Please note that this page is under construction. We are documenting the 240-node cluster maya that will be available after Summer 2014. Currently, the 84-node cluster tara still operates independently, until it becomes part of maya at the end of Summer 2014. Please see the 2013 Resources Pages under the Resources tab for tara information.

Biomass burning is getting increasing attention because large areas of the globe burn each year, and these fires emit large amounts of smoke and trace gases. In an attempt to find a relationship between total carbon monoxide (CO) production and fire radiative energy (FRE), a previous study has found proportionality between these two variables with a relatively high correlation coefficient. However, that study was performed under laboratory conditions, which might not replicate actual conditions in forest fires. In our work, we are using CO total columns retrieved from Terra-MOPITT and fire radiative power (FRP) measurements from Terra-MODIS to investigate a similar relationship for actual landscape fires. As a preliminary study for this task, we selected a few prominent fires that were observed from the Terra satellite. Interestingly, based on the analysis so far for the California fires in 2007, we have seen a convincing graphical association between CO total column and FRP. Once the process is completed for other fires, we are planning on utilizing this quantitative relationship between CO emission rates and FRP to derive CO emissions from fires globally for use in atmospheric models to forecast CO distribution. In this way, we will help improve forecast tools for biomass burning emissions, based on satellite data, which we can access in near real time. Moreover, this would positively contribute to the estimates of biomass burning contribution to global warming.
