Open Source Software for Geospatial Applications (FOSS4G): The basics, sample applications and how it is taught at the University of Colorado Denver.
Dr.  Rafael Moreno-Sanchez
This presentation is aimed at a broad audience of scientists from those new to FOSS4G to the ones already working with GIS. First the basics of FOSS and FOSS4G will be covered: What is it? Advantages and challenges of working with FOSS4G. Overview of mature FOSS4G options for the most common GIS needs. Samples of student work will be presented to demonstrate the proficiency that can be achieved in a relatively short time. Finally, we will present how we are using and teaching FOSS4G at the University of Colorado Denver.
Rafael Moreno-Sanchez is an Associate Professor in the Department of Geography and Environmental Sciences at the University of Colorado Denver.  His current research concentrates on the analysis of fragmentation and anthropogenic pressure on the forest areas, Decision Support Systems for forest management, and the use of Geospatial Open Source Software for creating local and Web-based spatial information systems.

Ensemble Visualization and Uncertainty Characterization Using Generalized Notions of Data Depth
Mahsa Mirzargar
University of Utah


When computational methods or predictive simulations are used to model complex phenomena such as dynamics of physical systems, researchers, analysts and decision makers are not only interested in understanding the data but also interested in understanding the uncertainty present in the data. In such situations, using ensembles is a common approach to accounting for the uncertainty or, in a broader sense, exploring the possible outcomes of a model. Visualization, as an integral component of data analysis task, can significantly facilitate the communication of the characteristics of an ensemble including uncertainty information. Designing visualization schemes suitable for exploration of ensembles is specifically challenging if the quantities of interest are derived feature-sets such as isocontours or streamlines rather than fields of data. 

In this talk, I will introduce novel ensemble visualization paradigms that use a class of nonparametric statistical analysis techniques called data depth to derive robust statistical summaries from an ensemble of feature-sets (from scalar or vector fields). This class of visualization techniques is based on the generalization of conventional univariate boxplots. Generalizing boxplots provides an intuitive yet rigorous approach to studying variability while preserving the main features shared among the members. It also aids in highlighting descriptive information such as the most representative ensemble member (median) and potential outlying members. The nonparametric nature and robustness of data depth analysis and boxplot visualization make such ensemble visualization schemes an advantageous approach to studying uncertainty in various applications ranging from image analysis to fluid simulation to weather and climate modeling.

ACOM is proud to present the following seminar.

This presentation introduces the characteristics, sources, dynamics and impacts of the gravity waves generated in the moist baroclinic jet-front systems. Firstly, a series of high-resolution cloud-permitting simulations of idealized moist baroclinic waves are performed to study gravity waves among moist baroclinic jet-front systems with varying degree of convective instability, to examine the similarities and differences of wave characteristics, initiations and propagations among different simulations, and to understand the coupling and interactions of gravity waves with small-scale moist convection and large-scale background baroclinic waves. Secondly, four-dimensional linear ray-tracing experiments are employed to investigate the source mechanisms, propagating characteristics, life cycles, and wavenumber vector refraction budget analysis of the identified lower-stratospheric gravity waves. Thirdly, spectral characteristics are estimated with discrete Fourier transform to assess the wave-induced momentum fluxes and their impacts on the large-scale circulation. Understanding the dynamics, propagations and impacts of these gravity waves may ultimately help us with better parameterizations of gravity waves associated with moist baroclinic jet-front systems.

As the weather turns warm, more and more people are out and about, including pedestrians, bicyclists and motorcyclists. It is especially important for motorists and cyclists to obey stop signs and speed limits at all our facilities. Pedestrians do have the right of way at marked and unmarked crosswalks, but should not enter the crosswalk when traffic is approaching. Motorists must yield to bicyclists and pedestrians, bicyclists must yield to pedestrians. Cyclists, drivers, and pedestrians all play a key role in keeping our campuses safe.

The NCAR Community Art Program proudly presents two new exhibits:


Gay E. Lasher’s work combines digital photography, printing and computers and is expressed in the medium of textiles. As an artist, she is concerned with ideas of transformation and re-creation. Lasher is fascinated by the potential that even common photographs can be reborn in a new and completely different way. Using features of Adobe Photoshop, she transforms ordinary photographs into abstract images. Small areas are then greatly enlarged to produce the final composition which is printed on cotton. She then uses black thread and stitching to sharpen the image, create depth, and give the surface a sculptural quality. In this show Lasher is presenting selected works from her Transformations and Playing in Traffic series. Lasher's work will be on exhibit in the Community Art Gallery l of the National Center for Atmospheric Research Mesa Lab March 30, 2015 through May 30, 2015.


Over the past ten years, Michael “m.g.” Davis has explored the character of distinctly Western icons such as the horse and saddle, grain elevators, and Airstream trailers, and has sought to capture common Front Range landscapes in an uncommon style—Pointillism2. The style, employing gentle abstraction, allows Davis to recreate underappreciated objects and places which he injects with new energy through unexpected contexts and the use of vibrant color. Davis will feature two works in this show never before exhibited publicly. Davis's work will be on exhibit in the Community Art Gallery ll of the National Center for Atmospheric Research Mesa Lab March 30, 2015 through May 30, 2015.

During the labs, the instructors work with students to help them write NCL programs for analyzing their own data.

Limited travel funds are available for eligible students or faculty members at minority serving institutions in the United States, or from universities in EPSCoR states.

Registration is free and limited to 16 students per class, so be sure to register as soon as possible.
