3. HITRAN2016 trace gases update :
Outline:
New line lists for NH3, HNO3, OCS, HCN, CH3Cl, C2H2, C2H6, PH3, C2H4, CH3CN, CF4, C4H2, SO3, C2N2 and COCl2
Traditional Voigt line shape parameters : gair, gself, nair
Common expression nair = 0.79nN nO2
Non-Voigt line shape parameters (SDV, HT profile)
The semi-empirical line shape parameters from forgein broadeners (like CO2, H2, He)

4. Ammonia –NH3( molecule 11) :
Validate the new line list for NH3
2012
2012
By comparing with the PNNL corss-section data, we found that the current MARVEL/BYTe combination is still incomplete to provide the input to HITRAN for cm-1.

5. Ammonia –NH3( molecule 11) :
New to HITRAN
New lines above 7400 cm-1
So the present update includes lines in the region 7400–10350 cm-1 which came from analysis of the Kitt Peak spectrum.

10. Air-broadening temperature dependence exponent nair:
Eq1:
Incorrect
Eq2:
Right way!
