Department of Chemical Engineering, Columbia University, NY

Multiphase Atmospheric Chemistry: From the molecular to the regional and global scales

"Multiphase chemistry in the atmosphere is a major source of organic and inorganic atmospheric particulate matter, and also has a profound influence on gas-phase composition and precipitation chemistry. Despite considerable progress, mechanistic understanding of some key aqueous atmospheric processes is still lacking, and their representation is incomplete in most regional and global models. I will present an overview of aqueous chemical processes in the atmosphere, highlighting recent developments and critical uncertainties. I will also discuss my group’s efforts in characterizing these processes in the laboratory and improving their representation in atmospheric chemistry models."

CSTPR Noontime Seminar

CSTPR Noontime Seminar

Guiding ozone layer recovery with effective science and policy on an international scale

by Stephen Montzka, NOAA/Earth System Research Laboratory/Global Monitoring Division

Abstract: Depletion of Earth's vital ozone layer was first noticed in the mid-1980s over Antarctica. As it became clear that human-produced chemicals were the source of the problem, all countries of the world convened and agreed to an international protocol in 1987 to address the issue. The Montreal Protocol on Substances that Deplete the Ozone Layer has been adjusted and amended numerous times in response to advances in scientific understanding. This interplay between new scientific knowledge and international policy continues today and has recently been put to the test with our discovery in 2018 of an apparent violation of the Protocol by a country or countries (Montzka et. al, 2018, and Rigby et al., 2019). In this presentation Steve will discuss the issue of ozone depletion, the general mechanisms of the Protocol, highlight the observational evidence we have acquired indicating an apparent violation, and describe how the Parties to the Protocol have responded to the problem, which can be viewed as a fundamental threat to the success of the Protocol and ozone layer recovery.

Biography: Steve Montzka has worked as a research chemist at NOAA since the early 1990s. He leads a ongoing global-scale program making atmospheric measurements of over 30 chemicals that affect stratospheric ozone, climate, and air quality. He still gets a kick out of uncovering new insights into the workings of the global atmosphere those data provide, and using his results to inform policymakers on the international stage about the effectiveness of global environmental agreements, such as the Montreal Protocol on Substances that Deplete the Ozone Layer.

NSIDC Cryosphere Seminar

Visual Analytics and Interactive Machine Learning for Geospatial Sciences by Dr. Morteza Karimzadeh, Assistant Professor, Department of Geography, CU Boulder

Machine learning is increasingly used in various stages of scientific inquiry, from data cleaning and fusion, to analysis and insight generation. The full realization of machine learning in many scenarios is still limited by the sparsity of labeled training data, which is expensive and difficult to generate. Even when available, labeled training datasets capture a snapshot in time and space, resulting in models that may not perform well under different conditions. Additionally, models may reflect the biases inherent in the training data. In this talk, I will present on multiple interactive visual analytics frameworks for the simultaneous labeling, learning and analysis of data in two different domains, namely streaming social media document analytics and feature selection in hyperspectral imagery for precision agriculture. Both represent cases with spatiotemporal heterogeneity and limited training data for building performant models. In presenting these visual analytics approaches, I will break down the underlying computational components and the interactive interfaces, and draw connections on how such approaches can be adopted in cryospheric data and research, as well as other domains utilizing multi-source, dynamic and streaming data.

Development of a “Lab-on-a-chip” platform, Victoria Arau, CU Boulder ANYL 1st year student, Browne group

and Very Remote Field Studies of Frost Formation on Mars Using the Curiosity Rover, Raina Gough, CU ANYL Research Scientist, Tolbert Group

Arau: "Current detection methods for environmental contaminants (which include but are not limited to HPLC, GC-MS, LC-MS, and LC-MS/MS) are generally time-consuming, expensive, and lack portability, limiting field deployment. Herein we evaluate a microfluidic electrochemical cell with viability for an in situ field deployment. The microfluidic channel consists of an interdigitated microelectrode and granulated activated carbon electrodes for optimized sensitivity. Electrochemical response is monitored using cyclic voltammetry with a known redox standard, with consistency in this response between macroelectrode systems and this microelectrode system. The linearity of the peak-current versus square root of scan rate demonstrates chemical reversibility, suggesting operability of this device. Results here suggest feasibility for further development of this technology as a sensor with real-time in situ capabilities. "

and

Gough: "For the last 3 years, I have been a Participating Scientist on the Mars Science Laboratory (aka: Curiosity) mission. This rover has traversed the Martian surface since 2012, totaling 4 full Mars years of environmental and geological observations. In this talk, I will summarize some of the most interesting results from the mission and talk about my role in planning the rover's science operations. I will also discuss a series of frost-detection experiments performed on Mars that I helped to lead. Although there is little water vapor on Mars, it is expected that water exchanges seasonally and diurnally with the surface. The rover’s weather station had predicted that frost should indeed form on the soil in the early morning in the winter. However, no condensed phase water had been observed along the rover’s traverse, until recently. Last November, we successfully used the rover’s laser-induced breakdown spectroscopy (LIBS) instrument to detect enhanced hydrogen on the soil just before dawn. We believe that this indicates the presence of diurnally exchanged water, potentially frost. I will discuss these results, and also some of the unexpected hurdles to performing science on Mars."

CIRES Virtual Town Halls

CIRES Virtual Town Halls

As we begin to work remotely, CIRES leadership is staying connected:

CIRES Director Waleed Abdalati plans to host two virtual “town halls” for CIRES staff: one primarily for people who normally work in the DSRC, the other CU Boulder campus-based staff. Each of these is limited to 300 participants; we will record or offer a third slot if anyone is excluded.

The CIRES senior management team will be there to help address concerns and questions as best we can. Some of your questions cannot be answered right now. Along with our colleagues at CU Boulder and NOAA, we are doing our best to get answers quickly. CU Boulder is soliciting questions and posting FAQ answers here. CIRES is accepting CIRES-specific questions through this link.

 

CIRES Virtual Town Halls, Monday, March 16—JOIN ONE OF THE FOLLOWING:

10 a.m. (for those who normally work in DSRC): https://cuboulder.zoom.us/j/859132028

How (and Why) to Make a Research Compendium with Dr. Max Joseph – An Earth Analytics Career Webinar

How (and Why) to Make a Research Compendium with Dr. Max Joseph – An Earth Analytics Career Webinar

Earth Lab invites you to How (and Why) to Make a Research Compendium with Dr. Max Joseph – An Earth Analytics Career Webinar on Thursday March 19th, from 12-1pm.

How do you bundle up the analysis associated with a research project? How can you ensure that other people can install the same software dependencies and run the same workflow on their machines? Research compendia provide one answer to these questions. A research compendium is a key component of open and reproducible science, accompanying a scientific paper and providing the data, code, and documentation required to reproduce the workflow. The central idea is to treat your analysis pipeline as software, and bundle it up into an installable, executable package. Dr. Max Joseph will offer pro tips on getting started with research compendia, and discuss how it can benefit you as a scientist. Anyone interested in open science and how to make their own work more open and reproducible should attend.

You can register for the event and join with the link below. The event will be recorded and posted on the Earth Lab website for those who are interested but cannot attend.
