• Remotely Sensed Data
  

• NOAA Tiros-N
  

• w/ AVHRR sensor

• AVHRR Level 1 Data
  

• As the TIROS-N satellite orbits, the Advanced Very High Resolution Radiometer (AVHRR)sensor scans perpendicular to the satellite’s track.

• At regular intervals along a scan line measurementsare gathered to form an instantaneous field of view (IFOV).

• Scan lines are aggregated into Level 1 data sets.

• A single file of Global Area Coverage (GAC) data represents:
  

• ~one full earth orbit.

• ~110 minutes.

• ~40 megabytes.

• ~15,000 scan lines.
