IHOP_2002 Satellite:  GOES-8 Imagery [JOSS] 


1.0  General Information


The GOES-8 Imagery is one of several satellite products collected 
as part of the International H20 Project (IHOP_2002) field catalog operated 
by the University Corporation for Atmospheric Research/Joint Office for 
Science Support (UCAR/JOSS; http://www.joss.ucar.edu/ihop/catalog/).
UCAR/JOSS utilized its SeaSpace system to retrieve data from the Geostationary 
Operational Environmental Satellite 8 (GOES-8) and developed sectors over the 
IHOP_2002 region.  This data set consists of the sectored 1-km imagery from 
Channel 1 and sectored 4-km imagery from Channels 1-5 of the GOES-8 satellite.  
  Channel 1: (visible; 0.65um) 
  Channel 2: (shortwave; 3.90um) 
  Channel 3: (Water Vapor; 6.75um) 
  Channel 4: (longwave infrared; 10.70um) 
  Channel 5: (split-window; 12.0um) 

The products cover the period from 1 - 21 June 2002 and cover the IHOP_2002 sector 
(32-42N and 90-105W).  The products are typically available every 15 minutes, but 
rapid scan imagery are also often available (most often during the afternoon and 
evening hours).  All images are in JPEG format.

UCAR/JOSS conducted no quality checks on these data.


5.0  File Naming Convention


There are two different file naming conventions.  One for the 1KM resolution
images and another for the 4KM resolution images.

1KM:
  ops.goes-8.yyyymmddhhmm.IHOP_1km_ch1_vis.jpg

  Where goes-8 is the satellite used
      yyyy is the four digit year
      mm is the two digit month
      dd is the two digit day
      hh is the hour (UTC)
      mm is the minute
			IHOP_1km_ch1_vis is the name of the product
4KM:
  ops.goes-8.yyyymmddhhmm.conus_4km_ch1_vis.jpg
  ops.goes-8.yyyymmddhhmm.conus_4km_ch2_near-IR.jpg

  ops.goes-8.yyyymmddhhmm.conus_4km_ch4_thermal-IR.jpg
  ops.goes-8.yyyymmddhhmm.conus_4km_ch5_thermal-IR.jpg

  Where goes-8 is the satellite used
      yyyy is the four digit year
      mm is the two digit month
      dd is the two digit day
      hh is the hour (UTC)
      mm is the minute
      conus is the scan sector of the satellite
			The remainder is the channel and name of the product
