Software Version 4AOP2012v1.0 released

Date: 2012, March

What is new since 4AOP2009v1.2:

• Added user option to simulate scattering effects of clouds (cirrus…)
• New atlases of pre-calculated optical thicknesses that include:
  • an improvement for effects of CO₂ line-mixing
  • the new GEISA 2009 spectroscopy
  • the pressure shift for H₂O, CO₂ and N₂O
  • updated reference gas mixing ratio profiles
  • improved TIPS’ formulation
• Minor bug fixes in a few routines of the model
• Updated and improved Graphical User Interface

What is new since 4AOP2009v1.0:

• Minor bug fixes in a few routines of the model and of the GUI and in the user installation process.

What is new in 4AOP2009:

• Implementation of the limb viewing geometry:
  • Refined geometry module
  • Option for limb view simulation
  • Height dependence of gravity acceleration
• Implementation of the user option to simulate scattering effects (coupling with DISORT and SOS codes). Option is active only in Earth view geometry and for aerosols
• New atlases of pre-calculated optical thicknesses:
  • that make the code more precise
  • that include:
    • an updated line-mixing for CO₂
    • the new GEISA 2008 spectroscopy
    • the pressure shift for H₂O
    • updated gas mixing ratio profiles,
    • improved CFC’s formulation
• Minor bug fixes in a few routines of the model
• Updated and improved Graphical User Interface
