Title:  Introduction to Statistics for Spatio-Temporal Data
Instructor: Christopher Wikle
Date: Fri., Mar. 3
Time: 8:30am - 4:30pm (see schedule below)
Location:  Main Seminar Room, National Center for Atmospheric Research (Mesa Lab), Boulder, CO

Abstract: The course gives a contemporary presentation of spatio-temporal processes and data analysis, bridging classic ideas with modern hierarchical statistical modeling concepts. From understanding environmental processes and climate trends to developing new technologies for mapping public-health data and the spread of invasive-species, there is a high demand for statistical analyses of data that take spatial, temporal, and spatio-temporal information into account. This course presents a systematic approach to key quantitative techniques for the statistical analysis of such data that features hierarchical statistical modeling, with an emphasis on dynamical spatio-temporal models. The material follows the book by Cressie and Wikle, Statistics for Spatio-Temporal Data (2011) - John Wiley and Sons, Hoboken, NJ.  Many examples will be included, along with some basic applications from various R packages. The course can be presented in a 1-day or 1/2-day format, with the 1-day format including more applications and software examples.

Prerequisite: Anyone with a Masters or PhD degree in Statistics is suggested, but required background assumes Masters level probability and statistical inference and good understanding of matrix algebra.

In Remembrance of Tom Horst 1943-2017

Long-time NCAR senior scientist Tom Horst passed away January 12th with his family by his side after a long and valiant battle with cancer. Tom’s scientific expertise was in micrometeorology with a focus on the measurement of surface fluxes and turbulence.  As an essential member of EOL, he has been involved in nearly all aspects of planetary boundary layer (PBL) research related to the surface layer, including theoretical developments, modeling, measurement programs, data analysis, and instrument development. Additionally, he’s been at the forefront of research on atmospheric diffusion, flux footprints, and measurement physics in the surface layer. Read the full tribute to Tom by colleague Terry Hock in EOL's newsletter here

STATMOS and SAMSI will be hosting a Workshop on Climate Statistics, July 17-21, at NCAR, in Boulder, Colorado.  The main purpose of this meeting is to facilitate interdisciplinary collaborations in climate statistics. Information about the workshop and a link to the application form can be found at the following link:

https://sites.google.com/a/uchicago.edu/ncar17/

This workshop may be of interest to STATMOS researchers at all levels.  The workshop will be small, about 30 total participants, of whom about half will be statisticians, so we likely will not be able to accommodate everyone who is interested, but we are seeking a diverse group of attendees in terms of specific interests and career stages, so all are encouraged to apply.  Note that applications are due March 31.

The STATMOS Annual Meeting will be held the day before the workshop begins, on July 16, also at NCAR, so people attending the workshop will find it convenient to also attend the Annual Meeting.

For more information, please contact Michael Stein at stein@galton.uchicago.edu.

News clips at a glance: Feb. 11 – 17

Total:  ~300

Summary: An Associated Press story focusing on the Cheyenne Supercomputer’s role in supporting climate research while based in the country's biggest coal-mining state has generated 150+ clips across the country and overseas. Coverage of a new study detecting a major change in ocean oxygen loss acknowledged earlier groundbreaking work by NCAR scientist Matthew Long.

Minnesota teenager Martha Burket cited our work and that of others in making a case that it's time to act to mitigate climate change. "When 97 percent of people with this scientific training draw the same conclusion, they create a collective voice that must be listened to," she wrote in a column carried by the Post-Bulletin newspaper in Rochester, Minn.

This workshop series is designed to help prepare the next generation of researchers and practitioners to work within, and contribute to, the data-rich era. Each workshop will bring together graduate students and senior scientists in environmental statistics and related fields to explore contemporary topics in applied environmental data modeling.

Across scientific fields, researchers face challenges coupling data with imperfect models to better understand variability in their system of interest. Inference garnered through these analyses support decisions with important economic, ecological, and social implications. Increasingly, the bottleneck for researchers is not access to data; rather, it is the need to identify and apply appropriate statistical methods using efficient software.

Workshop program and objectives

The workshop will consist of hands-on computing and modeling tutorials, presentations from graduate student participants, and invited talks from early career and established leaders in environmental data modeling. Tutorials and invited talks will address useful ideas and tools directly applicable to student participants' current and future research. 

Workshop participants will:

  • Develop new modeling and computing skills through hands-on analyses and lectures led by quantitative scientists
  • Share research findings and explore open questions within and at the interface of environmental, ecological, climatic, and statistical sciences
  • Learn about the National Center for Atmospheric Research (NCAR) and National Ecological Observatory Network (NEON) data resources that can facilitate scientific discovery

Workshop participants will also have ample time to enjoy the mountains and downtown Boulder.

Workshop tutorials:

    Climate data analytics
Instructor: Doug Nychka, Institute for Mathematics Applied to Geosciences, NCAR

    Introduction to Bayesian statistics and modeling for environmental and ecological data
Instructor: Alix Gitelman, Department of Statistics, Oregon State University

    Hierarchical models for spatio-temporal data analysis
Instructors:  Andrew Finley, Department of Forestry, Michigan State University

Application materials are due March 31 and notification will occur around April 4.

Oceanographic controls on the variability of ice-shelf basal melting and circulations of glacial meltwater in the Amundsen Sea of Ebayment

Toshi Kimura, Nansen Environ. Remote Sensing

Ice Shelves in the Amundsen Sea Embayment have thinned and accelerated the seaward flow of ice sheets upstream over recent decades. In particular, Pine Island Glacier (PIG) and its neighbour Thwaites Glacier have been highlighted as major drainage pathways for the West Antarctic Ice Sheet. The cause of such imbalance in ice sheets is due to change in ocean-driven melting of the ice shelves. We quantify the melting of ice shelves in the Amundsen Sea Embayment and oceanic conditions between 1991 and 2014 using a general circulation model. Observations and numerical models have shown that the ocean heat reaching to the ice shelves is sensitive to the depth of thermocline, which separates the cool, fresh surface waters from warm, salty deep waters.

Recent studies have argued that the convective deepening of the surface water at the calving front by polynya formations play a key role in changing the depth of the thermocline. We demonstrate that the seasonal cycle and interannual variabilities of ice-shelf basal melting are tightly coupled to the offshore zonal wind stress and the polynya formations only play a role when the offshore wind forcing is weak. The ocean driven ice-shelf melting is enhanced by an asymmetric response to changes in ocean heat transport anomalies at the continental shelf break: melting responds more rapidly to increase in ocean heat transport than decreases. This asymmetry is caused by the inland deepening of bathymetry under the ice shelf and the glacial meltwater circulation around the ice shelf.
