MAERISST Source Installation in Linux

Overview

MAERISST is a retrieval algorithm for obtaining sea surface skin temperature based on Marine-AERI observations of the ocean and sky.
The observational requirements for MAERISST are M-AERI observations at sea at 55 degrees from nadir, 55 degrees from zenith, and zenith.

 

Installation in Linux

Note:  This package was tested on Red Hat 4.4.7-23, using gcc 4.4.7 20120313.  Modifications are likely needed for alternate operating systems, compilers and libraries.

Download then unzip installation package

$ unzip dev_maerisst.zip

 

Build ohwhio. This creates file libohwhio.a

$ cd dev/ohwhio
$ make -f Makefile.Linux

 

Build libutil. This creates file libutil.a

$ cd ../libutil
$ make -f makefile.linux

 

Build maerisst. This creates file maerisst.exe

$ cd ../maerisst
$ make

 

Input data

Required input data for MAERISST are

  • .RNC files from AERI
  • .SUM file from AERI
  • mirror.beg file used to collect AERI data
  • MAERISST.VIP specifies file locations for input, output, etc.
  • MAERISST.SIP specifies scene mirror position IDs, and other parameters
    • SceneMirPosIDzenithSky:  zenith position in mirror.beg (e.g. S)
    • SceneMirPosID1*TempCalc:  55 degrees from nadir position in mirror.beg (e.g. V)
    • SceneMirPosID2*TempCalc:  55 degress from zenith position in mirror.beg (e.g. W)

 

Running MAERISST

For the test case provided, AE960318

$ cd ../test_data
$ ../maerisst/maerisst.exe
$ 960318
$ 1

 

Output

Three output files are generated

  • maerisst.log, processing log file
  • acsiiout.mlt, ASCII datafile of SST
  • TSKINDMP.ASC, parameter file

For the test case provided, the test output can be found in  test_output

To verify that matching output is generated

$ diff TSKINDMP.ASC test_output/TSKINDMP.ASC
$ diff acsiiout.mlt test_output/acsiiout.mlt
$ diff maerisst.log test_output/maerisst.log
