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.

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)
