EXAMPLES

Example 1

Perform a radiometric (solar zenith angle) correction of a 2-channel input database, and output the results to the same 2 channels in the same file. The AVHRR calibration/orbital data are stored in segment 3. A report will be printed on screen.

 EASI>FILI="AVHRR.PIX"
 EASI>FILO="AVHRR.PIX"
 EASI>DBIC=1,2
 EASI>DBOC=1,2
 EASI>AVHRRSEG=3
 EASI>TIMEMULT=
 EASI>CTYPE="SOL"
 EASI>REPORT="TERM"
 EASI>RUN AVHRRAD

Example 2

Perform a visible channel calibration of channels 1 and 2. No report will be generated. AVHRRAD will look for a valid AVHRR text segment to use.

 EASI>FILI="AVHRR.PIX"
 EASI>FILO="AVHRR.PIX"
 EASI>DBIC=1,2
 EASI>DBOC=1,2
 EASI>AVHRRSEG=
 EASI>CTYPE="VIS"
 EASI>REPORT="OFF"
 EASI>RUN AVHRRAD

Example 3

Perform a thermal channel calibration of channels 3,4,5. A report will be written to the file, "REP.TXT".

 EASI>FILI="AVHRR.PIX"
 EASI>FILO="AVHRRAD.PIX"
 EASI>DBIC=3,4,5
 EASI>DBOC=1,2,3
 EASI>AVHRRSEG=3
 EASI>CTYPE="THE"
 EASI>REPORT="REP.TXT"
 EASI>RUN AVHRRAD

Example 4

Perform all corrections/calibrations to the input PIX file. The results are written back into the same file.

 EASI>FILI="AVHRR.PIX"
 EASI>FILO=FILI
 EASI>DBIC=1,2,3,4,5
 EASI>DBOC=DBIC
 EASI>AVHRRSEG=
 EASI>CTYPE="ALL"
 EASI>REPORT=
 EASI>RUN AVHRRAD

Example 5

Generate satellite zenith angle, solar zenith angle, and relative azimuth angle values into the output PIX file.

 EASI>FILI="AVHRR.PIX"
 EASI>FILO="ANGLES.PIX"
 EASI>DBIC=
 EASI>DBOC=1,2,3
 EASI>AVHRRSEG=
 EASI>CTYPE="ANG"
 EASI>REPORT=
 EASI>RUN AVHRRAD
