This is my second email about the Environmental Modeling program. Since the email list has somewhat expanded since the first email was sent, I am including the first email also as an attachment to this email. The next meeting of the group will be Wednesday morning, Jan 15, at 11:00 a.m. in the NISS conference room (first floor of the NISS/SAMSI building). In our first meeting last week, participants were invited to list the topics they are currently researching or interested in researching during this program. Among the topics mentioned were: Fluid dynamics PDEs with random or variable coefficients Fat-tailed distributions arising in nature Unresolvable parameters in systems of PDEs The interface of mesoscale atmospheric models with global models Multiphase porous media systems and their applications to groundwater flow: fundamental properties, conservation relations, multiscale aspects, numerical solutions Problem-solving environments and code generators for porous media systems. Stochastic aspects and spatial statistics. Optimization in non-linear porous media systems: large systems of nonlinear equations, problems with non-smooth nonlinearities Air pollution and human health, esp. re. sources of pollution Design of a monitoring network, including what kind of design is appropriate if interest is in monitoring extremes Estimating human exposure to atmospheric pollutants Approximating maximum likelihood estimators in large spatial statistics problems Nonstationary spatial statistics Quantifying uncertainty in numerical models Ensemble forecasting Extreme values and spatial statistics; applications to global climate change Nonparametric spatial statistics Statistical methods to estimate parameters and assess uncertainties in large numerical models Biodiversity in forest systems Relating measured trends in atmospheric pollutions to emissions reductions How to incorporate uncertainty measures into environmental standards based on threshold exceedances Evaluation and applications of EPA atmospheric models Spatial-temporal variability of air quality data Data assimilation in ocean models - assessing Lagrangian transport from underwater traces Statistical aspects of data assimilation Predictability of ocean fields based on sparse data: statistics vs. dynamical system approaches Spatial-temporal ozone modeling Relationship between environmental models and other approaches to the evaluation of computer models in engineering - Bayesian approaches to prediction keeping track of uncertainty in parameter estimation Detection of climate change - validation of large couple ocean-atmosphere models for the climate Changes in climatic extremes- indicators of extreme climatic events Applications of fluid mechanics in the natural environment Synthetic data in numerical models Spatial-temporal analysis of particulate matter - selecting covariance structures, uncertainty of predicted values Testing for stationarity in spatial models FUTURE PLANS: We have three more meetings before the multiscale modeling workshop (Feb 2-7). It was agreed to spend most of this time on short (15-minute) presentations to allow group members to outline their current work. A provisional schedule is as follows. Jan 15: Jim Zidek, Tim Kelley, Rich McLaughlin, Casey Miller, Richard Smith Jan 22: Gabriele Hegerl, Montse Fuentes, Robert Wolpert, Jie Yu, Jim Berger Jan 29: Chris Jones, Brian Eder, Dave Holland, Amy Grady, Amy Nail RLS 01/14/03
