One of the pillars of my research is the development and deployment of instrumentation for measurement of trace gases from airborne platforms at a high accuracy.
A number of modeling tools are in development in a continued collaboration with the Wofsy group at Harvard and with John Lin (formerly at Harvard, now at Waterloo). These tools are elements of a model-data fusion system designed to extract information from a variety of data streams, with special emphasis on airborne or ground based greenhouse gas gas measurements.
A fast tool to retrieve the tracer adjoint (sensitivity of atmospheric tracer mixing ratio measured at receptor point with respect to upstream variations in surface fluxes), including turbulence. This is also used in forecast mode for flight planning purposes (examples).
A diagnostic biosphere model to compute fluxes consistent with fluxes observed by Eddy Covariance. VPRM is a light use efficency (LUE) model, and uses the MODIS EVI (enhanced vegetation index) and LSWI (land surface water index) as well as vegetation classification (e.g. Synmap). Four parameters are optimized against measurements for each vegetation type. This work is in collaboration with Steve Wofsy at Harvard.
An regional inversion framework to assimilate information from multiple data streams for retrieving regional fluxes. It uses STILT footprints, prior fluxes from VPRM and others, gridded emission inventories, and ocean fluxes to derive optimized biosphere-atmosphere flux estimates from atmospheric observations such as from ICOS. To account for lateral boundary conditions, it is used in sequence with the CarboScope system on a global scale.
Coupling of WRF-Chem with models for biospheric CO2 fluxes (VPRM), natural fluxes for CH4, and anthropogenic fluxes for CH4, CO2, and CO. A fully scalable modelling approach ranging from mesoscales at 1 km to 20 km or coarser. This is also used in forecasting mode to assist flight planning during campaigns.
Consistent coupling of WRF transport to the STILT model, by using consistent mass fluxes (advective and convective) as well as consistent turbulence parameters. This work was done in collaboration with Thomas Nehrkorn and Janusz Eluskiewicz at AER.
