IHOP_2002 Satellite: POES NOAA AVHRR Imagery [JOSS]

1.0	General Information 

The National Oceanic and Atmospheric Administration (NOAA) Polar 
Orbiting Environmental Satellites (POES) Advanced Very High Resolution 
(AVHRR) 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/). 
Images from four channels of the AVHRR aboard NOAA 14, 15 and 16 are 
included, all at a 1km resolution:
  Channel 1: (visible; 0.58-0.68 um) 
  Channel 2: (near-IR; .725-1.0 um) 
  Channel 3: (near-IR; 1.58-1.64 um) 
  Channel 4: (thermal-IR; 10.3-11.3 um) 

The products cover the period from May 12, 2002 through June 26, 2002 
and cover the IHOP_2002 sector (32-42N and 90-105W).  By nature of the 
Polar Orbiting Satellite system the observation times of each satellite 
vary from day to day. In general, at least two scans were performed of 
the IHOP_2002 region per day and are included in this dataset.

3.0  Product Information

UCAR/JOSS obtained the Advanced Very High Resolution (AVHRR) data 
from the portable SeaSpace Terrascan receiver system and developed 
sectors of the IHOP_2002 region for the time of interest. This 
dataset consists of horizon to horizon scans at 1-km resolution 
from the visible channel, two near-IR channels, and one of the 
thermal-IR channels of the AVHRR instrument.  Images from 
NOAA 14, 15 and 16 are included.  All images are in JPEG format.

4.0 Quality Control Procedures

UCAR/JOSS conducted no quality checks on these data.

5.0  File Naming Convention

The file names are structured as follows:

  S#    is the satellite number
  YYYY  is the four-digit year of the observation
  MM    is the month of the observation
  DD    is the day of the observation
  mm    is the minute of the observation
  hh    is the hour of the observation
  01km  is the resolution
  ch#   is the channel of the AVHRR
  NNNNN is the name of the channel (vis, near-IR or thermal-IR)
