On April 21st, Sarah Shivers returned to her K-12 alma mater Berkeley Preparatory School in Tampa, Florida as their invited speaker for Science Discovery Day. Sarah spent the day teaching over 100 students in the 4th and 5th grades about satellites and how we study Earth from space. She also had the opportunity to meet with a dedicated group of high school students to chat about remote sensing and careers in science as part of their Science Cafe series. Sarah had a great time connecting with students and having the opportunity to share her love for science with them!

Erin Wetherley wins the AMS presentation award

Erin Wetherley received the Board of Urban Environment (BUE)'s Outstanding Poster Presentation award at the American Meteorological Society Annual Meeting which was held in Seattle, WA January 22-26. At the 13th Symposium of the Urban Environment, the BUE committee attends the student presentations and each member casts their votes for the best oral or poster papers taking into consideration: scientific merit, contribution to the field of urban environment, as well as presentation skills. Only the top three presentations are awarded cash prizes and a certificate. Erin's poster was titled, "Urban composition and surface temperature at multiple resolutions using airborne spectroscopic and thermal imaging". This poster explored sub-pixel unmixing of urban surfaces and investigating patterns between mixtures of material fractions and land surface temperature. Check out her poster on the first floor Ellison Hall!

Dar Roberts receives AGU Fellow Award

At the annual fall AGU meeting, VIPERs gathered to watch Dar Roberts receive the prestigious AGU Fellow Award. Established in 1962, the Union Fellows program recognizes AGU members who made exceptional contributions to Earth and space sciences as valued by their peers. Oliver Chadwick nominated Dar for developing spectral mixing models that drive pixel-based interpretation of remote sensing data to solve environmental problems. At the Honors Ceremony, VIPERs watched Dar receive his award, while also earning the title of most raucous cheering crowd. After the ceremony, Dar fans gathered for champagne toasts and a group photo (see below). Following the champagne reception, a banquet was held to celebrate all AGU honorees. In addition to wonderful food, the banquet hosted a photo booth help to commemorate the night. The evening ended with fantastic music and dancing. Dar Roberts even danced with AGU President Margaret Leinen! 

Viper's Attend AGU 2016

The American Geophysical Union (AGU) held it's annual fall meeting in San Francisco December 12 - 16, 2016. With approximately 24,000 attendees in 2015, AGU’s Fall Meeting is the largest Earth and space science meeting in the world. This year will mark Fall Meeting’s 49th year as the premiere place to present your research; hear about the latest discoveries, trends, and challenges in the field; and network with colleagues that can enhance your career. The majority of the VIPER lab made the trip up north to present their current research including: Alana Ayasse, Gabriel Daldegan, Susan Meerdink, Fernanda Ribeiro, Sarah Shivers, Zach Tane, and Erin Wetherley. In addition the vipers were joined by Dar Roberts who presented current research at AGU. 

Vipers attend 2016 HyspIRI Workshop

posted Oct 22, 2016, 8:48 AM by Susan Meerdink   [ updated Oct 22, 2016, 8:49 AM ]

Four members of the Viper Lab attended the 2016 HyspIRI Science Workshop at Caltech. This workshop provided an update on mission status and ongoing science results for the proposed HyspIRI satellite mission. This workshop always provides a diverse sampling of ongoing spectroscopy projects in a variety of topics. Advisor Dar Roberts presented a talk titled "Developing Methods for Fractional Cover Estimation Toward Global Mapping of Ecosystem Composition".  Susan Meerdink presented a talk titled "Spectral emissivity features of plants: Prospects for the Hyperspectral Thermal Emission Spectrometer (HyTES) sensor". In addition, Alana Ayasse and Sarah Shivers attended the workshop for a couple days. Also attending the three day workshop were a couple of Viper alumni who also gave presentations: Phil Dennison and Andrew Thorpe. Slides from the above mentioned presentations will be available on this website: http://hyspiri.jpl.nasa.gov/events/2016-hyspiri-science-and-applications-workshop

NASA and USFS Facebook Live with Zach Tane

posted Sep 1, 2016, 11:46 AM by Susan Meerdink   [ updated Sep 1, 2016, 11:50 AM ]

On August 30 at 11 am, scientists Natasha Stavros from NASA and Zach Tane (VIPER lab PhD candidate) with the U.S. Forest Service were found on NASA Earth's facebook page hosting a facebook live event. They discussed way NASA data and technology are helping the Forest Service understand wildfire behavior and improve wildfire recovery. With Griffith Park as their backdrop, Zach and Natasha explained how remote sensing can aid wildfire prevention, status, and recovery. Zach explained how spectroscopy using AVIRIS is a great tool for forest management. People from around the world logged on and asked questions about wildfires in California.

Dar Roberts named AGU Fellow

posted Jul 26, 2016, 11:21 AM by Susan Meerdink   [ updated Jul 26, 2016, 11:21 AM ]

The American Geophysical Union (AGU) today announced its 2016 Fellows, an honor given to individual AGU members who have made exceptional scientific contributions and gained prominence in their respective fields of Earth and space sciences. Since the AGU Fellows program was established in 1962, and according to the organization’s bylaws, no more than 0.01 percent of the total membership of AGU is recognized annually. This year’s class of Fellows are geographically diverse coming from 18 states and eight countries.

“Although AGU Fellows represent the many diverse sciences of AGU members and come from different career backgrounds, they’ve each played a leading role in promoting discovery and developing solutions for a sustainable future for Earth,” said Margaret Leinen, AGU President. “We’re pleased to recognize and honor the newest class of Fellows for their significant and lasting contributions to Earth and space sciences.”

Our very own Dr. Dar Roberts has been chosen as an AGU fellow. He will be honored at the AGU annual meeting in San Francisco.

PhD alumni Andrew Thorpe published in Washington Post

Recent research on the massive Aliso Canyon methane gas leak of late last year, conducted by researchers including Viper Lab PhD alumni Andrew Thorpe, was featured in The Washington Post after initial publication in the journal Geophysical Research Letters. The size of the leak was of such large proportion that a NASA satellite could see the plumes of gas from space.
