Status Update

Western Biogenic EI Improvement Project

• Comparisons of emission inventories from SMOKE BEIS v3.14, MEGAN v2.04, MEGAN v2.10 for July 3 – 18, 2008 and January 3 – 18, 2008, with new WRF data

o No change to previous conclusion to use MEGAN v2.10

o Most results are presented at the end as “extra slides”

• Investigating isoprene emission and Photosynthetically Active Radiation (PAR) data from WRF and satellite

o Example results are presented today.

o Recommend using satellite PAR data for 2008 emission inventories

• Starting to evaluate WRF performance for cloud fraction

WRF Solar Radiation VS satellite PAR

MEGAN Model

WRF to MEGAN

PAR = 0.5 x SRAD

Where

• 0.5 is assumed that ½ of solar radiation is in 400-700nm band

• SRAD is solar radiation (w/m2)

Satellite to

MEGAN• From GEWEX/GCIP and GEWEX Americas Prediction Project (GAPP)

• Satellite reports PAR data used directly in MEGAN

• Pinker, et al., shows good performance between satellite and ground stations

WRF Solar Radiation VS satellite PAR under clear sky

ISOP WRF/MCIP ISOP Satellite Percent Difference

WRF/MCIP CCF Satellite CCF

Clear sky

• ISOP from WRF/MCIP PAR is higher up to 40%.

Summary

Western Biogenic EI Improvement Project

• The new WRF data do not change the conclusion to use MEGANv2.10 for 2008 biogenic inventory

• WRF/MCIP PAR results in > 30% higher isoprene emission than satellite PAR, especially during the peak hours

• Difference occurs under clear skies: not due to cloud fraction

• Calculating PAR as a fraction of WRF Short Wave radiation is part of the problem

• Recommend using satellite PAR data

• Limited satellite data coverage for Canada and Mexico not a major shortcoming for this project

• Working on converting satellite cloud fraction to a workable format for comparison with WRF/MCIP

Western Biogenics EI Improvement Project

Next Steps

• Proceed with 2008 inventory using satellite PAR data

o QA satellite PAR data to find and fill any data gaps

o Process biogenic emissions for all of 2008 for the 3 domains

• Proceed with cloud fraction analysis to assist with WRF evaluation

Extra Slides

• Comparisons between SMKBEIS 3.14, MEGAN 2.04, and MEGAN 2.10– Using PAR = 0.5 x SRAD
