Brief Bio


Dr. Arlindo da Silva is a Research Meteorologist at the Global Modeling and Assimilation Office (GMAO, formerly DAO), NASA/Goddard Space Flight Center, where he has worked since 1994. Prior to joining the GMAO, Dr. da Silva held a faculty position at the University of Wisconsin-Milwaukee from 1990-1993, and was a Visiting Scientist at Princeton University/Geophysical Fluid Dynamics Laboratory from 1989-1990.

Originally trained as a physicist and atmospheric dynamicist, Dr. da Silva’s research has spanned a number of related topics in the last decades: dynamics of stationary and transient atmospheric waves, numerical modeling of Lake Michigan, estimation of fluxes of heat, momentum, and fresh water fluxes over the global oceans, climate diagnostics, including aerosol forcing of climate, hydrological cycle of the subtropics and Amazon basin and data assimilation. Since joining GSFC Dr. da Silva’s research has focused on techniques for 4-dimensional data assimilation, including physical-space analysis systems, error covariance modeling, forecast bias estimation and correction, quality control of observations, land-surface, precipitation, aerosol and constituent data assimilation. Dr. da Silva was the lead developer for the Physical-space Statistical Analysis System (PSAS), GEOS-4 atmospheric data assimilation system, the Quick Fire Emission Dataset (QFED), and the Goddard Aerosol Assimilation System within GEOS. Dr. da Silva was the data assimilation PI for the original Earth System Modeling Framework (ESMF) project and currently serves in the ESMF executive board. From 2014  to 2018 Dr. da Silva served as the Science Study Lead for the Aerosol-Cloud-Ecosystems (ACE) Decadal Survey Pre-formulation Study.  Currently, Dr. da Silva is the GSFC Science co-lead for the Aerosols and Clouds-Convection-Precipitation Decadal Survey Pre-formulation Study. 

Dr. da Silva has been active in the open source software community being the founder and main developer of the OpenGrADS Project (http://opengrads.org).

Research Interests


Global Aerosol Modeling and Data Assimilation

Earth Science: Aerosols

Development of global aerosol models and advanced data assimilation techniques for assimilating satellite measurements in such models. Application of these systems for air-quality forecasting, historical reanalyses, and observing system simulations in support of future NASA space missions. Curen activities include advancing the representation of aerosols in the GEOS-5 earth system model, application of Ensemble Kalman Filter (EnKF) algorithms for the assimilation of aerosol observations, and use of machine learning algorithms for aerosol retrievals.


Cloud Data Assimilation

Earth Science: Clouds

Development of advanced algorithms for assimilation of spaceborne cloud observations in global earth system models. Recent activities focus on the application of Bayesian inference for estimating the sub-grid p.d.f. of water vapor and cloud condensate from high resolution satellite data.


Biomass Burning Emissions

Earth Science: Fire

Estimation of biomass burning emissions for driving global earth system models. Recent activities have focused on top-down algorithms based on fire radiative power and data assimilation techniques leading to the development of the Quick Fire Emission Dataset (QFED).


Observing System Simulation Experiments (OSSE) for Clouds and Atmospheric Composition

Earth Science: Theory & Modeling

A model-base Observing System Simulation Experiment (OSSE) is a framework for numerical experimentation in which observables are simulated from fields generated by an earth system model, including a parameterized description of the observational error characteristics. Such simulations are performed in support of an experimental goal. Current focus is on the application of a rigorous OSSE methodology for cloud, aerosol and trace gases measurements to existing and future NASA observing missions.


Software Frameworks for Earth System Modeling and Data Assimilation

Earth Science: Theory & Modeling

Development of high-performance, flexible software infrastructure for building and coupling weather, climate, data assimilation and related Earth science applications. Specific activities include advancing the Earth System Modeling Framework (ESMF) through development of integrated development environments, and refiniment of usability layers such as MAPL and NUOPC for enhanced interoperability.
