 27th. Note that the most bands of the Sounder imagery from GOES-15 shows cleaner signals; colder detectors onboard GOES-15 (because GOES-15 has a different configuration than GOES-13) mean that the same signal has less noise.<\/p>\n

Visible imagery from GOES-15<\/A> and GOES-13<\/a> gives similar views of the developing tropical system off the coast of Yucatan, in part because the satellites are only separated by 15 degrees of longitude (GOES-13 sits on the Equator at 75 degrees West Longitude)<\/p>\n

GOES-15 imager data differs from GOES-11. Whereas GOES-11<\/a> has a 12.0 micrometer channel, which is useful for observations of dust and ash (when used in conjunction with the 10.7 micrometer channel), GOES-15<\/a> has a 13.3 micron channel, which data are useful for cloud-top properties.<\/p>\n

\"GOES<\/a>

GOES 15\/GOES 13 Imager Water Vapor loop<\/p><\/div>\n

The GOES-15 Imager water vapor channel has 4-km resolution versus 8-km resolution on GOES-11. In the loop above, note the better depiction of gradients (despite the vastly different view angles) and the better depiction of the mid-level vortex at the southwest edge of the image.<\/p>\n

Another comparison of 8-km resolution GOES-11 6.7 \u00c2\u00b5m water vapor images with corresponding 4-km resolution GOES-15 6.5 \u00c2\u00b5m water vapor images can be seen below, viewing a lobe of middle-tropospheric vorticity that was moving southeastward over Nunavut, Canada (GOES water vapor image with an overlay of GFS 500 hPa vorticity<\/a><\/strong>). Again, the satellite viewing angles are different, but the features and gradients (even at the high latitude of 65 degrees North) <\/em> are much clearer on the GOES-15 water vapor images.<\/p>\n
