Data Assimilation of satellite observations into atmospheric models has been responsible for considerable improvements in the forecast ability of NWP. Consequently there is considerable effort being invested in applying these techniques to the land surface models also. This talk focuses on models of carbon flux between forests and the atmosphere and explores some ideas about the nature of the satellite data we should be using and what the problems therein might be. Specifically it looks at the use of non-linear observation operators to assimilate observations of canopy reflectance acquired by NASA MODIS, which flies on-board the Terra and Aqua satellites, into the simple ecosystem model DALEC. Problems of consistency in the physics of the model and the observation operator are discussed.

All visitors without NOAA or University of Oklahoma identification must register at the registration desk on arrival. Visitor parking is available for all University visitors. However, faculty/staff/students must have a current multi-purpose parking permit. Additional parking is available at the Lloyd Noble Center (LNC) for those individuals who do not have a parking permit. You do not need a permit to park in one of 1,200 spaces reserved for CART bus riders, although you must ride the CART shuttle to park in the reserved area. This area is on the north central side of the Lloyd Noble Center. Elsewhere at the LNC, permits are required. The University of Oklahoma is a smoke-free / tobacco-free campus.
