MALT

• Calculates spectra for single homogeneous path or for multiple layers
• Includes instrumental parameters into the calculations so the calculated spectra match the line shape, resolution and wavelength shift of the measure spectra.
• Uses HITRAN molecular spectroscopy databases

HITRAN/MALT vs. Actual Calibration

• Advantages
• Calibration data free of noise
• Best match to the measured spectrum according to the least-squares criteria
• Operational costs reduction
• Non time consuming calibrations
• Precision at least as good as that of traditional methods ( £ 3%)1
• Disadvantages
• Provide analysis only over gases included in the HITRAN database
• System requires regeneration of calibration data if spectrometer or gas cell change
