Introduction

Different chemical schemes in the model

3 different in TM5, 2 different in TM4

Need for evaluation of different rates/schemes

Impact of the update of rates

Easy to use, fast, representative

Review chemistry over height

Use of single column model

WUSCM coupled with KPP for chemistry.

TM4 IUPAC vs JPL — O3

TM4 IUPAC vs JPL — CO

TM4 IUPAC vs JPL — Isoprene

TM5 old vs new — O3

TM5 old vs new — CO

TM5 old vs new — Isoprene

TM5 vs CBM5 — O3

TM5 vs CBM5 — CO

TM5 vs CBM5 — Isoprene

All mechanisms — O3

All mechanisms — CO

All mechanisms — OH

All mechanisms — HO2

All mechanisms — NO

All mechanisms — NO2

All mechanisms — CH4

All mechanisms — Isoprene

Conclusions

Use of the single column model gives a good, fast validation

Easy to discover mistakes, correct them, re-evaluate

More information than the 0D model (height)

Thank you!!!
