1. The LBNL submission Fabian Wagner (joint work with Jayant Sathaye, LBNL)

2. Introduction The International Energy Analysis Group is NOT a climate modelling group Development of LeCLIPBS Reference implementation (Test of the terms of reference!) Interface Sensitivity Analysis

3. One up (dT)…

4. … one down (SL)

5. CH4

6. The Interface

9. Continuity of emission data Systematic tuning (of ALL indicators) Discourage use of 10-year steps for emissions (CH4 lifetime is of that order) Issues

10. Capacity building has worked for us! Adequate Entry Level Implementation in EXCEL possible Little manpower required Developed interface for sensitivity analysis (willing to share!) 10-year steps for emissions problematic (due to shorter lifetime of CH4) Conclusions

11. Thank you!
