3.3. O2 Products

The MEPIX tool can also derive products which will are of interest within the O2 project. These are:

The algorithms have been implemented based on the documentation and breadboard software provided by FUB and LISE. During two collocations the implementation was verified together with the algorithm developers.

3.3.1. Surface Pressure (FUB)

This algorithm was developed as IDL code by Free University of Berlin (FUB) and is described in [3]. The algorithm includes a new straylight correction scheme proposed by FUB (see [4]). Brockmann Consult provided a Java implementation in MEPIX. A validation with the original IDL code was performed by applying Junit tests on distinct test data provided by FUB.

3.3.2. TOA Pressure ('P1', LISE)

This algorithm was developed as FORTRAN code by LISE and is described in [5]. Brockmann Consult provided a Java implementation in MEPIX. A validation with the original FORTRAN code was performed by applying Junit tests on distinct test data provided by LISE.

3.3.3. Surface Pressure (LISE)

This algorithm was developed as FORTRAN code by LISE and is a slight extension of the TOA pressure using filter-dependent C coefficients. Brockmann Consult provided a Java implementation in MEPIX.

3.3.4. Rayleigh-corrected TOA Pressure ('P2', LISE)

This correction has been proposed by LISE to be applied on the TOA Pressure. This product is provided as additional band in MEPIX.

3.3.5. Aerosol apparent pressure ('PScatt', LISE)

This algorithm was developed as FORTRAN code by LISE and is described in [5]. Brockmann Consult provided a Java implementation in MEPIX. A validation with the original FORTRAN code was performed by applying Junit tests on distinct test data provided by LISE.
