Comparisons of GOES-15, GOES-16 and GOES-17
* GOES-17 imagery shown here are preliminary and non-operational *
A 3-panel comparison of Visible images from GOES-15 (GOES-West), GOES-17 and GOES-16 (GOES-East) shown above highlights the dissipation of fog in the Strait of Juan de Fuca during the morning hours on 17 July 2018. The three sets of images are displayed in the native projection of each satellite (with no re-mapping) — GOES-17 was at its post-launch checkout location of 89.5ºW longitude. Images from GOES-16/17 were at 5-minute intervals, while images from GOES-15 were every 5-15 minutes depending on the operational scan schedule of that GOES-West satellite.
A similar 3-satellite comparison shown below focuses on the development of showers and thunderstorms across western Montana, between Missoula KMSO and Butte KBTM. The improved spatial resolution (0.5 km at satellite sub-point for GOES-16/17, vs 1.0 km for GOES-15) and more frequent images allowed small-scale features of the storms to be more easily identified and followed.
One final comparison, shown below, depicts thunderstorms over western Colorado — outflow boundaries south of these storms produced strong surface winds in the Grand Junction area (SPC storm reports).
Yesterday’s peak wind gust of 70 MPH at the @GJAirport set a new record wind speed for the month of July, breaking the old record of 68 MPH set on July 14, 2002! #cowx #climate
