INFORMATION REGARDING THE GOES-8, GOES-9, and GMS-5 SATELLITE IMAGES FOR THE 1996 PEM-TROPICS A MISSION ==================================================================== The 18 GIF images listed in this directory were produced for and featured in the manuscript for the first PEM-Tropics Special Section titled 'A Meteorological Overview of the PEM-Tropics Experiment' by Fuelberg et. al.. McIDAS software was used to display the GMS-5, GOES-8, and GOES-9 2-km visible and 4-km infrared satellite imagery and save them in GIF format. Please state the following acknowledgement if one of the GMS-5 images is used in a publication: "Satellite image/s processed by the Bureau of Meteorology, originally obtained from the Geostationary Meteorological Satellite (GMS-5) of the Japan Meteorological Agency" FILE NAMING PROCEDURE --------------------- Naming procedure for the satellite images is as follows: NoAJdWd_Tm.GIF as in the following example: 20P269VIS_21Z.GIF where: "No" = Flight number, corresponds to aircraft "A" "No" = '20' in above example "A" = research aircraft, so that 'D' = DC-8 'P' = P3-B "A" = 'P' in above example "Jd" = julian day of the year "Jd" = '269' in above example "Wd" = window or channel used GOES8/GOES9 'IR' = infrared channel or 10.7 microns, band #4 'VIS' = visible channel or 0.65 microns, band #1 GMS5 'IR' = infrared channel or 11.0 microns, band #2 'VIS' = visible channel or 0.63 microns, band #1 "Wd" = 'VIS' in above example "Tm" = time in UTC, specified as 'Z' "Tm" = '21Z' in above example McIDAS INFORMATION BAR ---------------------- When viewed, each image has an information bar at the bottom of the image in the form of: POS SATSEN Bd Dy Mn YrJdy HhMmSs Xline Yline RESL as in the following example taken from file '7P237VIS_21Z.GIF': 0002 G-9 IMG 01 24 AUG 96237 210000 02896 04015 15.00 where: "POS" = frame number {reader may disregard} "POS" = '0002' in above example "SATSEN" = satellite sensor used, so that G-9 IMG = GOES-9 G-8 IMG = GOES-8 GMS-5 = GMS-5 "SATSEN" = 'G-9 IMG' in above example "Bd" = band or channel used, so that GOES8/GOES9 '04' = infrared channel or 10.7 microns '01' = visible channel or 0.65 microns GMS5 '02' = infrared channel or 11.0 microns '01' = visible channel or 0.63 microns "Bd" = '01' in above example "Dy" = day of month "Dy" = '24' in above example "Mn" = month of year "Mn" = 'AUG' in above example "YrJdy" = combination of year and julian day of the year, so that "Yr" = year "Jdy" = julian day "YrJdy" = '96237' in above example, where "Yr" = '96', meaning year 1996 "Jdy" = '237', meaning 237th day of year "HhMmSs" = time (UTC) in Hours, Minutes, Seconds "HhMmSs" = '210000' in above example, meaning 21 hours, 00 minutes, and 00 seconds UTC "Xline" = number of lines/elements used in X-direction {reader may disregard} "Xline" = '02896' in above example "Yline" = number of lines/elements used in Y-direction {reader may disregard} "Yline" = '04015' in above example "RESL" = resolution of image in kilometers "RESL" = '15.00' in above example, meaning 15 kilometer resolution IMAGE PROJECTION ---------------- A Mercator projection was used on the images to remove the curvature effects of the round earth in the full-disk image. Continental boundaries are highlighted by a solid white line. Latitude and longitude lines are highlighted by a dashed white line. FLIGHT TRACKS ------------- The flight tracks were produced by plotting the aircraft latitude/ longitude positions from start to finish at 5-minute intervals. On most of the images, the flight tracks "doubled-up" on themselves. To help make the flight tracks less confusing, the color YELLOW was used for the beginning leg and RED for the ending leg of the flight. The following table shows the times (UTC) during the flight where either YELLOW or RED was used.

Latitude labels start at the first horizontal dashed white line at the top of the image and continue downwards to the bottom of the image. Longitude labels start at the first vertical dashed white line on the left side of the image and continue from left to right across the image.
