A wavelet-based approach to streamflow event identification and modeled...
Streamflow timing errors (in the units of time) are rarely explicitly evaluated but are useful for model evaluation and development. Wavelet-based approaches have been shown to...- publication PDF

An Ensemble approach for the estimation of observational error illustrated...
Least squares algorithms for data assimilation require estimates of both background error covariances and observational error covariances. The specification of these errors is...- publication PDF

Observational validation of parameterized gravity waves from tropical...
Tropical gravity waves that are generated by convection are generally too small in scale and too high in frequency to be resolved in global climate models, yet their drag forces...- publication PDF

Understanding the drivers for the 20th century change of hydrogen peroxide...
Observations and model simulations of an Antarctic ice-core record of hydrogen peroxide during the last ~150 years are analyzed. The observations indicate a relative increase in...- publication PDF
